摘　　要：黄山松不同龄阶针叶衰老指标的比较研究＊李东林严景华曹恒生蔡丽琼叶要清关键词黄山松针叶衰老自由基衰老是最终导致有机体或器官死亡的变化过程，是生命过程的必然规律。对植物体衰老的研究起步较晚，且主要是在一些农作物上进行，如水稻［１］、大麦［２］、小麦［３］...This paper was about the study on senescence of Pinus taiwanensis .The results showed:with the increase of age, (1)the contents of chlorophyll and protein,the radio of chlorophyll a/chlorophyll b declined;(2)the activity of SOD and CAT decreased and decrease of the activity of CAT was more significant;(3)the content of MDA rose.It is concluded that the content of chlorophyll and protein,the radio of chl.a/chl.b could be regarded as the index of senescence of P. Taiwanensis. There was a direct interrelation between leaf senescence and free radical.
