干旱胁迫对小麦代换系叶绿素荧光参数的影响及染色体效应初步分析
Effect and Preliminary Analysis of Chromosomal Control on the Chlorophyll Fluorescence Parameters of Wheat Substitution Lines Between Synthetic Hexaploid Wheat and Chinese Spring Under Drought Stress
摘要
Abstract
[Objective] Chromosomesubstitution lines between Chinese Spring and synthetic hexaploid wheat(CS-Synthetic 6x) were used to study the regulation effect of foreign added chromosome on chlorophyll fluorescence parameters under drought stress. [Method] The chlorophyll fluorescence parameters, including Fo, Fm, Fv/Fm and Fv/Fo in flag leaves at different developing stages in different water treatments were measured during 2005-2007. [Result] The results showed that Fm and Fo of 5B substitution line were significantly different from Chinese Spring in the control treatment. Drought stress resulted in inhibition of PS Ⅱ photochemical activity and reduction of Fm, Fv/Fm, Fv/Fo as well as accumulation of Fo; Fo of 3A substitution line and Fm of 4D substitution line were significantly different from Chinese Spring; Fv/Fm and Fv/Fo of 3A, 7A substitution lines were significantly different from Chinese Spring from booting stage to filling stage under drought stress. [Conclusion] The genes regulating Fo and Fm may be located on 5B chromosome of Synthetic 6x in the control treatment. In drought treatment the genes regulating Fo and Fm may be located on 3A and 4D chromosome, respectively, and the genes regulating Fv/Fm and Fv/Fo may be located on 3A and 7A chromosomes, the problem is up for further study.关键词
