【摘要】 在鸭梨果实生长的前中期 ,实施调亏灌溉 ,显著降低了果实的果形指数 ;控水处理期间 ,果实的含水量明显低于对照 ,但并未抑制果实的生长发育或影响果实大小 ;相反 ,对产量、单果重、果实品质及贮藏性有提高的趋势。同时 ,新梢的生长受到显著抑制。更多还原

【Abstract】 Regulated Deficit Irrigation(RDI) was carried out on pear(pyrus bretschneideri var.Yali)at the beginning and in the middle of fruit growth.Results showed that the fruit index(I/D) and fruit water content fell dramatically,while the increase of fruit dry weight (DW)and fresh weight(FW) and the rate of fruit growth were not restrained.In the meantime,there was an obvious tendency that the fruit yield and quality of RDI treatment were raised commonly.And the amount of shoot growth was resetained dramatically.更多还原
