以砀山酥梨为试材,于花后15d对果实套袋,观察不同发育时期果实石细胞团分布,测定石细胞、木质素及木质素中间代谢产物含量、代谢相关酶活性,探讨套袋对砀山酥梨石细胞发育及木质素代谢的影响。结果表明,套袋后砀山酥梨果实石细胞团含量下降31.6%,数量减少28%,直径减小45.8%。木质素含量下降13.9%,木质素含量与石细胞含量呈极显著正相关。梨 Dangshansu pear was used as test material to bag the fruit 15 days after anthesis, the distribution of stone cell mass in different developmental stages was observed, and the contents of intermediate metabolites, metabolites and enzymes in stone cells, lignin and lignin were determined. Effect of Stone Cell Development and Lignin Metabolism in Dangshan Pear. The results showed that the content of stone clump of Dangshan Suli pear after bagging decreased by 31.6%, the number decreased by 28% and the diameter by 45.8%. Lignin content decreased by 13.9%, lignin content and stone cell content was extremely significant positive correlation. pear
