There was a little difference betweenphotosynthesis characteristic of the two varieties,response of Jiamusi to low temperature andpoor light was more sensitive than that of Longjiao No.2 and decreased pronouncedly withdecreasing light.6.EC and MDA of pepper leaves increased under low temperature and poor light,therewere no significant differences between them with decreasing light at 21-23℃/8-10℃,butthey were increased dramatically at 15-20℃/5-6℃.So we can speculate that lowertemperature was the direct reason resulted in cell membrane lipid peroxidation.7.No significant difference of SOD activity was observed under suboptimal temperatureand poor light21-23℃/8-10℃;150μmol·m~(-2·s~(-1),but SOD and POD activity substantiallydeclined with lowering temperature and light as well as treatment time.8.Under suboptimal temperature and lower light,proline accumulated to increaseosmotic regulation capacity and alleviate chilling damage.Soluble carbohydrate of pepper leaves decreased progressively and significantly with decreasing temperature and lightintensity as well as longer treatment time.So we think that synthesis and transport ofphotosynthetic product were inhibited by low temperature and poor light as solublecarbohydrate was important component of photosynthetic product.

两个供试辣椒品种之间的光合特性略有差异，佳木斯对低温弱光的反应比陇椒2号敏感，尤其随光照降低，其光合作用显著降低。6、低温弱光胁迫下，辣椒叶片的相对电导率和丙二醛含量都有不同程度的提高，在偏低温下，随着光照减弱，相对电导率和丙二醛含量差异不显著；在极端低温下，随着光照进一步减弱，相对电导率和丙二醛含量明显提高，随着处理时间延长，同一温度下，随着光照降低，叶片丙二醛含量也显著增加，由此可初步判断，低温是导致细胞膜脂过氧化的直接原因。7、经偏低温较弱光21～23℃／8～10℃、150μmol·m~(-2·s~(-1)处理后，辣椒叶片的超氧化物歧化酶活性变化与对照无显著差异，但随着温度、光强的逐步降低和处理时间的延长，SOD、POD活性显著降低。8、在偏低温较弱光下，辣椒能积累更多的脯氨酸，增强渗透调节，减轻低温冷害。
