本研究以香梨、鸭梨、新梨6号、75-4-1等18个梨品种(品系)为研究材料,分别测定果实单果重、果柄长、果形指数、果心大小、种子数、维管束数、可溶性固形物含量共7个性状。试验结果表明:砀山梨果柄长度性状稳定性好,新梨6号相较于其它品种(品系)果心小,香梨、鸭梨、砀山梨维管束少,果肉细腻,84-4-72、大果水晶可溶性固形物含量高。香梨与新梨6号单果重存在显著性差异,砀山梨与新梨6号果柄长存在显著性差异,香梨与鸭梨、新梨6号果形指数存在显著性差异,香梨与新梨6号果心大小存在显著性差异,香梨与新梨6号维管束数存在显著性差异,香梨与鸭梨可溶性固形物含量存在显著性差异,香梨、鸭梨与新梨6号种子数不存在显著性差异。果柄长与果形指数、果心大小与果柄长、果心大小与果形指数、维管束数与单果重、可溶性固形物含量与单果重呈显著性相关。
In this study, pear varieties (pear, pear, pear No. 6, 75-4-1) were used as materials in this study. Fruit weight, fruit stalk length, fruit shape index, fruit heart size, Number of vascular bundles, soluble solids content of a total of seven traits. The results showed that the length and length of the fruit of the pear were stable, the pear number of Xinli 6 was lower than that of other varieties, the number of vascular bundles of fragrant pear, pear and pear was less, the pulp was delicate, 84-4-72 , Large fruit crystal soluble solids content. Pear and Xin pear 6 single fruit weight there is a significant difference between the pear and pear new pear Pears 6 stalk length significant difference, Fragrant pear and pear, Xin pear 6 fruit shape index significant differences pear and There was a significant difference in the heart size of Xinli 6, there was significant difference in the number of vascular bundles between Xiang pear and Xinli 6, and the content of soluble solids in pear and pear were significantly different. No significant difference in the number of seeds. Fruit length and fruit shape index, heart size and stem length, fruit size and fruit shape index, vascular bundle number and fruit weight, soluble solids content and fruit weight was significantly related.
