摘要: 以中国石蒜(Lycoris chinensis)与石蒜(Lycoris radiata)为材料,研究其生长发育期鳞茎可溶性糖、蛋白质含量及POD活性的变化。结果表明,在花芽分化前期,2种石蒜鳞茎可溶性糖、可溶性蛋白质含量均增加,并出现峰值,但从花芽分化后期直到花期结束,可溶性糖含量均持续下降;在花期,2种石蒜鳞茎可溶性蛋白质含量均处于高水平,花谢后明显下降;石蒜展叶期间鳞茎可溶性蛋白质含量明显增加,而中国石蒜花谢后可溶性蛋白质含量处于低水平。在花芽分化前期,2种石蒜鳞茎POD活性呈直线上升,但后期POD活性略有降低;花期后,2种石蒜鳞茎POD活性出现短暂的低谷,随后随着气温的降低而出现一致性上升。

Abstract: Variation of soluble sugar, protein and POD activity in bulbs of both Lycoris chinensis and Lycoris radiata during the growth and development were studied. The results showed both soluble sugar and protein of two Lycoris plants increased and appeared peak value during the prophase of flower bud differentiation, but the content of soluble sugar decreased with the coming of florescence. During the florescence, the soluble protein content of two Lycoris lied in high level, and decreased after florescence. During the leaves growth the soluble protein content of Lycoris radiata rose evidently, and that of Lycoris chinensis reversed. During the prophase of flower bud differentiation, the POD activity in bulbs of two Lycoris ascended, while the anaphase slightly descended. After florescence, the POD activity in bulbs of two Lycoris appeared brief low value and soon after moved up with the temperature reduction.
