摘要： 为进一步揭示宁夏枸杞新品种‘宁杞6号’和‘宁杞8号’花蕾发育的生理生化机制，研究了‘宁杞6号’和‘宁杞8号’不同发育时期花蕾中可溶性糖、游离脯氨酸、游离总氨基酸、可溶性蛋白含量的变化趋势。结果表明‘宁杞6号’花药发育中可溶性糖、游离脯氨酸、可溶性蛋白含量高于‘宁杞8号’，游离总氨基酸低于‘宁杞8号’，‘宁杞6号’和‘宁杞8号’花药发育过程中花蕾中的可溶性糖、游离总氨基酸、可溶性蛋白变化规律不同，游离脯氨酸变化规律相同，四分体发育时期后‘宁杞6号’花蕾的可溶性蛋白代谢比‘宁杞8号’活跃。可溶性蛋白代谢异常可能与‘宁杞8号’花少、代谢较为缓慢有关。

Abstract: In order to reveal the physiological and biochemical mechanism on buds of Ningxia wolfberry new species-‘Ningqi 6’and‘Ningqi 8’, the authors compared the main material variation characteristics of different developmental stage of buds, including soluble sugar, free praline, total free amino acids, soluble protein. The results showed that the contents of soluble sugar, free praline, soluble protein of‘Ningqi 6’were higher than that of‘Ningqi 8’, the contents of total free amino acids of‘Ningqi 6’were lower than that of‘Ningqi 8’. The changes of soluble sugar, total free amino acids, free proline of different developmental stage of buds were different between‘Ningqi 6’and‘Ningqi 8’; soluble protein changes of different developmental stage of buds were same between‘Ningqi 6’and‘Ningqi 8’. After tetrad stage, soluble protein metabolism in‘Ningqi 6’was more active. Soluble protein metabolic abnormalities may result in fewer flower and slow metabolism in‘Ningqi 8’.
