作者根据叶片的淀粉凝胶电泳结果,分析了柑桔属间、种间的同工酶及其相应的基因。已肯定了三种酶的基因位点和等位基因数量及其基因型组成。这三种同工酶是苹果酸脱氢酶、己糖激酶和异柠橼酸脱氢酶。这些酶受四个基因(位点)共19介共显性等位基因控制,其中11个只存在于酸柠檬、酸橙、柚子、柠檬、佛手、葡萄柚、宽皮枯、甜橙中。柚子中的己糖激酶和异柠檬酸脱氢酶同工酶变异最大。 Based on the results of starch gel electrophoresis, the isozymes and their isozymes of citrus were analyzed. The three enzyme loci and alleles have been identified and their genotypes have been identified. The three isozymes are malate dehydrogenase, hexokinase and isocitrate dehydrogenase. These enzymes are controlled by a total of 19 genetically dominant alleles of four genes (loci), of which 11 are found only in sour lemons, limes, grapefruits, lemons, bergamot, grapefruit, kibble, and orange. Grapefruit hexokinase and isocitrate dehydrogenase isoenzyme variation.
