The present study was aimed at screening tolerant tree species for environmental stress in degraded land in tropics and clarifying the tolerant mechanism.(1) Growth response of some tropical leguminous trees was studied by solution culture controlled in various pH.The adaptable range for pH was varied among the species.(2) As an aluminium-tolerance mechanism, excretion of organic acids in tropical leguminous trees was studied. Excretion of citrate was induced by aluminium stress from the roots of Praserianthes falcataria.(3) Stress response in seed germination of swamp trees was studied. Melaleuca cajuputi was adapted to stress condition of degraded swamp.(4) As a flooding-tolerance mechanism, activity of fermentative enzyme in Melaleuca cajuputi was studied. ADH activity in the roots was induced by flooding stress.(5) The tissue culture system of dipterocarp trees was established.

本研究旨在筛选热带退化土地环境胁迫耐受树种，并阐明其耐受机制。(1)采用溶液培养法研究了几种热带豆科树种在不同pH条件下的生长反应，结果表明，不同树种对pH的适应范围不同。(2)作为一种耐铝机制，有机酸的分泌在热带豆科树木进行了研究。铝胁迫诱导黄花Praserianthes falcataria根系分泌柠檬酸盐。(3)研究了沼泽树种种子萌发的胁迫反应。白千层适应退化沼泽的胁迫条件。(4)作为白千层耐腐机制的一个方面，对白千层发酵酶的活性进行了研究。淹水胁迫诱导了根中ADH活性的升高。(5)建立了龙脑香树的组织培养体系。
