高温与生长调节物质对辣椒花粉生活力的影响

研究表明，３５℃以上的短时（１０ｍｉｎ）高温，可使辣椒花粉的生活力明显下降；高温处理花朵时，花粉的致死温度为５４℃，直接处理花粉时，致死温度为４３℃；目前生产上应用的２，４－Ｄ等５种植物生长调节物质均对辣椒花粉的生活力具有明显的抑制作用。

Effects of High Temperature and the Plant Growth Regulating Materials on the Viability of the Bollens in Hot Pepper

The results of this study indicate that high temperature in short time(10 min),above 35℃ can obviously reduce the pollen viability of hot pepper,the five widely used plant growth regulating materials,such as 2,4-D,greatly inhibit the pollen viability.When the flowers of hot pepper are exposed to the high temperature,the thermal death point of the pollen is 54℃.When the pollens are directly exposed to the high temperature,the thermal death point of the pollens is 43℃.
