| 摘 要： | 以野生欧李为试材,逐级提取不同形态的钙,研究欧李生长发育阶段(萌动期-开花期-果实发育期)主要结果基生枝各组织器官(木质部、韧皮部、花和果实、新梢)中不同形态钙(水溶钙、果胶钙、磷酸钙、草酸钙、剩余钙)的分配率变化及其与总钙分配的相关关系。结果表明:不同组织器官中钙吸收和分配与钙形态转化和分配密切相关,随欧李生长期发育进程,木质部和韧皮部中不同形态钙分配呈明显下降趋势,新梢中不同形态钙分配呈明显增长趋势,花器官中水溶钙、果胶钙和磷酸钙形态在盛花期均有一分配高峰,果实中果胶钙和水溶钙形态分配分别在果实发育初期和后期有一分配高峰;花和果实总钙分配率变化与输导组织器官木质部和韧皮部中各种形态钙的分配呈显著或极显著正相关关系,新梢总钙分配率变化与输导组织器官木质部和韧皮部中各种形态钙的分配呈显著或极显著负相关关系。欧李生长期结果基生枝各组织器官中存在钙形态转化与再分配,水溶钙和果胶钙形态是欧李果实钙素吸收积累的主要钙形态。

| Abstract: | The distribution ratio variation of different forms of calcium in different organs(xylem, phloem, flower and fruit, shoot)of the fruiting basal branch and their relationship to total calcium were studied by sequential extraction procedure during growth and development stage (budding, flowering and fruiting period) in order to provide the basic knowledge of calcium adsorption mechanism of wild Cerasus humilis. The results showed that calcium adsorption and distribution in different tissues and organs weres c... |
