鲁梅克斯K-1杂交酸模传粉生物学研究

Study on Pollination Biology in Rumex patientia ×R. tianscha nicus cv.Rumex K-1

利用去雄、套袋、人工授粉方法研究不同授粉方式和授粉时间对鲁梅克斯K-1杂交酸模结实率的影响。结果表明,鲁梅克斯K-1杂交酸模自花授粉、异花授粉都能正常结实,结实率达95%以上。异花授粉最佳时间为花开放后1~6 h。花粉量大。风媒传粉,未见昆虫访问。

Rumex k-1＇s pollination habit is researched by castrating and covering with sack and manual pollination.The result showed that Rumex k-1 can produce seed normally by either self pollination or cross pollination,the setting rate is more 95%.The best time of cross pollination is 1-6 hour after blooming.The quantity of pollen is larger.The pollens are spreader by wind,not by insect.
