| 摘 要： | 在温室中研究了La3+对UV-C辐射胁迫下番茄幼苗光合色素含量的影响。结果表明:La3+能够显著缓解UV-C辐射胁迫对光合色素的降解作用,与单一UV-C胁迫组相比,番茄幼苗叶绿素a平均提高了17.65%、叶绿素b平均提高了17.11%;La3+可以缓解类胡萝卜素在UV-C胁迫下的降解,使其维持较高水平。综合比较得出,30mg/LLaCl3在UV-C辐射胁迫下对番茄幼苗的防护效果好于60mg/LLaCl3。

| Abstract: | The effects of La3+ on the chlorophyll content in tomato seedlings were examined under UV-C radiation stress in greenhouse.The results showed that La3+ could significantly relieve the degradation effect of chlorophyll stressed by UV-C radiation.Compared with the single UV-C stress group,chlorophylla increased 17.65% by La3+ averagely,chlorophyll b 17.11% and La3+ could relieve the carotenoid degradation in tomato seedling under UV-C radiation stress to keep carotenoid content in tomato seedlings maintained ... |
