玉米幼苗叶片叶绿素荧光参数变化规律研究
Characteristics of Chlorophyll Fluorescence Parameters of Leaves during Leaf Elongation of Maize Seedling
摘要
Abstract
The characteristics of chlorophyll fluorescence parameters in the apex,centre and base of leaf during leaf elongation in maize seedling were investigated through determination of chlorophyll fluorescence induction dynamics of leaves during leaf elongation of maize seedling with Handy-PEA to ascertain the variation characteristics of photochemical activity in leaf development process of C4 plants. The results showed that Fo decreased with 5% degree and Fv/Fo and Fv/Fm increased gradually from 2. 59 and 0. 76 to 3. 92 and 0. 82 respectively in the leaf apex during leaf elongation from 2 cm to 30cm,while Fv was lowest and ABS/RC,Tro/RC,Eto/RC and Dio/RC were highest in 2 cm length leaf. The variation of characteristics of chlorophyll fluorescence parameters from the base to apex of 30 cm length leaf coincided with that in the leaf apex during leaf elongation. These results stated that the photochemical function in the part from base to apex of leaf improved gradually during leaf elongation in maize seedling.关键词
