Abstract
The invention discloses a method for improving the germination percentage of European hornbeam seeds. The method comprises the following steps of: processing the European hornbeam seeds in a gibberellic acid (GA3) solution at the concentration of 500-1,000mg/L; dressing the seeds soaked in the gibberellic acid (GA3) by taking wet sand soaked with the gibberellic acid (GA3) solution at the concentration of 500-1,000mg/L as a matrix; and warmly laminating at the constant temperature of between 20 and 25DEG C for 2 to 4 weeks, and cold laminating at the constant temperature of between 3 and 5DEG C for 16 weeks, wherein a seed and sand mixture is frequently turned and stirred and is sprayed with the gibberellic acid (GA3) solution at the concentration of 500-1,000mg/L, and the seeds are ventilated and prevented from being mildewed or rotten. The method has the advantages that the germination percentage of the seeds can be effectively improved, the uniformity of the germination percentage is increased, the method is convenient to implement and easy to promote, the resistance of seedlings of European hornbeam is improved and the method is suitable for production practice.
Description
Technical field
The present invention relates to a kind of method that improves the Carpinus betulus percentage of seedgermination, belong to the forest genetics technical field.
Background technology
The germination rate that improves forest tree seed is one of key content of physiology of seed man both domestic and external and scientific worker's research always.Under field conditions (factors), the percentage of seedgermination of some plants is lower, and this brings many difficulties and inconvenience for inevitably farming, production of forestry, is a great challenge as far as agricultural, afforestation and nursery operator.The seed that germination rate is lower, germination vigor is also low usually, and can occur being short of seedling or emerging irregular phenomenon.Take certain treatment measures to improve germination rate and seeding quality to seed prior to seeding; Be beneficial to and practice thrift the seed consumption; Also promote the seedling primary growth simultaneously; Strengthen the resistance (disease-resistant, drought resisting, cold-resistant, heat resistanceheat resistant) of nursery stock, improve output and the quality of nursery stock, produce for the land for growing field crops and cultivate good nursery stock, solve the seed deficiency and have bigger theoretical direction and practice significance;
Through long term studies and practice, the relevant measure that improves percentage of seedgermination has accumulated suitable rich experience, and the measure that different seeds are taked also is not quite similar, and comprises physical method, lamination processing, HORMONE TREATMENT, chemical method etc. substantially.But seed itself is a very complicated organism, and it is inequality causing the lower reason of different percentages of seedgermination, needs research targetedly.
Summary of the invention
What the present invention proposed is a kind of method that improves the Carpinus betulus percentage of seedgermination, and its purpose is intended to improve the Carpinus betulus seed germination rate, saves the breeding cost, increases economic efficiency.Be China East China, Central China, North China and coastal cities greening and the desirable seeds of afforestation.
Technical solution of the present invention: it is characterized in that this method comprises the steps:
One, in concentration the gibberellin (GA of 500～1000mg/L with the Carpinus betulus seed
3) soaked 24 hours in the solution;
Two, with concentration be the gibberellin (GA of 500～1000mg/L
3) to soak the wet sand of mixing be matrix to solution, and the Carpinus betulus seed after handling through processing step one is dressed seed kind of a husky mixture, wet husky ratio with Carpinus betulus seed volume is 3:1, wet husky water content is 60% of a sand saturation moisture content;
Three, the husky mixture of kind to handling through processing step two places 2～4 weeks of storage under 20～25 ℃ of constant temperatures earlier, and then places 16 weeks of storage under 3～5 ℃ of constant temperatures;
Four, duration of storage whenever stirred kind of husky mixture once at a distance from 3～5 days, and gave the kind gibberellin (GA that husky mixture spray concentration is 500～1000mg/L
3) solution, make wet husky moisture content remain 60% of sand saturation moisture content, and keep the ventilation of Carpinus betulus seed mould rotten grain not occur.
Benefit of the present invention is, Carpinus betulus (Carpinus betulus), tree-like delicate and pretty, quality is fine and smooth, the autumn scenery leaf is golden yellow, is important afforestation seeds, be able to use widely in many countries and regions.Can be used as street tree, garden tree, hedgerow and potted landscape.Simultaneously because of its adaptability more by force, more cold-resistant, happiness calcium, strong, the few damage by disease and insect of wind loading rating, can be China East China, Central China, North China and coastal cities greening and the desirable seeds of afforestation.The present invention can effectively improve the Carpinus betulus seed germination rate, increases the regularity of germination rate, and is easy to operate, is prone to promote, and helps to improve Carpinus betulus seedling resistance, is fit to use in the production practices.
