摘要
齐单1号制种在授粉后49-67 d间收获,种子活力高;在春季低温冷凉区制种,建议在授粉后55-61 d收获;一年繁多年用的种子,应在授粉49-58 d收获;在逆境、条件复杂区制种,应在授粉55-67 d收获,以保持种子较好的活力和幼苗生长量。
Harvesting Qidan 1 after artificial pollinating for 49 - 67 days,the vigor of seeds was the highest.When breeding in cold area with low temperature in spring,it was suggested to harvest seeds after artificial pollinating for 55 - 61 days.The seeds which would be used for several years should be harvested after artificial pollinating for 49 - 58 days.When breeding under adverse and complex situations,it was suggested to harvest after artificial pollinating for 55 - 67 days to maintain good seed vigor and seedling growth.
