龙船花花蕾发育过程中部分生理指标的变化

以龙船花为材料,测定龙船花在花蕾发育的不同时期叶片叶绿素、丙二醛、可溶性蛋白质和可溶性糖等生理指标的含量,并分析它们随着花蕾发育的变化规律。结果表明:随着花蕾的发育,龙船花叶片中可溶性糖、可溶性蛋白含量大致呈下降趋势;丙二醛含量大致呈增加趋势;叶绿素含量呈先上升,随着可溶性糖达到最大值后呈现下降趋势。通过研究其花蕾发育过程中生理生化变化,揭示其衰老的内在规律,拟为龙船花的开花生理及花期调研究控提供理论依据。

Study on the Physiological Characteristics of Ixora chinensis during the Flower Buds Development

Took the Ixora chinensis as the material, determined the content of chlorophyll, MDA, soluble protein and soluble sugar content and other physiological indicators in leaves at different stages of bud development, and analyzed their variation with the development of bud. The results showed that： with the flower bud growth, the content of soluble sugar and soluble protein in Ixora chinensis leaves declined; while MDA in leaves rised; the amounts of chlorophyll increased first and then decreased with a maximum value of soluble sugar. Through the study of physiological and biochemical changes during bud development, to reveal the internal rule of flower senescence in Ixora chinensis, and provide the theoretical basis for the physiology of flowering and the florescence control of Ixora chinensis.
