伏地尖辣椒的种性研究

STUDIES ON THE GERMPLASM OF FUDIJIAN PEPPER(Capsiucm annuum L.)

对长沙、湘潭、株洲、衡阳4个产区的伏地尖辣椒进行了植物学、生物化学等多方面的综合研究.结果表明:单果重和单株结果数量是制约单株产量的主要性状,单株结果数和侧枝数通过制约其它性状对产量产生负作用.辣椒果实发育过程中,维生素C、可溶性糖、蛋白质均随果实生理成熟而增加,至红果时含量最高.单果重与果实维生素C 含量呈极显著负相关.4个产区伏地尖辣椒在果型、株型、早熟性等多个性状上都发生了较大的变异,初步可分为2个类型.

The pepper collected from 4 areas of Changsha,Xiangtang,Zhuzou andHengyang was studied in botanical,biochemical and other aspects.The results show that sin-gle fruit weight and fruit number per plant are the major components affecting the yield,whereas number of fruit and branches per plant have a negative influence on the yieldthrough restricting other yield components.Vitamine C,soluble sugar,and protein content infruit increase with fruit maturation and come to maxium volume at red fruit stage.Singlefruit weight is negatively correlated to Vitamine C content.In addition,there is significantvariation in maturity,fruit shape,and plant from among the materials collected from the 4areas and they can be divided into 2 types.
