低温胁迫下7种木麻黄变异类型抗寒性的比较
Comparision of cold resistance characteristics in 7 variations of Casuarina equisetifolia
摘要
Abstract
The test was conducted on the changes of chlorophyll fluorescence characteristics in leaves of 7 variations of Casuarina equisetifolia from Big Deer Islands in Zhejiang, before and after a natural low temperature stress. The results showed that each variation had displayed different adaptabilities. R5 showed the strongest cold resistance with its greatest actual photochemistry quantum yield for PS Ⅱ which indicated the most powerful photosynthesis efficiency. Fv/Fm of G7 dropped most with the relatively weakest photosynthetic efficiency and cold resistance, as for cold resistance of the rest 5 variations were moderate. The qN of each variation had gotten different degrees of increase under the low temperature stress, which reacted diversities of the photosynthetic mechanisms for low temperature resistance damage.关键词
