摘　　要：【目的】分析与白木纳格葡萄败育相关的生理生化指标。【方法】以红木纳格葡萄种子、白木纳格葡萄正常发育种子和败育种子作为研究对象,研究2种葡萄的果实及种子生长发育过程中的大小外观指标、可溶性糖含量、可溶性蛋白含量、MDA含量、POD活性、SOD活性及CAT活性6种生理指标,研究白木纳格葡萄种子败育的时期及相关影响因子。【结果】白木纳格葡萄的种子败育表现在43d前已经出现,可溶性蛋白含量与种子败育呈显著负相关,可溶性糖含量、MDA含量、POD活性、SOD活性及CAT活性与种子败育相关性未达到显著水平。【结论】白木纳格葡萄种子的败育时期在盛花后37~43 d,可溶性蛋白含量是影响木纳格葡萄种子发育的主要理化指标。【Objective】To determine the physiological and biochemical indexes related to the abortion of white Munake grape.【Methods】In this experiment,the characteristics of the size and appearance,soluble sugar content and soluble protein of the growth and development of the fruits and seeds of the two grapes were mainly based on the seeds of the mahogany,and the normal development seeds and the abortive seeds of the white Munake grapes were used as research objects.The six physiological indexes of content,MDA content,POD activity,SOD activity and CAT activity were studied,and the period of seed abortion and related factors of white Munake grape were comprehensively analyzed.【Results】The seed abortion of white Munake grape began to appear before 43 days,and the soluble protein content was significantly negatively correlated with seed abortion.Soluble sugar content,MDA content,POD activity,SOD activity and CAT activity and seed abortion.The correlation did not reach a significant level.【Conclusion】The abortive period of white Munake grape was from 37 days to 43 days after flowering and soluble protein content is the main physical and chemical index that affects the development of Munake grape seed.
