摘要：以普通油茶（Camellia oleifera）长林系列18#品种芽苗作为砧木，取普通油茶长林系列4#、18#品种为接穗，采用芽苗砧法嫁接，通过对嫁接体结合部发育过程中的死亡率及理化指标的测定，研究了嫁接体的亲和性生理。结果表明：0—24h与1—55d所得结论相同，即在2个嫁接组合中所测的各生理指标（除可溶性糖质量分数）变化趋势基本一致，嫁接体结合部SOD活性越低。POD活性越高。MDA质量摩尔浓度越低．可溶性蛋白质量分数越高，嫁接组合亲和性越好；嫁接体结合部SOD活性、POD活性、MDA质量摩尔浓度峰值出现的时间较早．嫁接组合亲和性较好：嫁接组合亲和性与结合部CAT活性未见相关性。
For the mechanism of physiological affinity, we studied the death and the physiological and biochemical indexes of two different nurse seed grafted union of ChangLing 4#/ChangLing 4# and ChangLing 18#/ChangLing 18#. The results of 0-24 h and 1-55 d were the same. The change trend of physiological indexes of two graft combinations were basically the same except soluble sugar content. The SOD activity and MDA content in the combination with a good affinity were lower than those in the combination with a poor affinity. The POD activity and soluble protein in the combination with a good affinity was higher than those in the combination with a poor affinity. The peak of SOD activity, POD activity and MDA content appeared earlier in the combination with a good affinity than those in the combination with a poor affinity.
