研究胡椒花穗发育过程中不同功能叶营养物质动态变化.结果表明,在胡椒花穗发育过程中,不同功能叶供磷、镁和可溶性糖差异显著,供磷和可溶性糖主要为距花穗最近的完全稳定叶,供镁主要为距花穗最近和次最近的完全稳定叶;距花穗最近的完全稳定叶是花穗发育的主要营养供应叶;磷、镁和可溶性糖可作为研究功能叶与花穗发育关系的重要指标.%The dynamic changes of the nutrient in different functional leaves at spica developmental stages of pepper was studied. The results showed that in the development process of pepper flower cluster, there were significant differences between different functional leaves on the supply capacity of the phosphorus (P), magnesium (Mg) and soluble sugar (SS). P and SS were mainly supplied by the completely stable leaf (CSL) nearest to the flower cluster. Mg was mainly from the CSL nearest and next-nearest to the flower cluster. The CSL nearest to the flower clusters were the main supply leaves to the flower clusters' development. P, Mg, and SS could be the important indexes on the relationship of functional leaves and flower clusters' development.
