Comparative and Correlation Analysis of Photosynthetic Characteristics of Different Syzygium samarangense Varieties in Blooming Period
摘要
Abstract
The biological traits of leaves as well as photosynthetic characteristics such as chlorophyll contents and chlorophyll fluorescence parameters during blooming period were studied by using four varieties of Syzygium samarangense,including YNDY,TGZH,NS and HJG as test materials under root restriction and dwarf close planting cultivation patterns in greenhouse.The biological characters,chlorophyll contents and chlorophyll fluorescence parameters of leaves at flowering stage and their correlation were analyzed.The results showed that the leaf biological characteristics of YNDY was the best,while those of NS were the worst.The content of chlorophyll a,a+b and a/b of YNDY was highest,while chlorophyll b content of HJG leaf was highest.The differences of real-time Fv'/Fm',qP,qN,and NPQ were smaller among different varieties of Syzygium samarangense,while the differences of ETR were larger.The Fv'/Fm'and ETR of YNDY and TGZH were higher than those of NS and HJG,while their qN and NPQ were opposite.The patterns of the light response curve were consistent among different varieties.The Fv'/Fm'and ETR of YNDY was highest,while those of NS was lowest.There was significant positive correlation between the biological characters of leaves.Chlorophyll a had a negative correlation with chlorophyll b,and a significant positive correlation with chlorophyll a+b,while there was a negative correlation between chlorophyll b and chlorophyll a+b.Chlorophyll a and chlorophyll a+b had a positive correlation with Fv'/Fm',and they had a very significant positive correlation with ETR,while they had a negative correlation with qP,qN and NPQ.Chlorophyll b had a very significant negative correlation with Fv'/Fm',and it had a negative correlation with ETR,while it had a positive correlation with qP,qN and NPQ.Fv'/Fm'had a negative correlation with qP,and a very significant negative correlation with qN and NPQ,while there was a significant positive correlation between Fv'/Fm'and ETR.ETR had a negative correlation with qP,and it had a significant negative correlation with NPQ,while it had a very significant negative correlation with qN.In summary,biological characteristics of YNDY and TGZH leaves were the best,and photosynthetic capacity was stronger.YNDY and TGZH were the suitable Syzygium samarangense varieties under root-limiting and dwarf close cultivation in greenhouse.关键词
