摘  要:
以3种形态差异较大的君子兰栽培品种(大胜利、日本兰、金丝兰)为试材,利用CIR-AS-2便携式光合仪,对其光合特性进行比较研究。结果表明:君子兰净光合速率日变化为典型的单峰曲线,最高峰值出现在10:30左右。君子兰光补偿点为21~45μmol.m-2.s-1,光饱和点为380~420μmol.mol-1,CO2饱和点为740~830μmol.mol-1,3个品种间各项光合指标差异较小,君子兰光合作用对温度适应范围在13.5~37.5℃之间,最适温度在26~32℃之间。

摘  要:
The photosynthetic characteristics of three Clivia,were studied,using the CIRAS-2 photosynthetic instrument.The results showed that Clivia net photosynthetic rate(Pn)diurnal variation of a typical single-peak curve,the peak value occurs at about 10:30 in the morning.Clivia light compensation point(LCP)for the 21~45 μmol·m-2·s-1,light saturation point(LSP)for the 380~420 μmol·mol-1,CO2 saturation point(CSP)for the 740~830 μmol·mol-1.The three species of photosynthetic indicators of differences between the smaller,Clivia photosynthetic adaptation to temperature range of between 13.5~37.5℃,and the optimum temperature between 26~32℃.
