不同质量等级零余子作种对南城淮山产量和品质的影响
Effects of different mass bulbils on yield and quality of Nancheng Huaishan
摘要
Abstract
[Objective]The research aims to study the effects of bulbils with different quality grade as seed tuber on the yield and quality of local yam variety Nancheng Huaishan in Jiangxi Province,thus providing theoretical basis for purification and efficient cultivation.[Method]The tuber weight,tuber length,and yield per plant of Nancheng Huaishan tuber(CK)were investigated with bulbil of different quality grades(≤2 g,2-4 g,4-6 g,≥6 g).The contents of nutrients such as soluble protein,reducing sugar,cellulose,soluble sugar,and starch were determined and analyzed.Furthermore,the content of sodium,magnesium,potassium,calcium,iron,manganese,zinc,copper,boron,and other mineral elements was also investigated.[Result]The weight and length of tubers,as well as the yield per plant,were significantly increased as the seed mass increased.The rate of commercial tuber was the highest,reaching 90.00%,and the yield per unit area increasing by 48.72%when the bulbil weight was above 6 g.Meanwhile,the content of soluble protein,reducing sugar,cellulose,soluble sugar,starch,and other nutrients were accumulated in bulbils with different quality grades,as did the content of various mineral elements,and the highest mineral content was observed in the bulbil above 6 g.[Conclusion]The bulbils of Nancheng Huaishan as seed tuber,especially the bulbil above 6 g,could significantly improve the yield and quality compared with the traditional tuber retention,which had important roles in the purification and rejuvenation of yam.This study could provide a theoretical basis for provenance selection and standardized production of Nancheng Huaishan.关键词
