摘要
本文探究辣椒的常温新鲜花粉、常温干燥花粉及干燥冷藏花粉的活力变化,以及3种花粉处理对田间授粉的影响,并应用于淮安红椒两地联合制种,以探究出一个制种效率及制种纯度相对较高的花粉处理方案。结果表明:辣椒花粉活力随着处理时间的延长而降低,常温新鲜花粉活力最高,通过干燥、冷藏的方式,虽然可以有效延长贮藏时间,但花粉活力却受到破坏,不利于提高制种效率及制种纯度。实际生产中,3种花粉相辅相成,共同支撑着制种进程,但应优先使用花粉活力高的常温新鲜花粉及常温干燥花粉,减少干燥冷藏花粉的使用。为保障前2种花粉产量,可将父本定植时间较母本提前20 d,父母本定植比例提升至1∶2.5。
This study explored the vitality changes of fresh pollen at room temperature,dried pollen at room temperature,and dried and refrigerated pollen of peppers,as well as the effects of three pollen treatments on field pollination,and apply them to the joint seed production of red pepper in Huaian to explore a pollen treatment scheme with relatively high seed production efficiency and purity.The results showed that the pollen vitality of peppers decreased with extension of treatment time,and fresh pollen at room temperature had the highest vitality.Although drying and refrigeration could effectively prolong storage time,pollen vitality was damaged,which was not conducive to improving seed production efficiency and purity.In actual production,the three types of pollen complement each other and support the seed production process together.However,priority should be given to using fresh pollen at room temperature and dried pollen at room temperature with high pollen vitality,and the use of dried and refrigerated pollen should be reduced.To ensure the pollen yield of the first two,planting time of the male parent can be advanced by 20 days compared with the female parent,and the planting proportion of can be increased to 1∶2.5.
