| 摘 要： | 采用盆栽法，研究了不同盐碱胁迫对吉89 45和吉农大10的叶绿素总量、叶绿素a和叶绿素b含量的影响。结果表明，同一盐碱胁迫处理下，生育前期叶绿素含量低，之后逐渐增加，到抽穗期达最大值，然后又开始下降，2个品种叶绿素含量变化趋势基本一致。各处理的叶绿素含量始终低于对照。另外，不同处理中叶绿素a含量的变化范围始终大于叶绿素b含量的变化范围。

| Abstract: | Effect of different saline-alkali stress on chlorophyll, chlorophyll a and chlorophyll b contents of two rice cultivars (Ji 89-45 and Jinongda 10) were studied with pot experiments. The chlorphyll contents were low at the early growth stage,then increased gradually and reached the highest value at the flowering and milk stage, and no difference in change tendency of chlorphyll content between the two cultivars was found. Chlorphyll contents under the stress treatment were lower than those under control treatment. In addition, the variable range of chlorphyll a content was always wider than that of chlorophyll b content. |
