摘要: 根据两年的田间试验资料,分析了不同光质和光强对酿酒葡萄光合速率及糖分积累的影响。结果表明:不同光质对酿酒葡萄光合作用有显著影响。在光强较弱的时候,彩色薄膜覆盖有促进葡萄光合作用的效果。光合速率随光强增大而增大,上午各处理间的差异较大,午后这种差异逐渐减小。一定范围内光照强度对葡萄糖分积累有影响,且光强越大糖分积累越高,光照减弱后糖分积累降低。彩色膜覆盖对葡萄糖分积累也有一定影响,多数会使葡萄糖分积累减少。

Abstract: The field experiments on wine grape in Ningxia Autonomous Region during 2004 and 2005 were conducted to determine impacts of the different light intensities and qualities on photosynthesis and sugar accumulation of wine grape.The results showed that the light quality had a remarkable effect on the net photosynthesis of wine grape.The photosynthesis of wine grape covered with color film was enhanced when the light was weak.The net photosynthesis of wine grape increased with the increasing of the light intensity.The difference of various treatments was big in the morning and reduced afternoon.The light intensity affected the sugar accumulation to some extent.The sugar accumulation increased with the increasing of the light intensity.The sugar accumulation could be influenced and mainly reduced by color film covering.

Key words: Light condition, Light condition, Wine grape, Net photosynthesis, Sugar accumulation
