| 摘 要： | 对芋组培苗在移栽驯化过程中的生理指标进行了测定, 结果表明: 其叶片叶绿素含量、表观量子产额、羧化效率、净光合速率随驯化时间的延长逐渐增加, 而蒸腾速率和气孔导度则呈下降趋势, 说明移栽驯化可以增强组培苗对环境的适应能力和自养能力。

| Abstract: | The photosynthetic characteristics in taro test-tube plantlets during transplantation and acclimation were measured and analyzed with a TPS-1 photosynthetic system. The results showed that the apparent quantum yield, net photosynthetic rate and carboxylation efficiency of the plantlets increased but the transpiration rate and stomatal conductance decreased during the acclimation after transplantation. The chlorophyll content in leaves of the plantlets also increased substantially. These results indicated that acclimation could greatly improve the capabilities of the plantlets to adapt to natural environment,and enhance their autotrophy. |
