以橡胶树９３－１１４、ＲＲＩＭ６００品系幼苗的叶片为材料，以过氧化物酶和细胞色素氧化酶同工酶的酶谱带数量与活性的动态变化为依据，系统研究它们对低温、变温以及多效哇（ＰＰ＿（３３３））的效应，结果表明，室温下２个品系之间同工酶谱带数量均不同；ＲＲＩＭ６００品系比９３－11４品系敏感；过氧化物酶同工酶比细胞色素氧化酶同工酶敏感。比较不同条件下诱导呈现的新的同工酶带，发现ＰＰ＿（３３３）在常温下诱导呈现的新的同工酶谱带，与低温、变温条件下所呈现的新的同工酶谱带的位置（Ｒｆ值）完全相同。
Based on the dynamic changes of enzyme bands and activities of peroxidase and cytochrome oxidase isozymes, the leaves of rubber tree 93-114 and RRIM600 strains were used as materials to systematically study their effects on low temperature, variable temperature and multi-effect The results showed that the number of isoenzyme bands was different between the two strains at room temperature. The RRIM600 strain was more sensitive than the strain 93-114. The activity of peroxidase isoenzyme was higher than that of cytochrome oxidase Isozyme sensitive. Compared with the isozyme bands induced by different conditions, it was found that PP_ (333) induced a new isozyme band at room temperature, which was similar to that of the new isozyme band presented by low temperature and variable temperature Position (Rf value) exactly the same.
