(54) METHOD OF PROMOTING FLOWERING
OF A FRUIT OR ORNAMENTAL PLANT
(71) I, RAMON CABANOS
BARBA of 428 Rhoda Mart, Subdivision
Anos, Los Banos, Laguna, Philippines, a citizen of the Philippines, do hereby declare the invention, for which I pray that a patent may be granted to me and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to earlier flowering of a fruit plant and to earlier flowering of an ornamental plant.
Readiness of a fruit plant or of an ornamental plant to flower can be regarded as being an aspect of physiological maturity.
This maturity depends on conditions of growth of the plant and its age. When conditions of growth can be expected to conform to normal conditions of growth for the plant, commencement of flowering can be expected to start at a particular period of agent of the plant. Commencement of flowering as a result of normal conditions of growth is referred to herein as being normal commencement of flowering.
According to the present invention, there is provided a method of treating a fruit plant or an ornamental plant wherein the aerial exterior of said plant has mature leaves, dormant leaves, mature flower buds, and dormant flower buds, so as to cause in a controlled manner commencement of flowering before normal commencement of flowering of said fruit plant or ornamental plant would occur, said method comprising: applying an aqueous solution to the aerial exterior of a said plant, said aqueous solution having an agent up to 3.0% w/v, said agent being selected from at least one of nitrate compounds, thiocyanate compounds, and thiourea compounds; and wherein said plant is selected from Eugenia cuminii, Citrus mitis, Citrus species,
Sandoricum koetlape. cashew, guava, grape, acerola, mangosteen, lanzone, orchid, bourgainvilla, hibiscus, azalea, mango, and pineapple.
Varous advantages can be obtained by using said method of the present invention.
For example, an increased number of flowers and/or greater uniformity of flowering can be provided. This is advantageous in the commercial production of ornamental plants. It is also advantageous in the commercial production of fruit, in that said method can enable a fruit plant to give fruit out of season and/or in greater number.
Subject to said requirement that said agent is present up to 3.0% w/v, the actual concentration of said agent will be chosen according to the plant to be treated, e.g. to avoid or reduce risk of leaf burn as a result of said application of said aqueous solution.
Examples of concentrations of said agent in said aqueous solution are: 0.1 to 3.0 / w/v; 0.1 to 1.5% w/v; 0.2 to 3.0% w/v; 0.25 to 2.0% w/v; and 0.5 to 3.0% w/v.
Preferred nitrate compounds, any number of which can be used are: ammonium nitrate, barium nitrate, calcium nitrate, magnesium nitrate, potassium nitrate, sodium nitrate, and nitric acid.
Preferred thiocyanate compounds, any number of which can be used, are: ammonium thiocyanate, barium thiocyanate, calcium thiocyanate, magnesium thiocyanate, potassium thiocyanate, and sodium thiocyanate.
Preferred aqueous solutions containing thiourea compounds comprise at least one of thiourea and ethylene thiourea.
If desired, further components can be present as additives in said aqueous solution. For example, said aqueous solution can comprise (a) up to 0.1% w/v of sodium naphthalene acetate and/or naphthalene acetic acid; and/or (b) up to 0.05% w/v of 2,4 - dichlorophenoxy acetic acid; and/or (c) up to 0.05% w/v of chloroethylene phosphonic acid (available under the registered trade mark "Ethrel").
In carrying out said application of a said aqueous solution, said aqueous solution can be applied in any suitable way, e.g. in dispersed form, preferably a spray, and/or said aqueous solution can be poured onto the plant, especially when the plant has a shape that will act as a receptacle for said aqueous solution, e.g. the heart of a pineapple plant.
In testing the present invention, using mature mango plants as test plants, it has been found that said application results in an inductive process to cause in a controlled manner commencement of flowering before normal commencement of flowering would occur, this promotion of flowering being not just breaking of dormancy of preformed flower primordia to advance appearance of flowers.
Application of the present invention to mature mango plants is advantageous, because normal commencement of flowering of mature mango plants is erratic and seasonal.
In testing the present invention, using mature pineapple plants as test plants, it has been found that said application acts to cause in a controlled manner commencement of flowering before normal commencement of flowering would occur.
Application of the present invention to mature pineapple plants is advantageous, because machine harvesting of pineapple fruit requires uniform maturity of fruit at specific harvest dates.
Other plants of commercial interest to which the present invention can be applied are: Eugenia cum in ii, Citrus mitis, Citrus species, Sandoricum koetjape, cashew, guava, grape, acerola, mangosteen, lanzone, orchid, bourgainvilla, hibiscus and azalea.
The earlier flowering provided by said method of the present invention is unlike conventional use of fertilizers, in that fertilizers are applied to soil or leaves so as to produce vegetative growth, and the effect of said applied fertilizers can be delayed and possibly not in the same season.
Conventional nitrogen-fertilization often delays flowering, because that fertilization favours vegetative growth, this favoring being antagonistic to flowering. In contrast to said method of the present invention, other sources of N, P, K, Ca, and Mg, e.g.
urea, calcium phosphate, ammonium sulfate, potassium sulfate, ammonium phosphate, or potassium chloride, did not act to give the earlier flowering when those other sources were sprayed in aqueous solutions onto mature mango plants, mature pineapple plants, and other plants tested.
The present invention will now be illustrated by the followering Examples:
EXAMPLE 1 An aqueous solution of potassium nitrate in a concentration in the range 0.25 to 2.0% w/v was sprayed in December so as to wet mature leaves, dormant leaves, mature flower buds and dormant flower buds of mature mango plants. Flowering of treated plants was thereby caused to commence between 7 to 21 days after that spraying. In contrast, mature mango plants that did not receive said spray did not flower until the following February to March.
In September, mature leaves, dormant leaves, mature flower buds and dormant flower buds of mature pineapple plants were treated by an aqueous solution identical to that used to spray the mango plants. The treatment of the pineapple plants took the form of spraying a portion of the aqueous solution onto some untreated pineapple plants, and the form of pouring a further portion of the aqueous solution into the hearts of other untreated pineapple plants. Flowering of the treated pineapple plants commenced between 70 to 90 days after the treatment. In contrast, mature pineapple plants that did not receive any said treatment had not flowered by that time.
Separate aqueous solutions respectively containing ammonium nitrate, barium nitrate, calcium nitrate, magnesium nitrate, sodium nitrate, and nitric acid, when applied in the same manner and condition as described for the mango plants and pineapple plants mentioned above for the present Example, resulted in earlier flowering of mature mango plants and mature pineapple plants.
EXAMPLE 2
Separate aqueous solutions respectively containing ammonium thiocyanate, barium thiocyanate, calcium thiocyanate, magnesium thiocyanate, potassium thiocyanate and sodium thiocyanate were sprayed in December so as to wet mature leaves, dormant leaves, mature flower buds and dormant flower buds of mature mango plants. The concentrations of these thiocyanates in their respective aqueous solutions were up to 1.5% w/v. Flowering of those treated mature mango plants was thereby caused to commence between 7 to 21 days after that spraying. In contrast, mature mango plants that did not receive said spray did not flower until the following
February to March.
In September, mature leaves, dormant leaves, mature flower buds and dormant flower buds of mature pineapple plants were treated by aqueous solutions identical to those used to spray the mature mango plants of the present Example. The treatment of the pineapple plants took the form of spraying respectively onto some of the pineapple plants portions of said aqueous solutions, each of those plants thereby receiving only a respective one of those portions. Others of the untreated pineapple plants had other respective portions of said aqueous solutions poured into their hearts, each of those plants thereby receiving only a respective one of those portions. Flowering of the treated pineapple plants commenced between 70 to 90 days after said treatments. In contrast, mature pineapple plants that did not receive any said treatment had not flowered by that time. It was found preferable in respect of the treated pineapple plants to use up to substantially 1.0% w/v of the thiocyanates in their said aqueous solutions, as to avoid or reduce risk of leaf burn or the treated pineapple plants.
EXAMPLE 3
An aqueous solution of thiourea and ethylene thiourea, at a total concentration in the range 0.5 to 3.0% w/v (preferably a total concentration of substantially 1.0% w/v), was used in the same manner as described in Example 1 so as to give earlier flowering of mature mango plants and mature pineapple plants.
EXAMPLE 4
Any of the nitrates, thiocyanates, and thioureas described in the preceding
Examples were effective in giving earlier flowering of mature mango and mature pineapple plants, when these compounds were mixed in any number or sequence in aqueous solutions, the total concentrations being in the range 0.1 to 3.0 /O w/v.
EXAMPLE 5
Addition to any of the aqueous solutions of the preceding Examples of (a) sodium naphthalene acetate and naphthalene acetic acid in a total concentration up to 0.1% w/v, (b) 2,4-dichlorophenoxyacetic acid in concentration up to 0.05% w/v, and (c) chloroethylene phosphonic acid in a concentration up to 0.5% w/v, said percentages being based on the final aqueous solutions, improved said earlier flowering of mature mango plants and mature pineapple plants.
