在生产实践中,油菜新收获的种子,特别是在低温阴雨条件下成熟的新鲜种子,往往发芽率甚低,这是由于油菜种子多处于休眠状态,其休眠主要原因是种子尚未完成后熟作用、种皮透气透水性差,这样在选种入库,引种与调运种子吋,就不能凭常规发芽法去淘汰劣种。据此本文试图研究油菜新收种子的休眠情况以及相应的破眠方法,旨在探索出一套简便有效、结果准确的检验方法,以便在短期内弄清待测种子的真实发芽能力。 In production practice, rapeseed newly harvested seeds, especially fresh seeds matured under low temperature and rainy conditions, often have very low germination rates due to the dormancy of rapeseed seeds mostly due to the dormancy of the seeds that have not yet been completed , Seed coat breathable water permeability is poor, so in the selection of storage, introduction and deployment of seeds, you can not use conventional germination method to eliminate inferior species. Based on this, this paper attempts to study the dormancy status of napus newly-harvested seeds and corresponding methods of hypnosis, aiming at exploring a simple, effective and accurate test method in order to find out the true germination ability of tested seeds in a short period of time.
