对半野生、半栽培及栽培大豆叶片某些光合特性指标的比较研究表明,半野生大豆、半栽培大豆和栽培大豆叶面积指数依次降低,而比叶重、叶绿素含量和净光合速率均表现为随品种的进化而增加;从生育期的变化来看,3种类型大豆叶片比叶重和叶绿素含量变化基本一致,苗期和结荚期较低,开花期较高,最大值出现在鼓粒期;3种类型大豆的光合日变化都呈“双峰”曲线型变化,但以栽培大豆日变化最为明显。
Comparative studies on some photosynthetic characteristics of semi-wild, semi-cultivated and cultivated soybean leaves showed that the leaf area index of semi-wild soybean, semi-cultivated soybean and cultivated soybean decreased in turn while the specific leaf weight, chlorophyll content and net photosynthetic rate With the evolution of varieties increased; changes from the growth stage, the three types of soybean leaf weight and chlorophyll content changes are basically the same, the seedling stage and the pod stage lower flowering period, the maximum appears in the drum grain The photosynthetic diurnal changes of the three types of soybean showed a “bimodal” curve pattern, but the most obvious change was in cultivated soybean.
