| 摘 要： | 研究了偏低温弱光条件对两个辣椒品种株高、茎粗和根系等生长发育状况,以及叶面积、叶片中叶绿素含量和净光合速率影响,研究结果表明:低温弱光胁迫使辣椒株高和茎粗增长及叶面积扩展变慢,但低温对植株生长的抑制作用比弱光更明显;低温弱光下辣椒植株根系活力下降;低温弱光胁迫下,叶片中叶绿素含量下降,净光合速率下降。

| Abstract: | Effects of low temperature and poor light on growth and photosynthesis in two pepper cultivars were studied.The re-sults showed,soaked seeds by treatment,stress of low temperature and poor light increased plant high and stem diameter,re-duced expanding speed of leaf area.But action of low temperature is more significant than poor light.Meanwhile,low tempera-ture and poor light reduced root vigor,the net photosynthetic rate and chlorophyll content. |
