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 Lyciurn barbarurn L. were studied during its maturation. The results were as follows： the growth curves of Lyciurn barbarum showed double sigrnoid 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-highlow 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.
