Abstract
The invention relates to a method for promoting plant seeds to sprout, and in particular relates to a method for promoting water chestnut seeds to sprout and a used culture medium, belonging to the technical field of biology. The method for promoting the plant seeds to sprout disclosed by the invention comprises the following steps of: immersing, sterilizing and cleaning water chestnut seed teguments after peeling, transferring the obtained seeds on the culture medium, and culturing by illuminating for 8-12h every day under the illumination conditions of 26-30 DEG C and 8000-10000 Lx, wherein the culture cycle is 15-25 d. According to the invention, after the water chestnut seed teguments are peeled and removed, on one hand, the sprouting inhibition effect caused by the teguments can be reduced; on the other hand, the chestnut seeds can absorb moisture rapidly, so that the sprouting requirements are achieved; after the seeds are immersed by warm water, the seed sprouting inhibitors can be obviously reduced; the seeds can sprout easily; furthermore, due to hormone of the culture medium and nutrition supply, the seeds can be promoted to sprout; the survival rate of sprouted seeds is increased; the seed sprouting rate is above 60%; and the survival rate of the sprouted seeds achieves 100%.
Description
Technical field
The present invention relates to a kind of method promoting plant seed germination, particularly relate to the method and used medium that promote water chestnut seed germination, belong to biological technical field.
Background technology
Seed is the distinctive propagulum of plant.But since several thousand, water chestnut is all adopt bulb to breed, and this modes of reproduction is in fact a kind of vegetative propagation, and long-term planting easily causes the degeneration of kind, and this modes of reproduction can not improve kind and upgrade.The problems such as in addition, its disease and pest is serious, and cultivation period is long become increasingly conspicuous, and have had a strong impact on the seed output and quality of water chestnut.Further, Water Chestnuts carries multiple virus disease, and cause water chestnut quality to decline, production rate decline, this exists grave danger to the sound development of water chestnut industry.How to solve the kind sexual involution of bulb, improve water chestnut quality, improve the breeding coefficient of water chestnut, become current water chestnut and produced upper problem in the urgent need to address.
Therefore, adopt seed to study as propagulum, be a brand-new field for water chestnut, breaking through this field will have an immense impact on to water chestnut breeding and industry development.At present, the research that industry is carried out it is considerably less, and this is also determined by water chestnut seed self character, and its form is very tiny, length and width are all less than 1mm, thickness is less than 0.5mm, grows, and wrapped up by outer kind of shell of one deck compact structure in reversed cardioid, be difficult to germinate without process seed, even if the seed after germinateing, be subject to the little impact of endosperm and cause nutrition supply not enough, surviving rate is also very low.Therefore, in the plantation of traditional water chestnut, water chestnut seed is always out in the cold as propagulum, and its excellent heritability can not get embodying.Moreover the substratum of prior art to applicable water chestnut seed germination not yet has research.
Summary of the invention
The object of the present invention is to provide a kind of method and the used medium that promote water chestnut seed germination.The method and substratum used can improve percentage of germination and the surviving rate of water chestnut seed.
For solving above technical problem, the invention provides following technical scheme:
At the substratum promoting to use in the method for water chestnut seed germination, described substratum is made up of MS substratum, 6-BA (6-benzyl aminoadenine), NAA (naphthylacetic acid), sucrose.
Preferably: described often liter of MS substratum adds 0.5-1.0mg6-BA, 0.05-0.1mgNAA, 25g sucrose, and described medium pH is 5.8-6.4.
The method of the promotion water chestnut seed germination utilizing above-mentioned substratum to carry out, comprises the following steps:
1) seed soaking after water chestnut seed shell being peeled off;
2) by step 1) gained seed carries out disinfection and cleans;
3) seed culture: by step 2) gained seed moves to substratum, and under 26-30 DEG C of temperature, 8000-10000Lx illumination condition, illumination every day 8-12h cultivates, and culture cycle is 15-25d.
Preferably: step 1) described seed soaking is until water temperature naturally cools to room temperature in warm water seed being soaked in 50-60 DEG C.
Preferably: step 2) described sterilization comprises alcohol disinfecting and mercuric chloride sterilization, described alcohol disinfecting is by step 1) gained seed be placed in volume fraction be 75% spirituous solution to sterilize 5s, described mercuric chloride sterilization be seed after alcohol disinfecting is placed in volume fraction be 0.1% mercuric chloride solution to sterilize 7-10min.
Preferably: step 2) described cleaning utilizes sterilized water to carry out 6-8 cleaning.
The present invention can reduce kind of shell on the one hand to the inhibition germinateed, make water chestnut seed absorb moisture fast on the other hand, reach the requirement of germination after being peeled off by water chestnut kind shell and removing.Seed, after warm water soaking, can significantly reduce seed germination inhibition, be conducive to seed germination.In addition, hormone in medium and nutrition supply can promote seed germination and improve the seed viability after germinateing.The inventive method operating procedure is simple, equipment investment is few, cost is low, is easy to expand the scale of production.Rate of emergence of the present invention reaches more than the percentage of germination of 60%, and the seed viability after germination reaches 100%.
