摘要
采用人工熏气法,对37种园林绿化植物对氯气(Cl2)的抗性及吸收能力进行了研究,通过系统聚类分析方法,将参试植物的抗性及吸收能力分别从弱到强划分为5个等级(Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ)。实验结果显示:37种植物对氯气抗性存在较大差异,抗性最强的为茶花Camellia japonica,最弱的为乳源木莲Manglietia yuyuanensis,红花木莲Manglietia insignis和交让木Daphniphyllum macropodum;37种植物对氯气吸收能力差异显著,吸收能力最弱的为乳源木莲,熏气前后氯元素质量分数差为0.50mg·kg-1,最强的为火棘Pyracantha fortuneana,熏气前后氯元素质量分数差变化8107.68mg·kg-1。
With artificial fumigation, resistances and absorbencies to gaseous chlorine （Cl2） of 37 common plant species were graded into five levels： I , II , HI, IV, and V（from weak to strong）, using a cluster analysis with DPS software. Results showed that the strongest resistance was with Camelliajaponica and the weakest with Manglietia yuyuanensis, Manglietia insignis, and Daphniphyllum macropodum. The greatest absorbency was with Pyracanthafortuneana （8 107.68 mg·kg^-1） and the weakest with Manglietiafordiana （0.50 mg·kg^-1）. [Ch, 2 fig. 5 tab. 11 ref.]
