摘要
Abstract
The foliar stomatal traits of Ligustrumlucidum from 13 sampling sites with different environmental conditions in Xi'an were studied.The results showed that the stomatal traits,as stomatal density,stomatal width,stomatal length and stomatal pore surface area were significant differences among the investigated sites.Stomatal density increased with the increase of environmental stress levels,and presented positive correlation (r =0.680,p =0.011).However,the stomatal width,stomatal length and stomatal pore surface area were on the contrary.They all showed significantly negative correlation with environmental stress levels (r =0.784,0.787,0.722;p =0.002,0.001,0.005).All the results showed that the stomatal traits including stomatal density,stomatal width,stomatal length and stomatal pore surface area could be used as bioindicators for environmental stress.关键词
