| 摘 要： | 研究了低温弱光条件对番茄苗期植株茎的长度、叶面积、根系活力、功能叶片叶绿素含量及净光合速率的影响。结果表明 :低温弱光造成番茄茎的增长和叶面积扩展减缓、叶片净光合速率降低 ,但对番茄根系活力影响不明显 ;低温逆境对于番茄茎叶生长及净光合速率的影响作用比弱光逆境更大 ;不同品种受低温弱光逆境影响的程度不同

| Abstract: | Influences of low temperature and poor light on growth and photosynthesis of tomato (Lycopersicon esculentum Mill.) seedling were studied in phytotron. Results showed that the increment of stem length,leaf expanding and net photosynthesis rate were reduced under the stress of low temperautre and poor light,but root vigor was not significantly influenced by the stress. The influence of low temperature was more significant than poor light stress. The responses were different between varieties. |
