不同品种蓖麻花粉生活力特性的研究

以中北3号、金长城5号、汾蓖1号、秀蓖1号四个蓖麻品种为材料,研究蓖麻花粉萌发能力与温度、贮藏湿度及采集时间的相关性,结果表明：最适宜蓖麻花粉萌发的温度为30～35℃,花粉萌发率达到75.12％～80.24％;一天中蓖麻花粉萌发能力最强的时间为8：00～14：00时,花粉萌发率达到81.35％～90.18％;蓖麻花粉收集、贮藏的最适温度为45％～55％,花粉萌发率在84.03％～88.01％.

Study on the Characteristics of Pollen Viability in Different Varieties of Ricinus communis

Taking four varieties of Ricinus communis that were Zhongbei No.3, Jinchangcheng No.5, Fenbi No.1 and Xiubi No.1 as materials to research the correlation between pollen viability with temperature, storage humidity and acquisition time, the results showed that the most suitable temperature for castor pollen germination was 30-35%, and the pollen germination rate reached 75.12%-80.24%; The strongest time of pollen germination in one day was in 8：00 to 14：00, and the pollen germination rate reached 81.35%-90.18%; The optimum humidity for pollen collection and storage was 45%-55%, and the pollen germination rate reached 84.03%-88.01%.
