摘　　要：目的:探索麻疯树早期对铝胁迫的生理反应,进一步研究植物耐铝的生理生化机制。方法:以麻疯树种子为材料,应用砂培法,设计pH为5.6的AlCl36个处理浓度(0、25、50、100、200、400μmol/L)和3个时间梯度(7、14、21d),研究铝胁迫对麻疯树幼苗生长的影响。结果:随着铝浓度及胁迫时间的增加,麻疯树幼苗的根长、茎长、植株鲜质量、叶绿素含量的总体水平降低。结论:麻疯树幼苗叶片在铝毒逆境胁迫环境中具有一定的自我保护和修复能力。Objective:The purpose of this study was to explore the physiological response of Jatropha curcas to alumi⁃num stress in the early stage,in order to further study the physiological and biochemical mechanism of plant alumi⁃num tolerance.Method:The paper takes the seeds of Jatropha curcas as material,design 6 treat concentration(0、25、50、100、200、400μmol/L)and 3 time gradients(7、14 and 21d)of AlCl3 which pH is 5.6,to study the adjusting ef⁃fect of anti metal stress mechanism of Al3+to the Jatropha curcas under the condition of AlCl3 adversity stress.Result:As the stress density of aluminum liquid and time of stress increasing,the root length,stem length,fresh mass and chlorophyll content of the Jatropha curcas plant drop over all.Conclusion:All these critical factors indicate that the seedling leaf of Jatropha curcas has certain self protection and restoration ability under the condition of aluminum toxicity adversity stress.
