Effect of Lighting Treatment to Photosythetic Rates in Water Melon

doi:10.7668/hbnxb.2011.05.034

Abstract

Abstract: In the greenhouse,we used Stereo cultivate variety as JieBao to study the influence under different light intensity.The experiment treatment were natural lighting and 50% natural light;detemine plant Pn,Air temperature,blade temperature,PAR,E,Cond,Ci,WUE of leaves.The results show that under 50% natural lighting,watermelon leaves appeared nap a little,but natural light didn′t have.Leaf under 50% natural lighting,its Pn was much less than nater light at 9:00-10:00;but at other times its Pn was similar.

Key words: Jiebao small watermelon, Shading, Pn, Daily variation
