Abstract
The invention discloses a method for increasing the germination rate of seeds of euscaphis japonica serving as ornamental woody plants, and relates to the technical field of plant cultivation. The method comprises the steps of paving the euscaphis japonica seeds on a hot flat iron pot at the highest speed for 5 seconds, pouring the euscaphis japonica seeds into clear water immediately for cooling, transferring the seeds into 50-350mg/L gibberellin 920 solution with the volume which is five times larger than the seeds for immersion for 6 hours, and taking out the seeds for sowing. The method disclosed by the invention is safe and economical; the germination rate of the seeds of the euscaphis japonica is increased to over 100 percent on the basis of the original germination rate, and important significance for the multiplication and the popularization application of euscaphis japonica materials is achieved.
Description
Technical field
The present invention relates to field of plant growing technology, in particular a kind of method that improves the wild crow Chinese toon of ornamencal flower and tree percentage of seedgermination.
Background technology
Wild crow Chinese toon (Euscaphis japonica), for defoliation small arbor or the shrub of the wild crow Toona of Staphyleaceae, is a kind of ornamental plants that has very much the potentiality utilized.This seed has the characteristic of deep-sleep, as is left intact, and seed could be sprouted or do not sprouted after 2 years, and germination rate is extremely low.The investigation of wild wild crow Chinese toon population is found, wild crow Chinese toon is all present in border, barren hill, Xi Bian group with individual plant form, has no seedling near plant.Although someone sporadicly inquired into the method for wild crow Chinese toon vernalization processing, as Qi Zhenxiong (2012) takes the high water temperature heat facture that rises, make the seed germination time do sth. in advance 1 year; Yang Yanling (2008) and Chen Biliang (2006) find that high temperature vernalization (seed soaking water temperature 65-70 DEG C) ﹑ wet-storage, the vernalization of low temperature lamination etc. all can improve percentage of seedgermination; Chen Cuili (2012) uses the concentrated sulfuric acid of white wine and 95% to process wild crow Chinese toon seed, has certain vernalization effect.But be which kind of or which kind reason causes seed dormancy not do comprehensive system research, the method specific aim of processing is not strong actually.
The broken dormant technology of seed just has one of On Comprehensive Technique of vernalization in the species seedling culture of dormancy habit, and the broken dormant technology of the wild crow Chinese toon of existing research exists one-sidedness, lacks supporting technical system research; Require height and treatment people professional standards to require high defect to treatment conditions, be limited in laboratory and complete, technology is restricted to applying of production field.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existing in the wild crow Chinese toon percentage of seedgermination of raising for prior art, and a kind of method that improves the wild crow Chinese toon of ornamencal flower and tree percentage of seedgermination is provided.
Technical scheme of the present invention is as follows:
A kind of method that improves the wild crow Chinese toon of ornamencal flower and tree percentage of seedgermination, that wild crow Chinese toon seed is laid in and is burnt on red dull and stereotyped iron pan after 5 seconds with the fastest speed, pour in clear water and lower the temperature at once, then seed is proceeded in the gibberellin 920 solution of 50mg/L～350mg/L of 5 times of volumes of seed and soak 6 hours, rear taking-up sowing.
The concentration of described gibberellin 920 solution, is preferably 150mg/L.
Method safety of the present invention is economical again, and wild crow Chinese toon percentage of seedgermination is brought up to the more than 100% of former germination rate, has important function to the expansion of wild crow Chinese toon material is numerous with applying.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment 1
For the mechanical obstacles of kind of shell, take the method for localized hyperthermia's charing, seed is divided into 3 parts, 300 every part, be laid in respectively to burn on red dull and stereotyped iron pan and take out after static 5 seconds, 10 seconds and 15 seconds, put into immediately the cold water broken shell of lowering the temperature, destroy the mechanical obstacles effect of kind of shell.The local charing of high temperature process after sowing, result shows, the percentage of seedgermination of processing 5 seconds reaches 16%-18%, embryo does not come to harm, and the seed of processing 10 seconds and 15 seconds does not all germinate, the embryo necrosis of turning black.
To the existence of endogenous inhibiting substances, select 1200 seeds, by after seed broken shell, be divided into 300 portions, after soaking seed respectively 6 hours by the concentration that the gibberellin 920 that Shanghai Tongrui Biotechnology Co., Ltd. produces is made into 50mg//L, 150mg/L, 250mg/L, 350mg/L, take out, sowing, result shows, the germination rate of 4 processing is followed successively by 34%, 42%, 37%, 31%, wherein the highest with the germination rate of 150mg/L, reach 42%, can greatly improve as seen the germination rate of wild crow Chinese toon seed by the combination of above-mentioned 2 kinds of methods.
Embodiment 2
On October 3rd, 2013, carry out wild crow Chinese toon seeding and seedling raising at wild plant domestication center, Tian Kai gardens, sweet osmanthus town, Pengzhou City, Sichuan Province, first select physical features mild, soil layer is deep loose, well-drained sandy loam soil is as our nursery, and soil process is turned over, smooth, apply fertilizer to the subsoil (0.5 kilogram/square meter fused calcium magnesium phosphate fully mixes with topsoil), sterilization (500 times of liquid pourings of carbendazim) preparation.The wild crow Chinese toon seed of collecting is pressed to 2000 1 part, be divided into 3 parts, after 0.1% disinfecting solution of potassium permanganate, after adopting respectively following 3 kinds of processing modes, sow, 1. without other pretreatment, the seed directly soaking in clear water takes out sowing (volume of clear water is 5 times of seed volume) after 6 hours.2. adopt the local charing skin breaking of high temperature method, seed is laid in and is burnt on red dull and stereotyped iron pan after 5 seconds with the fastest speed, pour at once in clear water and lower the temperature 2 minutes, proceed to soak in the clear water of 5 times of seed volumes and after 6 hours, take out sowing.3. local charing broken shell+150mg/L gibberellin 920 (Shanghai Tongrui Biotechnology Co., Ltd.'s production) the solution immersion treatment of high temperature, seed is pressed to method 2., by seed after the high temperature skin breaking of 5 seconds, in clear water, lower the temperature, then proceed to soak in the 150mg/L920 solution of 5 times of volumes of seed and after 6 hours, take out sowing.Seed uniform broadcasting, in seedbed, is processed sowing 2.0 square meters for every kind, after planting covers one deck 0.5-0.7 centimetre of thin sand, waters enough water with watering can.Build plastic greenhouse heat and moisture preserving, on seedbed, cover again the pine needle that 0.1cm is thick winter.Within every 5-7 days, check a seedbed, observe on November 24th, 2013 and find that 3. the plant and process seed and have sprouting phenomenon.On December 30th, 2013,2. the plant to process and have seed germination, 1. planting processing seed on February 27th, 2014 starts to sprout, the emergence rate of 3 kinds of processing of statistics on March 25, result shows that germination rate is followed successively by 9%, 15% and 45%, wherein the local charing broken shell+150mg/L of high temperature gibberellin 920 solution soaks that within 6 hours, to process germination rate the highest, and 3. the plant seed germinating time after treatment and 2. plant and process early than the, and 1. the plant that to process seed sprouting the slowest.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
