根据对水稻滇榆1号及其亲本品种各生育期的酯酶同工酶谱进行20次测定的资料,找出了杂种和亲本品种的酯酶同工酶谱特征;发现各品种在休眠期和不同生育期中有不同的酶带活跃,不同品种生育期中酶活性变化特点不同,大致可分为平稳型和波动型两类。初步证明,酶活性变化类型不同的品种杂交,从后代中选择酶谱互补的中间类型是育成优良品种的一个重要条件。
Based on the data of 20 isozymes of esterase isozymes of different stages of rice Dian-yu-1 and its parents, the characteristics of esterase isozymes of hybrid and parental varieties were found. During the dormant period And different growth stages have different enzyme bands active, different varieties of different growth stages of the characteristics of changes in enzyme activity can be divided into two types of stable and fluctuating. It was initially proved that it is an important condition to cultivate the fine varieties that the intermediate types of the complementary zymograms are selected from the progenies by crossing different varieties of different types of enzyme activities.
