据研究,同功酶的酶谱作为一项生理、生化指标有三种用途;( 1)鉴别种质特征;(2)病理鉴定;(3)区别植株和器管的生理状态。本研究主要测定了苹果、梨几个主要品种幼果和贮藏期果实过氧化物酶同功酶酶谱的变化,并测定了长把梨红心病果实的过氧化物酶酶谱。 材料与方法 以苹果、梨几 According to the research, zymogram of isoenzyme has three purposes as a physiological and biochemical index; (1) Identification of germplasm characteristics; (2) Pathological identification; (3) Physiological state of plants and vessels. In this study, the changes of peroxidase isoenzymes in young fruits and fruits of apple and pear were measured, and the peroxidase zymogram of longan pear heart disease was measured. Materials and methods to apple, pear a few
