摘　　要：以黄蜀葵为研究对象,对各月的全天荧光参数进行观测,研究秋季的季节性干旱对其叶片叶绿素荧光特性的影响。结果表明:全天的任意时刻的初始荧光Fo值均为9月>10月>11月;全天的Fm值和Fv/Fm值,10月与11月变化趋势基本相近。方差分析结果表明,秋季不同月份、时刻均对黄蜀葵的荧光指标有显著影响(P<0.05),月份与时刻之间存在交互作用且对黄蜀葵的荧光特性也有显著影响(P<0.05)。Controlled experiments were conducted to investigate the effect of seasonal drought in autumn on chlorophyll fluorescence characteristics variation of Abelnoschus manihot leaves by observing fluorescence parameters in the whole day of months.The results showed that,the Fo values of any time throughout a day in September were bigger than the ones in October ,and the ones in November were the smallest;trends of Fm values and Fv/Fm values in October and November are similar to each other.The results of variance a-nalysis showed that month ,time and their interaction significantly affected chlorophyll fluorescence characteristics variation of Abel-noschus manihot leaves （ P〈0.05 ）.
