Analysis of walnut fruit quality based on source-sink relationships

In the paper, we investigate relationship between walnut fruit quality and leaf-to-fruit ratio (LFR). The LFR had a significant effect on physical of walnuts (P < 0.05), volume, fresh weight, dry nut weight kernel increased with an increasing LFR. However, no crude protein fat contents > 0.05). number cells per unit area cross-sectional green husk 5L : 1F were significantly higher than those 1L 3F 2L was that other LFRs There difference in NDW natural girdled fruit-bearing shoots We concluded high carbohydrate availability augmented size by kernels. change kernels, possibly due to proportion sugar distribution not affected Two leaves good light necessary ensure normal growth development one shoots.
