摘　　要：以"大五星"枇杷为材料,调查了露地和大棚果实的生长发育动态,测试了2种栽培模式下的果实品质。结果表明:露地和大棚果实纵、横径生长曲线均呈单"S"型。大棚的果实比露地提早13 d左右成熟。通过品质测试分析得出,露地果实外观表现为近圆形,大棚果实表现为椭圆形;大棚果实的平均单果重比露地重8.7 g左右,可食率高1%左右,可溶性固形物含量高约1.5%,总糖含量高约0.8%,VC含量高约0.03μg/g,总酸含量基本一致。Taking Eriobotrya japonica Lindl as test material, the trends of growth and development of loquat were investigated,compared fruit quality in two different cultivation models, open field and plastic greenhouse. The results showed that the growth curve of loquat fruits presented as a single ＂S＂ according to the data measured by longitudinal diametre and diametre in two cultivation models. The mature date of loquat fruit in plastic greenhouse could be earlier 13 d than that in open field. The fruit appearance looks quite round for plants in plastic greenhouse and oval round for those that in open field according to the data of quality analysis. The single fruit weight in plastic greenhouse was higher 8. 7 g,edible rate higher about 1%, content of soluble solids higher 1.5%, total sugar content higher 0. 8%, and VC higher about 0. 03 ug/g compared to loquats planted in open field. In addition,there was no difference in total acid content for loquats under the two different eultivar conditions.
