摘要/Abstract

摘要： 以布氏轮藻（Chara braunii Gmel.）为研究对象,在两种不同的基质土壤中,模拟3种光环境,研究光照和基质对轮藻形态、色素模式和有性繁殖的影响。结果表明,随着光照的减少,两种基质上生长的植株高度、叶绿素与类胡罗卜素（Chla/Caroten）比值均显著增加,植株灰分比率降低,最大干重均出现在25%光照条件下,最小干重在5%光照条件下。与底泥基质相比,黏土基质株高更低,植株灰分比率更高,Chla/Caroten比值降低。二元方差分析表明,光照和基质类型对株高、灰分比率、干重和色素模式均有显著交互作用。

关键词: 布氏轮藻（Chara braunii Gmel.）, 光照, 基质, 色素模式

Abstract: In order to investigate the interactive effects of light level and substrate type on charophyte plants, the 3×2 factorial design of light intensity and substrate type was implemented on Chara braunii Gmel. under culture conditions. Results revealed that the plant height and the ratio of chlorophyll to carotenoid （Chla/Caroten） of C. braunii on the two substrates increased significantly, while the plant ash ratio decreased with the decrease of light intensity. And the maximum dry weight appeared under 25% light treatment conditions, and the minimum dry weight was under 5% light intensity conditions. Compared to sludge substrate, planton the clay substrate had lower plant height, higher ash ratio and lower Chla/Caroten. Two-way ANOVA analysis showed that light intensity and substrate type had significant interactions on plant height, ash ratio, dry weight and pigment pattern.

Key words: Chara braunii Gmel., light intensity, sedimental type, pigment pattern
