对花生栽培种(A.hypogaea L.)四大类型的16个品种萌发后不同日数的子叶酯酶同功酶进行了研究。结果表明,在发芽过程中,除多粒型的文登小粒红外,其余15个品种间子叶酯酶同功酶的主酶带无差异;次酶带在类型间、品种间均有差异;类型间、品种间子叶酯酶同功酶有着明显不同的消长规律。酶带出现的高峰期是发芽的第9天,最多同时出现19条酶带,最少时15条,发芽全过程共出现23条酶带。花生的早熟性似与某些酶带出现和消失的早晚有关。 The cotyledon esterase isoenzymes of 16 cultivars of A. hypogaea L. from different days after germination were studied. The results showed that in the process of germination, except for the multi-grain type Wendeng granule infrared, the main enzyme bands of cotyledon esterase isoenzyme in the remaining 15 cultivars had no difference; the second enzyme bands differed in types and varieties; , Varieties of cotyledon esterase isozymes have significantly different growth and decline. The peak appeared in the first 9 days of germination, up to 19 simultaneous bands, at least 15, the emergence of a total of 23 strips during the germination. The precocity of peanuts appears to be related to the appearance and disappearance of certain bands.
