测定了越冬期间不同抗寒性无花果品种枝皮同工酶的变化.结果表明,酯酶同工酶带数量的变化与季节温度变化存在一致性,而过氧化物酶则不然.抗寒性越强的品种,酯酶同工酶带越少,而过氧化物酶同工酶则不明显.越冬过程中,过氧化物酶和酯酶同工酶都有新酶带的出现、原有酶带的消失以及活性的变化,并与品种抗寒性强弱有一定关系. The changes of the bark isoenzyme of figs with different cold-resistance during winter were measured.The results showed that there was consistency between the change of the number of isozyme bands and the seasonal temperature, while the peroxidase was not. Strong varieties, esterase isozyme band with less, and peroxidase isoenzyme is not obvious overwintering process, peroxidase and esterase isozymes have a new enzyme band, the original enzyme The disappearance of the band as well as the change of the activity, and has the certain relation with the cold hardiness of the variety.
