对白梨(Pyrus bretschneideri Rehd.)、砂梨[P.pyrifolia(Burm.f.)Nakai]、秋子梨(P.ussuriensis Maxim.)、新疆梨(P.sinkiangensis Yü)、西洋梨(P.communis L.)以及种间杂交种,共319个品种的石细胞团大小进行分析。结果表明:直径大于250μm的石细胞团约占供试品种总体石细胞团含量的75%以上;直径小于250μm的石细胞团对感官评价果肉质地的影响较小,直径大于250μm的石细胞团含量是影响果肉质地的重要指标。

The stone cells size of 319 pear accessions of 6 Pyrus L.species were analyzed,including Chinese white pear varieties（Pyrus bretschneideri Rehd.）,sand pear varieties[P.pyrifolia（Burm.f.） Nakai],ussurian varieties（P.ussuriensis Maxim.）,sinkiang varieties（P.sinkiangensis Yü）,common pear varieties（P.communis L.）and Pyrus hybrid varieties.The results showed that more than 250 μm diameter of stone cells content accounted for about overall content of 75%;The effects of less than 250 μm diameter stone cells to sensual evaluation is smaller;More than 250 μm diameter of stone cells content is the important indexes to flesh texture.
