Description
[0001] The invention relates to a composition and method for promoting plant root growth, and more specifically, a plant rooting composition based on freeze-dried coconut water.
[0002] In horticulture, plant propagation relates to the process of creating new plants from plant materials such as seeds (sexual propagation) and stem, root, or leave cuttings (asexual propagation). Plant propagation may include a rooting step to promote adventitious root growth. Plant rooting generally involves placing plant material (such as cuttings) under conditions which favour adventitious root growth.
[0003] Compositions for stimulating root growth are known. Many available rooting agents commonly rely on synthetically produced compounds that stimulate root growth.
[0004] There are also reported natural rooting agents based on ingredients. However, the efficacy of these natural rooting agents are based mainly on anecdotal observations.
[0005] It is desired to address one or more of the abovementioned issues, and/or to provide a plant rooting composition and/or a method for promoting plant growth, or to at least provide the public with a useful alternative.

[0028] The term "comprising" as used in this specification means "consisting at least in part of". When interpreting statements in this specification which include that term, the features, prefaced by that term in each statement, all need to be present but other features can also be present. Related terms such as "comprise" and "comprised" are to be interpreted in the same manner.
[0029] It is intended that reference to a range of numbers disclosed herein (for example, 1 to 10) also incorporates reference to all rational numbers within that range (for example, 1, 1.1, 2, 3, 3.9, 4, 5, 6, 6.5, 7, 8, 9 and 10) and also any range of rational numbers within that range (for example, 2 to 8, 1.5 to 5.5 and 3.1 to 4.7).
[0030] This invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more of said parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which this invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.
[0031] To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.
[0032] The invention will now be described by way of example only and with reference to the drawings which:
[0033] Figure 1 is a comparison of the growth of a plant cutting (Monstera standleyana) treated with the plant rooting composition of the present disclosure and an untreated plant cutting.
[0034] Figure 2 shows root development and growth in plant cuttings (Hoya carnosa) treated with a foliar spray of the plant rooting composition of a present disclosure and untreated plant cuttings.
[0035] The present disclosure provides a composition for promoting plant root growth based on ingredients containing naturally occurring phytohormones. Moreover, the ingredients may be freeze-dried to preserve the phytohormones and other beneficial components.
[0036] The composition of the present disclosure may broadly comprise freeze-dried coconut water having phytohormones including auxin, cytokinins, gibberellins, abscisic acid and salicylic acid; and a natural free-flow agent.
[0037] Compositions for promoting root growth are known. Many commercially available rooting agents are based on synthetically produced plant hormone precursors such as Indole-3-Butyric Acid (IBA) that are converted into the auxin indole 3-acetic acid (IAA) which is implicated in plant developmental processes.
[0038] There are also many reported natural rooting agents based on ingredients such as apple cider vinegar, honey, aloe vera, cinnamon and willow tea. However, the efficacy of these natural rooting agents are based mainly on anecdotal observations.
[0039] Coconut water or liquid endosperm is well known for its nutritional and health benefits. Studies have shown that the chemical composition of coconut water includes many components that may be beneficial for plant growth such as sugars, vitamins, minerals, amino acids and phytohormones. Due to its unique chemical composition, coconut water has been used in the plant tissue culture industry (see Yong, Jean W H et al. "The chemical composition and biological properties of coconut (Cocos nucifera L.) water." Molecules (Basel, Switzerland) vol. 14,12 5144-64. 9 Dec. 2009, doi:10.3390/moleculesl4l25144).
[0040] Coconut palms are generally cultivated in wet tropical climates which may limit the access to fresh coconut water to be used as plant rooting agents in non-tropical regions. Using imported fresh coconuts may not be viable due to the relatively high cost and limited shelf-life compared to commercially available synthetic rooting agents. Further, bottled coconut water are typically pasteurised which denatures the temperature sensitive phytohormones and nutrients that are responsible for plant growth and development making less effective as a rooting agent.
[0041] The plant rooting composition of the present disclosure may promote root (including adventitious root) growth and development at an improved or comparable rate with respect to synthetic rooting agents or fresh coconut water. In some embodiments, the planting rooting composition may increase the rooting rate, root length and root numbers in plants administered with the plant rooting composition of the present disclosure.
[0042] According to the present disclosure, the composition may comprise freeze-dried or lyophilised coconut water. The freeze-drying or lyophilisation process removes the water content by sublimation which keeps the coconut water at a sufficiently low temperature to preserve temperature sensitive compounds including phytohormones and other nutrients. Freeze-drying also improves the storability and shelf life of the composition.
[0043] The plant rooting composition of the present disclosure may broadly comprise phytohormones including auxin, cytokinins, gibberellins, abscisic acid, salicylic acid at suitably high concentrations and a natural free flow agent at a suitable ratio.
[0044] In one aspect, the plant rooting composition may comprise: • freeze-dried coconut water comprising at least about 100 nM total auxin, at least about 100 nM total cytokinins, at least about 35 nM total gibberellins, at least about 50 nM abscisic acid, and salicylic acid; and
* a natural free-flow agent in a ratio of about 70:30 to about 95:5.
[0045] Auxin have roles in plant growth and development including promoting cell division, and shoot and root growth and development. The main auxin in coconut water is indole 3-acetic acid (IAA).
[0046] In some embodiments, the composition may comprise auxin in concentrations of at least about 110, 120, 130, 150, 160, 170, 180, 190, or 200 nM, and suitable ranges may be selected from between any of these values.
[0047] In some embodiments, the auxin may be indole 3-acetic acid (IAA).
[0048] Cytokinins (CK) have roles in plant growth and development including cell division, controlling shoot meristems formation and activity, photosynthesis gene expression, leaf senescence, nutrient mobilisation and root growth. Cytokinins may stimulate cell division in leaf and shoot growth, as well as stimulating lateral growth of axillary buds. Coconut water may contain many types of cyctokinins, of which, kinetin and trans-zeatin derivatives are the most significant for plant growth and development.
[0049] In some embodiments, the composition may comprise total cytokinins in concentrations of at least about 110, 120, 130, 150, 160, 170, 180, 190, or 200 nM, and suitable ranges may be selected from between any of these values.
[0050] In some embodiments, the cyctokinins may selected from kinetin and/or trans Zeatin. In other embodiments the cytokinins may be selected from kinetin and trans-zeatin derivatives including but not limited to N-iopentenyladenine, dihydrozeatin, ortho-topolin, dihydrozeatin O-glucoside, trans-zeatin O-glucoside, trans-zeatin riboside, kinetin riboside and trans-zeatin riboside-5'-monophosphate.
[0051] Gibberellins may regulate various aspects of plant growth and development including seed germination, leaf expansion, flower development and epidermal cell elongation. Gibberellin 1 and gibberellin 3 are found in coconut water.
[0052] In some embodiments, the composition may comprise total gibberellins in concentrations of at least about 40, 45, 50, 55, 60, 65, 70, 75, 80, 90 or 100 nM, and suitable ranges may be selected from between any of these values.
[0053] In some embodiments, the gibberellins may comprise gibberellin 1 and gibberellin 3.
[0054] Abscisic acid may regulate root growth in the presence of environmental stress. Salicylic acid have roles in plant growth and development including mediating defence response against pathogens.
[0055] In some embodiments, the composition may comprise abscisic acid in concentrations of at least about 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, or 110 nM, and suitable ranges may be selected from between any of these values.
[0056] Free flow agents maintain the free-flow behaviour of powdered or granulated materials. The use of a free flow agent may improve the reconstitutability of the freeze-dried coconut water.
[0057] The composition may use a natural free flow agent, such as a starch based free flow agent including but not limited to tapioca, maize, corn, potato, wheat starch, or a combination thereof.
[0058] In some embodiments, the ratio of freeze-dried coconut powder to natural free flow agent may be about 70:30, 75:25, 80:20, 82:18, 85:15, 87:13, 90:10, 92:8, or 95:5, and suitable ranges may be selected from between any of these values, (for example, about :30 to about 95:5, about 70:30 to about 90:10, about 70:30 to about 85:15, about 75:25 to about 95:5, 75:25 to about 90:10, about 75:25 to about 85:15, about 80:20 to about 95:5, about 80:20 to about 90:10, about 80:20 to about 85:15).
[0059] In addition to phytohormones, coconut water may also comprise various vitamins and minerals that contribute to healthy plant development. In some embodiments, the freeze-dried coconut water may include vitamins and minerals including but not limited to iron, boron, copper, manganese, selenium, zinc, molybdenum, cobalt, magnesium, nitrogen, phosphorus, potassium, vitamin C, and sulphur.
[0060] In some embodiments, the plant rooting composition may further comprise natural ingredients that may enhance the efficacy of the plant rooting composition including one or more of willow bark extract, and seaweed extract.
[0061] In some embodiments, the composition may comprise at least 2, 3, 4, 5, 6, 7, 8, 9, or 10 % by weight of willow bark extract, and suitable ranges may be selected from between any of these values, (for example, about 2 to about 10, about 2 to about 8, 2 to about 5, about 2 to about 3, about 3 to about 10, about 3 to about 8, about 3 to about 6, about4to about10,about4to about8,about4to about6, about6 to about10, about6 to about 8 % by weight).
[0062] In some embodiments, the composition may comprise at least 2, 3, 4, 5, 6, 7, 8, 9, or 10 % by weight of seaweed extract, and suitable ranges may be selected from between any of these values, (for example, about 1 to about 10, about 2 to about 10, about 2 to about 8,2 to about5, about2 to about3,about3 toabout10, about3 toabout8,about3 to about 6, about4 to about10, about4 to about8,about4to about6, about6 to about10, about6 to about 8 % by weight).
[0063] In some embodiments, the plant rooting composition may be reconstituted using water or other suitable liquid to obtain a plant rooting solution. In some embodiments, rain or distilled water is used to reconstitute the plant rooting composition.
[0064] In some embodiments, the freeze-dried coconut water is produced using coconut water obtained from coconuts aged up to about 9 months after endocarp formation.
[0065] The present disclosure may provide a method for promoting rooting in a plant or plant material, the method may broadly comprise:
• administering to the plant or plant material an effective amount of a plant rooting composition comprising freeze-dried coconut water comprising at least about 100 nM total auxin, at least about 100 nM total cytokinins, at least about 35 nM total gibberellins, at least about 50 nM abscisic acid, and salicylic acid; and a natural free-flow agent in a ratio of about 70:30 to about 95:5; " repeating the administration at an effective frequency; and maintaining the administration regime for an effective amount of time.
[0066] The effective amount of plant rooting composition, effective frequency, effective period of administration may depend on the plant type (for example, softwood, semi hardwood, or hardwood).
[0067] In some embodiments, the plant rooting composition may be administered in a powder form. For example, the plant rooting composition may be added to and/or mixed with plant growing media, soil or other suitable plant growing substrates.
[0068] In some embodiments, the effective amount of a plant rooting composition may comprise about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15 g per litre of water or other suitable liquid, and suitable ranges may be selected from between any of these values, (for example, about 1 to about 15, about 1 to about 13, about 1 to about 10, about 1 to about 7, about2 to about15,about2 to about12, about2 to about8, about3 to about15, about3 to about11, about3 to about7, about4to about15,about4to about10,about5 to about15, about to about10,about6 to about15,about6to about12, about6to about9, about7to about 15, about 7 to about 10 g per litre of water or other suitable liquid).
[0069] In some embodiments, the effective frequency of administration may comprise weekly, twice weekly, thrice weekly, fortnightly or monthly.
[0070] In some embodiments, the effective amount of administration time may comprise one, two, three, four, five, six, seven, eight, nine, 10, 11, 12 weeks or more.

Examples
Example 1 - Effectiveness as a soaking solution
[0086] The purpose of this trial was to test the effectiveness of a soaking solution of the plant rooting composition in promoting plant development in plant cuttings.
[0087] Two plant cuttings were obtained from the same plant (Monstera standleyana). Cutting A was treated with the plant rooting composition and cutting B was maintained in water (control).
[0088] The cuttings were kept in a controlled environment using a humidity box with 18/6 lighting (on for 18 hours; off for 6 hours), a temperature of 22C at 80% humidity for the duration of the trial.
[0089] Both cuttings were propagated in water for 3 weeks before the start of the trial. The water is replaced weekly.
[0090] At the start of the trial, the cuttings were transferred to a light expanded clay aggregate (LECA) substrate. For cutting A, the water was replaced with a soaking solution of the plant rooting composition, prepared by dissolving 5g of the composition (comprising 82% freeze-dried coconut water and 18% free flow agent) in 500mL of water, for 6 hours once per week. Cutting B is left to grow in water. Both cuttings were replaced with fresh water weekly.
[0091] Apical growth on the cuttings were observed and measured (where growth is observed) and described below. Figure 1 is a comparison of the development of cutting A (treated with the plant rooting composition) and cutting B (control) over 75 days:
• Day 1 - both cuttings growing equally, with new apical growth developing.
• Day 25
o Cutting A - new apical growth observed (3 mm of new leaf height).
o Cutting B - no notable growth.
• Day 64
o Cutting A - new root growth (45mm and 7mm) and foliar growth observed (30 mm increase).
o Cutting B - no notable growth.
• Day 75
o Cutting A - root growth (50mm and 65mm) and new leaf has developed.
o Cutting B - new foliar growth is developing (3mm high).
[0092] The results show that the plant rooting composition of the present disclosure promotes plant development. In particular, the composition speeds up root and foliar growth.
Example 2 - Effectiveness as a foliar spray for stimulating root development
[0093] The purpose of this trial is to test the effectiveness of the plant rooting composition as a foliar spray to stimulate faster and increased growth in fresh cuttings.
[0094] Four plant cuttings were obtained from the same plant (Hoya camosa). Two cuttings were soaked in a solution of the plant rooting composition when the cuttings were first removed from the mother plant. The plant rooting composition is then applied as a foliar spray twice a week. The two remaining cuttings were sprayed with water (control).
[0095] The cuttings were kept in a controlled environment using a humidity box with 18/6 lighting (on for 18 hours; off for 6 hours), a temperature of 22°C at 80% humidity for the duration of the trial. The cuttings were kept on a medium of New Zealand sphagnum moss.
[0096] Five grams of the plant rooting composition (comprising 82% freeze-dried coconut water and 18% free flow agent) is dissolved in 500mL of water. Two cuttings (B and D) were allowed to soak in the solution of the plant rooting composition for 6 hours before being placed on in the sphagnum moss. Two control cutting (A and C) were soaked in water for 6 hours before being placed on in the sphagnum moss.
[0097] Cuttings B and D were then treated with the plant rooting composition (1g per 500mL) applied as a foliar spray twice a week for the duration of the two week trial. Cuttings A and C were sprayed with water twice a week for the duration of the two week trial.
[0098] Shown in Table 1 is the number of roots and total root length for each of cuttings A to D after two weeks. Figure 2 shows root development and growth in cuttings A to D at the start (Day 1) and end (Day 14) of the two week trial.
Table 1: Number of roots and total root length after two weeks.
Cutting Root 1 length Root 2 length Root 3 length Root 4 length Total root length (mm) (mm) (mm) (mm) (mm)
A (control) 18 - - 18
B 14 13 11 38
C (control) 18 11 - - 29
D 19 22 28 11 80
[0099] The trial indicates that the plant rooting composition of the present disclosure is effective as a rooting hormone. Cuttings treated with the present disclosure shows a total root mass increase of up to 176%.
Example 3 - Effectiveness in improving growth rate of plants
[0100] The purpose of this trial was to test the effectiveness of the plant rooting composition for encouraging faster growth in plants.
[0101] The trial compared two Capsicum annum plants: Plant B treated with a fertiliser and the plant rooting composition of the present disclosure, and Plant A (control) treated using only fertiliser.
[0102] The plants were obtained from seedlings of a similar size and from the same root stock at the beginning of the trial. The plants were kept in a greenhouse with natural lighting.
[0103] Both plants were given fertiliser once every two weeks. The fertiliser used was Burnet's Tom-a-rite Liquid Fertiliser at 7mL per litre. The fertiliser was applied as a soil drench once every two weeks and foliar spray once a month.
[0104] In addition to the fertiliser, Plant B was also treated with 5g per litre of the plant rooting composition (comprising 82% freeze-dried coconut water and 18% free flow agent) once per week. The plant rooting composition was applied as a soil drench and foliar spray with each application. Water was used as control for Plant A.
[0105] The difference in growth between Plant A and Plant B was observed and measured after three, five and eight weeks. Shown in Table 2 are the height of Plants A and B over the 8 week period of the trial.
Table 2: Height of untreated and treated over eight weeks
Time Plant Height (cm)
Start Plant A (control) 114
Plant B 114
Week 3 Plant A (control) 145
Plant B 150
Week 5 Plant A (control) 185
Plant B 205
Week 8 Plant A (control) 211
Plant B 251
[0106] Based on the results above, a 3% difference in height was observed between Plant A and B after three weeks, 10% after five weeks, and 17% after eight weeks. The results show that the plant rooting composition of the present disclosure improves the growth rate in plants.
