Scirpus planiculmis seed dormancy breaking method

Abstract

The invention relates to a scirpus planiculmis seed dormancy breaking method for solving the problems of dormancy phenomenon, long seedling emergence period and low germination percentage of scirpus planiculmis seeds. The method disclosed by the invention comprises the three steps of seed collection, clear water immersion and sterilization, and cold storage treatment. By using the scirpus planiculmis seed dormancy breaking method, the dormancy period of scirpus planiculmis seeds is shortened from 9-10 months to about 150 days under natural conditions, and the germination rate is increased to 83%; in addition, the scirpus planiculmis seed dormancy breaking method is simple in operation and low in cost and is used for the practical vegetation recovery work.

Description

technical field

[0001] The invention relates to a method for breaking the dormancy of the seeds of the syringa chinensis. Background technique

[0002] Cyperus is a perennial herbaceous plant of Cyperaceae, which mainly grows in swamps and shallow waters. In the Momoge Wetland of the Songnen Plain, the flat stalk is the main food source plant of the endangered species in the world, the Siberian Crane; the number of Siberian Cranes that stop here every spring and autumn reaches more than 3,000, accounting for 75% of the total number in the world ( Yang Bingbing, Yu Guohai, Sun Xiaowei, Zou Changlin, Wang Bo, Wang Yong. Bird resources in Jilin Momoge National Nature Reserve. Journal of Zoology, 2006,41(6):82-91.), therefore, The area and growth status of the Siberian scutellaria population in this area are closely related to the fate of Siberian cranes. However, due to the influence of climate change and human activities, the habitat of Siberian chinensis has been severely d...

[0011] Specific implementation mode one: a method for breaking the dormancy of the seeds of Siamia scutellaria in this specific implementation mode, specifically comprises the following steps:

[0012] (1) Collect the mature stalk grass seeds, remove impurities and shrunken seeds, and air-dry them in a cool and dry place indoors to ensure that the moisture content of the seeds is 6.7% to 7.3%;

[0013] (2) Soak the air-dried seeds with distilled water until the seed coat is softened at normal temperature; soak and disinfect the soaked seeds with medical ethanol solution, rinse them with sterile water after disinfection;

[0014] (3) Put the seeds treated in step (2) into a plastic cup, add sterile water, store at -16°C to 4°C for 60 to 150 days, and break the seed dormancy.

[0015] Specific embodiment 2: In this specific embodiment, a method for breaking the dormancy of the seeds of Siamia spp. is different from the specific embodiment 1 in that in step (2), the air-dried seeds are soaked in distilled water for 2 hours at 20°C . Others are the same as the first embodiment.
