| 摘 要： | 以抗虫转基因欧洲黑杨和非转基因欧洲黑杨无性系对照为研究材料,比较研究了其扦插苗在盆栽条件下苗期的光合生理特性及叶绿素荧光特性的差异,目的是了解外源基因的导入是否对欧洲黑杨的光合作用产生了非预期效应.结果表明:除了Ci和Fv/Fm外,转基因欧洲黑杨和对照在其他光合指标间差异均未达到显著水平.转基因欧洲黑杨和对照的净光合速...

| Abstract: | Photosynthetic and chlorophyll fluorescence characteristics of transgenic Bt Populus nigra seedlings were studied to discover whether there were unexpected effects of exogenous genes on photosynthesis of transgenic P.nigra.The results revealed that transgenic and non-transgenic P.nigra showed no statistically significant differences in photosynthetic parameters except for Intercellular CO2 concentration (Ci) and photochemical efficiency (Fv /Fm).The diurnal fluctuation of net photosynthetic rates of both tr... |
