‘KRS’芒果发育过程中糖积累与代谢相关酶活性的关系
The Relationship between Sugar Accumulation and Related Enzyme Activities during the Development Process of ‘KRS ’ Mango Fruits
摘要
Abstract
Objective] The aim was to discuss physiological mechanism of sugar accumulation and transformation in mango fruit.[Method] The relationship between the contents of starch, sucrose, glucose and fructose, and the activities of amylase, sucrose metabolizing enzymes in-cluding acid invertase (AI), neutral invertase (NI), sucrose synthase(SS) and sucrose phosphate synthase(SPS) during fruit development process in KRS mango were studied.[Result] The results showed that starch, fructose and glucose accumulated at the early stage of fruit de-velopment, amylase activity dropped to minimum along with the starch decomposition and sucrose accumulated at the ripening stage .The ac-tivities of AI maintained higher throughout the developmental stage, dropped slightly at the ripening stage.The SPS activities dropped slightly in middle stage of fruit development, then raised to the highest at the ripening stage.The activities of SS and NI maintained minimum and changed very little throughout the development process.The starch content had positive correlation with amylase.The contents of sucrose and glucose had significantly positive correlation with the activities of SPS and SS .The content of fructose had significantly positive correlation with SS and AI.[Conclusion] Decomposition in starch, reduction in AI, increment in SS and SPS activities are responsible for sucrose accumula-tion in developing fruits of mango ‘KRS’ .关键词
