摘　　要：为了了解光合性状对板栗产量的影响,对板栗的光合特性进行研究.通过对不同板栗品种的光合性状测定,探究了板栗光合性状的日变化和光合性状之间的相互关系.结果表明:不同板栗品种光合性状的日变化有一定的差异,并具有相似的变化规律;同时,气孔导度和蒸腾速率因子与光合速率具有显著相关性;光合性状影响光合作用,影响质量.A study was made of the diurnal of the photosynthetic characters in different breeds of Chinese chestnut and of the relationship between them. The results of measuring and analyzing the photosynthetic characters show that there is a difference and also a similar law in their daily change, and that for different breeds, the gas-degree and rate of photosynthesis bear a significant relevance to the transpiration rate factors.
