| 摘 要： | 以紫穗槐花粉和柱头为试材,研究和比较了不同方法(醋酸洋红I、2-KI、TTC法、花粉离体培养法)在紫穗槐花粉活力测定上的适用性,并考察了紫穗槐开花前后不同时期花粉活力和柱头可授性的变化。结果表明:0.4%TTC0、.5%TTC法和I2-KI染色法在测定紫穗槐花粉活力上无显著差异,均适用于紫穗槐花粉活力的测定;在开花前1天至开花后第2天,花粉均具有一定活性,其中以开花当天与开花后第1天花粉活力较高;柱头自开花后才具有可授性,并随时间推移逐渐增强,至开花后第2天达到最高,之后下降。

| Abstract: | Four methods,including Magenta acetate method,I2-KI,TTC staining(concentration of 0.3%,0.4%,0.5%) and pollen culture in vitro,were adopted to measure pollen viability of Amorpha fruticosa.After the choosing suitable method,the pollen viability in different time of blossom were mensured.At the same time,the stigma receptivity in different time of flowering was also estimated by benzidine-H2O2 method.The results showed that TTC staining(0.4%,0.5%) and I2-KI staining were no remarkable difference and suitable ... |
