测定花粉生活力的方法很多,其中离体萌发试验是比较常用的。观介绍二种方法。1、悬滴法:首先配制好培养基备用。可任选一二种:①蔗糖液:配成10～30%。不同植物不同。如玉米15%,甜菜30%。在蔗糖液中再加入0.01%硼酸效果更好。②混合液:4%蔗糖,0.1%氯化钙,0.01%的硼酸。这种培养液、因除蔗糖外,还 There are many ways to determine pollen viability, of which in vitro germination tests are more commonly used. Introduce two methods. 1, hanging drop method: first prepared a good medium for use. One or two optional: ① sucrose solution: dubbed 10 to 30%. Different plants different. Such as 15% of corn, sugar beet 30%. Adding 0.01% boric acid in sucrose solution is better. ② mixture: 4% sucrose, 0.1% calcium chloride, 0.01% boric acid. This culture medium, in addition to sucrose, but also
