摘　　要：通过对3种砧木嫁接的大石早生李的枝皮、芽、春梢营养枝叶片POD(过氧化物酶)活性、POD同工酶酶谱特性进行测定,并对其生长势指标进行观测、分析。结果表明,不同砧木对李树生长势影响显著,在树高、干高、冠径、树冠体积4项生长指标上均以毛樱桃为砧木的大石早生李生长量最小,以毛桃、山杏为砧木的大石早生李生长量较大。不同砧木嫁接的大石早生李POD活性差异显著,以毛樱桃为砧木的大石早生李POD活性高,以毛桃、山杏为砧木的大石早生李POD活性较小。POD活性与树高、干周、冠径、树冠体积呈显著负相关,与砧木的矮化性呈负相关。POD同工酶酶谱带数与树高、冠径、树冠体积呈显著负相关,但与干周无显著相关性。Prunus salicina  has been grafted on three kinds of stocks. By measuring the POD activity and the zymogram of POD isoenzyme of branch barks,buds,and leaves of spring branches,through observing and analyzing the growing norms,we find that different stocks have striking influence on the growing of the plum. The height of the tree and trunk, the crown diameter and the volume of crown are all the smallest on Cerasus tomentosa stock. The 4 growing norms on stocks of Amygdalus davidiana and Armeniaca sibirica are higher than those on Cerasus tomentosa. Different stocks have different effects on the activity of POD. POD activity on Cerasus tomentosa stock is higher than that on Amygdalus davidiana and Armeniaca sibirica. The POD activity have a strikingly negative relationship with the height of tree,trunk girth,diameter of crown,the volume of the tree crown,and the dwarfed nature of the stocks. The number of belt of POD biochem isoenzyme have a strikingly negative relationship with the height of tree,the diameter of crown,and the volume of the crown. However,the number of belts of POD biochem isoenzyme have no striking relationship with the trunk girth.
