摘要
笔者结合国内外对于棉纤维发育过程中纤维细胞内部生理生化反应的最新研究成果,依据棉花纤维比强度形成机制,综述了棉纤维比强度形成的关键时期次生壁加厚期,纤维素生物合成的物质变化、参与调控其合成的酶系(纤维素合成酶,蔗糖合成酶,β-1,3-葡聚糖合酶,β-1,3-葡聚糖酶,吲哚乙酸氧化酶和过氧化物酶)及影响合成的主要因素(基因型,温度,激素)等方面的研究进展。为探索改善棉纤维比强度的生理调控途径和培育高纤维强度的棉花品种提供了理论依据。
Based on the current research results of physiological and biochemical reactions in cotton fiber cell during fiber development and the formation mechanism of cotton fiber strength, this paper reviewed the current status on substance change, related and regulated enzymes (cellulose synthases, sucrose synthase, β-1,3-Glucan synthase, β-1,3-Glucanase, IAA oxidase and peroxidase) and influencing factors (genotype, temperature and hormone) for cellulose synthesis during secondary wall thickening which is the key period to cotton fiber strength formation. This paper may serve as the basis for improving the ways of physiological adjusting of fiber quality and cultivating new excellent breeds of high fiber strength.
