摘要
通过对黄瓜果长、果周长和果实体积非离体间接测定 ,模拟计算黄瓜果实鲜重、干重及碳、氮含量的最佳回归方程 .结果表明 :果实鲜重与果实干重以果实体积的线性回归方程计算为最佳 ;果实可溶性总糖以果实周长和果实体积的二元多项式回归计算为最佳 ;
Fresh fruit weight, dry fruit weight, gross soluble sugar and nitrogen content can be measured indirectly and nondestructively by fruit length, fruit circumference and fruit volume. The best relationship between fresh and dry fruit weight and fruit volume, gross soluble sugar content and fruit circumference and volume, nitrogen content and fruit length, were linear regression, dual polynomial regression and polynomial regression, respectively.
