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 nutrients in different functional leaves during the development of pepper spikes were studied. The results showed that there were significant differences in P, Mg and soluble sugar among different functional leaves during the spike development of pepper. Phosphorus and soluble sugar were the most complete and stable leaves from the spikes, and were mainly from the nearest spikes and times The most complete stable leaf lately; the completely stable leaves nearest to the spikes are the main nutrient supply leaves for spike development; phosphorus, magnesium and soluble sugars can be used as important indicators to study the relationship between functional leaves and spike development.
