Abstract
The invention provides a method for breaking dormancy of Carex stenophylloides seeds, which comprises the steps of seed picking followed by concentrated sulfuric acid treatment and sand storage. The method for breaking dormancy of Carex stenophylloides seeds solves the problem that seeds do not germinate. Germination ends after 16 days, and the final germination rate is 88.7%.
Description
Technical field
The present invention relates to Central Asia sedge (Carex stenophylloides) seed methods for breaking dormancy.Specifically be Central Asia sedge seed through after selected again the concentrated sulfuric acid handle, break seed dormancy through this method, solve the ablastous problem of seed.Belong to agricultural biological technical field.
Background technology
Central Asia sedge (Carex stenophylloides) sedge belongs to herbaceos perennial, has another name called the gravel sedge, is distributed widely in China northeast, North China, northwest, all provinces and regions, southwest.Grow in sandy and gravel matter grassland, saline meadow.Turn green spring early, the dark green phase is long, plant is short, plant type is graceful, cover fast, the anti-trample of procreation, can be feeding, be a kind of up-and-coming northern lawn greening plant.But sedge sexual propagation power in the Central Asia is weak, seed production is low, have the dormancy phenomenon.Because of can't solving the planting seed problem, lawn planting (Li Qingfeng etc., the gravel sedge grows and the research of seed industry characteristics, the meadow science) still can not be come with Central Asia sedge seed sowing mode in various places so far.Sedge belongs to seed not of the same race and differs greatly, and 3 types of not dormancy, shallow dormancy and deep dormancies are arranged, and Central Asia sedge belongs to deep dormancy, and its breeding research is less, and the research of seed methods for breaking dormancy does not appear in the newspapers both at home and abroad.
Summary of the invention
The objective of the invention is to set up Central Asia sedge seed methods for breaking dormancy.
Content of the present invention comprises that the Central Asia sedge seed concentrated sulfuric acid is handled, the husky Tibetan treatment temperature and time.
The Central Asia of the present invention sedge seed methods for breaking dormancy, it is neat to germinate, and shortens germinating time, and germination rate is high.
The present invention breaks the seed dormant method of Central Asia sedge and comprises: (1) Central Asia sedge seed concentrated sulfuric acid processing time is: A.0s; B.5s; C.10s; D.15s; (2) the husky temperature and time of hiding of seed selects one of which below being: ℃ storage 30-60d A.4-10; B.15-20 ℃ storage 10-20d; C.25-30 ℃ storage 0-15d.
The present invention to Central Asia sedge seed cleaning after, handle through the concentrated sulfuric acid, after the embryo suction is expanded, plant the increase of passing through property of skin, shorten germinating time, improve percentage of seedgermination.
The scheme of technical solution problem of the present invention divides following three steps to accomplish:
(1) Central Asia sedge seed collection, air-dry after, take by weighing the 10g seed, be soaked in the large beaker of filled with water, beaker places 20-25 ℃ climatic cabinate.Every at a distance from 1h stirring 1 time, take off heavy seed behind the 24h.
(2) the sinking seed of the 1st step being obtained blots surface moisture, places four small beakers respectively, adds the concentrated sulfuric acid and soaks, and soak time is: 0s, 5s, 10s, 15s.Constantly stir between soak period, soak the completion water and rinse well.
(3) handle that the back seed is husky ensconces in the insulating box, the husky temperature of hiding of control is regularly taken out seed and in climatic cabinate, is done germination test, and day temperature of germinateing/night temperature is 25 ℃/15 ℃, daily check seed, statistics germination rate.
The advantage of the inventive method is Central Asia sedge through the concentrated sulfuric acid, plants the increase of passing through property of skin, after husky Tibetan fully absorbs water, improves percentage of seedgermination, shortens germinating time, is not germinateed by original dormancy, brings up to germination rate more than 80%, has effectively broken seed dormancy.
