摘要
通过测定麻疯树新鲜成熟种子中不同组织中总钙和不同形态类型钙物质含量,探索麻疯树种子发育过程中对钙的分布规律和储存形式。结果表明,麻疯树新鲜成熟种子胚中钙形态主要以NaCl钙和HAC钙形式为主,钙形态在种子胚的发育过程中主要起到源和库的作用,外种皮中总钙含量丰富,主要以HCl钙形态存在,对参与种子的结构和胚的发育起到积极作用。另外,麻疯树种子胚中可溶性蛋白质和可溶性糖含量与胚中高钙含量和高钙形态含量密切相关,而大分子物质的积累对促进麻疯树适应高钙质环境特征的生长发育过程具有重要意义。
The total calcium content and the content of different morphology form calcium in different tissues of fresh ripe seeds of Jatropha curcas were determined,and the store mechanism and the distribute regularity of calcium in Jatropha curcas seeds during growth were explored.The results showed that the mainly variation of calcium in the embryo of fresh ripe seeds were NaCl-calcium and HCl-calcium,the two type of calcium played important roles of fountain and warehouse during the growth of embryo.The mainly calcium variation in mesocarp was organic soluble calcium,which had positive function in building the structure of seeds and in the growth of embryo.Additionally,the content of soluble protein and soluble sugar in the seeds of Jatropha curcas had closely relation to the higher calcium content and higher calcium variation content,and the accumulation of macromolecules had positive significance for the Jatropha curcas to adapt the higher calcium environment.
