研究种子萌发过程中生理生化的变化,胚和胚乳物质与能量代谢是种子生理学研究的重要内容之一。 人们对杉木地理种源及杉木种子作了许多研究,但有关杉木地理种源种子胚、胚乳在萌发过程中的同工酶研究尚未见报导。本文试图对杉木不同种源种子过氧化物酶同工酶、酯酶同工酶、α—淀粉酶同工酶进行研究,为杉木种子及种源研究提供基础材料。 Research on the physiological and biochemical changes of seed germination process, embryo and endosperm material and energy metabolism is one of the important contents of seed physiology. Many studies have been done on the geographical provenance of Chinese fir and the seed of Chinese fir, but no studies have been done on the isozyme study of seed embryo and endosperm during germination. In this paper, we try to study the peroxidase isoenzyme, esterase isozyme and alpha-amylase isoenzyme in different provenance seed of Chinese fir, and provide the basic materials for the study of Chinese fir seed and provenance.
