| 摘要 | This paper delves into and assesses the differences in biological traits and fruit nutritional composition of 3 varieties of Prunus humilis introduced from 2 different regions. Results showed that (i) the contents of protein, total sugar, and calcium of No.5 variety were higher those of the other 2 varieties, which was recognized as the most suitable variety for fresh fruit; (ii) the comparison of leaf areas index and fruit shape index of 3 varieties shows that the fruit shape index and individual fruit weight of the introduced varieties were higher than those of the control, the diameter of individual fruit of the introduced varieties higher than that of the control indicated that they had a higher fruit hardness, more dry matter accumulation and better fruit quality, and that the introduction region was more suitable for scale-up of P. humilis; (iii) there was a positive correlation with the number of fruiting branches and there was a significant negative correlation with individual fruit weight, while the leaf area had a significant negative correlation with the number of fruiting branches. The introduced varieties can develop normally in the 2 testing areas, notably, No.5 variety performed better than No.4 and No.6. Improving management is the prerequisite for maintaining proper number of fruiting branches and high yield. |
