摘  要:
以紫鸭跖草为试材,研究了室内常见有毒气体二甲苯对观叶植物的毒性影响及生理指标的变化。结果表明:二甲苯处理浓度与叶片损伤程度成正相关;叶绿素含量下降的程度与二甲苯的胁迫浓度成正比,叶绿素a/b比值呈现先降低后回升的趋势;相对膜透性与二甲苯浓度呈正相关;脯氨酸的含量呈明显升高的趋势;丙二醛含量呈现先逐渐升高后降低的现象。

摘  要:
This article aims at discussing the toxicological effects on indoor foliage plant Setcreasea purpurea by gaseous dimethylbenzene(Abbr.DMB) and the change of physiological guideline.It showed that leaf damage degree submits direct ratio with DMB concentration in the appearance,also was degressive extent of chlorophyll content.Chl.a/b ratio presents depressed trend in forepart and then elevatory.Relative membrane permeability and proline content took on elevatory with DMB concentration.MDA content hoists gradually and then depressed later.
