Comparative analysis on the photosynthetic performances and chlorophyll fluorescence characteristics among lines of Dendranthema indicum var.aromaticum
摘要
Abstract
Three superior lines of Dendranthema indicum var.aromaticum (S1401,S1407 and S1415)successfully introduced and cultivated in a nursery of this college were used as test materials,and their difference in photosynthetic performance and adaptability to different light environments were comparatively analyzed by using the portable Li-6400 XT photosynthesis measuring system.The results showed that (1) in terms of diurnal variation of photosynthetic rate,S1407 presented a double-hump curve and S1401 and S1415 a unimodal curve;The 3 lines' difference was less in light compensation point,and in light saturation point S1451 was the highest and S1401 the lowest;The descending order of ability to utilize strong light was S1415 ＞ S1407 ＞ S1401,and S1415 had the widest light adaptation range.(2) In terms of fluorescence parameters,the order of 3 lines was S1407 ＞ S1415 ＞ S1401 in initial fluorescence Fo values and S1401 ＞ S1407 ＞ S1415 in PhiPS2,qP and ETR values,and the non-photochemical quenching coefficient of S1401 was 0.83,being the smallest.The photosynthetic system of S1401 had the weakest self-protection ability.关键词
