以4种不同起源地的辣椒为供试材料，研究不同低温弱光条件下辣椒幼苗光合特性的差异。结果表明，随着温度和光照强度的不断降低，4种不同起源地辣椒幼苗的光合参数和叶绿素荧光参数大致呈下降趋势。这充分说明，低温弱光胁迫可能通过直接降低光合机构的活性，使PSⅡ反应中心遭受破坏来影响辣椒幼苗的光合作用的。另外，在低温弱光下起源于土耳其的材料20805表现出更好的弱光利用能力和更高的光化学效率，而起源于中国长江三角洲地区的材料07-1-10-1--2则最差。这说明，低温弱光下辣椒幼苗的光合特性差异可能与起源地的气候不同有关。

Under different low temperature and poor light treatment , the photosynthetic characteristics of four different origin pepper were studied .The results showed that with falling temperature and light intensity , photosynthetic pa-rameters and chlorophyll fluorescence parameters of four different origin pepper substantially decreased .These results indicated that low temperature and poor light affected the photosynthesis of pepper seedlings by directly reducing the activity of the photosynthetic tissue and destroying PSⅡreaction center.Besides, material 20805 originated in Tur-key showed better low light utilization ability and stronger photochemical efficiency , material 07-1-1-0-1-2 originated in the Yangtze River Delta region of China was the worst .It could be speculated that under low temperature and poor light, differences in photosynthetic characteristics of pepper seedlings might be due to the difference in the climate of pepper origin .
