摘　　要：根据欧李杂种实生苗营养性状进行苗期预选研究。结果表明:栽培性状优良的个体往往在其苗期即表现出优良的营养性状,如叶片宽大、厚,色浓绿,芽大饱满等,在欧李实生选种过程中,可以通过预选筛选出苗期营养性状优良的个体,以降低选种成本。但并非苗期营养性状不良的个体栽培性状均不符合选种目标。在实生选种工作中,还需做到重点选育与全面培养的兼顾。According to the nutritional traits of Prunus humilis hybrid seedlings, did the research of seedling pre-selection. The results showed that the individuals with excellent cultivation characters often showed excellent nutritional traits in seedling stage, such as leaves were large and thick, the color of leaves was dark green, sprouts were big and plump, etc. In the cross of seed selection, could select the individuals with excellent nutritional traits in seedling stage to reduce the cost of seed selection by pre-selection. But not all the cultivate characters of individuals with bad nutrition characters did not meet the target of seed selection. So in the work of seed selection, need to do both key selection and comprehensive training.
