套袋对黄冠梨果实中多糖和脂类分布的影响
Effect of bagging on distribution of polysaccharide and lipid in Huang-guan pear fruit
摘要
Abstract
Distribution of polysaecharide and lipid in fruit bagged with white one-layer and three-layer bag was observed, and its relationship with browning spot of Huangguan pear was explored as well. The results showed that： polysaceharide in fruit mainly distributed in epidermal cells, tannin layer and stone cells, and showed a little in parenchyma cell wall. The staining of polysaecharide in fruit gradually increased with fruit development, showed the heaviest at 70 days after full bloom, and then decreased. Lipid in fruit mainly distributed in cuticle, tannin layer and parenehyma cells. The cuticle and tannin layel thickness gradually became thin, but no obvious change on the staining of lipid in cuticle and tannins layer was observed during fruit development. The staining of lipid in parenehyma cell became light. The distribution and change trend of polysaeeharide and lipid in bagged fruit were essentially consistent with those in non-bagged fruit, but the staining of polysaeeharide and lipid in bagged fruit was much lighter than that of non-bagged fruit, and the staining of polysaecharide in fruit bagged with three layer bag was much lighter than that in fruit bagged with white one-layer bag from 80 days after full bloom. The rate of browning spot of fruit bagged in white one-layer and three-layer bag were 5.5% and 22.5% respectively, more than that of non bagged fruit. The data suggested that fruit bagging affected accumulation of polysae- charide and lipid, and there was close relationship between the decrease of polysaccharide and lipid and occurrence of browning spot.关键词
