摘　　要：对李属８个种２３０余份资源的单果重、可溶性固形物含量、总糖含量、果实发育期及７８份资源的自然结实率等数量性状的调查数据进行了统计分析，提出了新的分级评价标准，避免了以往资料中相应项目分级评价标准过低或过高等不合理现象，使分级评价标准与国际标准接轨并更接近李资源的实际情况。Average fruit weight,soluble solid content,total sugar content,total acid content,and fruit development period of 233 plum resources from 8 species and the open pollinated fruit set percentages of 78 resources were investigated.The statistical data and new evaluating criteria for studied characters were given,in which the improper either too high or too low criteria in Descriptor of Fruit Germplasm Resources were amended.The new evaluating criteria should be more consistent with international criteria and the actual situation of plum resources.
