Abstract

The technique for recording of chlorophyll a fluorescence induction kinetics has been used for assessment of the physiological state of leaves of tillet (Tilia cordata), pendent white birch (Betula pendula), American arborvitae (Thuja occidentalis) in urban environments. Different sensitivity of plants to adverse growing conditions was observed. The most sensitive JIP test parameters such as PI(ABS), F(V)/F(0), F(V)/F(M), R(fd) are determined to be used as indicators of the physiological state of urban phytocenosis. Recommendations for the application of this technique in monitoring studies are given.

摘要

叶绿素a荧光诱导动力学记录技术已用于评估城市环境中椴树（心叶椴）、垂枝桦、美国扁柏叶片的生理状态。观察到植物对不利生长条件的不同敏感性。确定了最敏感的JIP测试参数，如PI(ABS)、F(V)/F(0)、F(V)/F(M)、R(fd)，用作城市植物群落生理状态的指标。给出了该技术在监测研究中的应用建议。
