| 中文摘要: |
| 通过对枸杞果实发育过程中果实生长模式、碳水化合物、有机酸、Vc、可溶性蛋白质、多糖、类胡萝卜素含量的测定,系统分析它们在果实整个生长发育过程中的动态变化。结果表明枸杞果实发育呈双“S”曲线;可溶性总糖、还原糖含量生长前期变化不明显,近成熟时迅速积累至最高;淀粉含量前期积累,后期降低,成熟时果实中不含淀粉;总酸含量呈现先升高后降低的变化趋势;Vc含量变化总体上呈先升高后降低的变化趋势;果实在发育前期可溶性蛋白质含量较低,随后升高,至花后27d达最高峰,以后逐渐减少;多糖、类胡萝卜素含量在发育前期较低,于花后27 d迅速增加,到成熟时达最大值。 |

| The changes of growth phase,carbohydrate,organic acid,vitamin C,soluble protein,polysaccharomyces and carotenoid in Lycium barbarum L.were studied during its maturation.The results were as follows: the growth curves of Lycium barbarum showed double sigmoid pattern;The content of soluble sugar and reducible sugar changed unremarkably in the early stage of berry development,sugar accumulated rapidly at the early ripening time; The content of starch accumulated in the early stage,and decreased to zero at maturation;The content of titratable acid were low in the early stage of berry development,then increased with the development of berry during maturation,and then decreased lightly;The curve of vitamin C content showed low-high-low tendency during berry development;At first stage the content of soluble protein in berry increased rapidly,and reached the maximum at the 31st day after blossom,after that declined gradually;The content of polysaccharomyces and carotenoids was lower in early stage of berry development,from the 27th day after blossom increased rapidly,and reached the maximun at maturation |
