The changes of morphological and physiological characteristics of Tilia miqueliana and Tilia cordata were studied to reveal the physiological mechanisms of resistance to flooding stress.The results were shown as follows:
1. Effects of flooding stress on the external morphology of Tilia miqueliana and Tilia cordata were shown as:Wilting leaves prolapse, fall off death under flooding stress, formation of hypertrophied lenticels and adventitious roots (AR) on the submerged stem, plants eventually withered....
