摘要
1988～1989年在田间条件下对燕麦叶片表观光合速率为主的光合性能进行了初步的研究。对不同叶位的叶片、不同生育时期、单叶伸展过程的光合性能,以及光合速率的日变化进行了测定比较。并对有关光合性能与光强、气温及相对湿度等生态因子的关系进行了测定和分析。
The photosynthetic characteristics,such as net photosynthetic rate (NPR),of leaf blades,wer studied preliminarily in field-grown oats during 1988 and 1989 growing periods.Determination and comparison of the photosynthe- tic characteristics,of leaf blades at different positions on the main stem,during various growth stages,and in the process of elongation and expansion of a single leaf,as well as the diurnal changes of NPR,were cunducted respectively. In addition,the relations between the photosynthetic characteri stics and the ecological factors (light intensity,air temperature,relative humidity,etc) were derminated and discussed.
