鸭梨是我国特产。为了提高鸭梨品质,七十年代以来,即有不少果树工作者对鸭梨的果形和鸭突(华北农业大学果树教研组等,1979;傅玉瑚等,1990)、田间措施与品质关系(安宗祥等,1089;黄国玺,1988;冉辛拓,1988)、鸭梨黑心病(龚云池等,1986)等方面进行了研究。孙敏等(1983)曾报道了茌梨等4个品种的果点形成过程,而关于鸭梨果点的发育尚未见报道。果点是鸭梨外观的重要因子,为了给提高鸭梨外观品质的技术措施提供依据,1989～1990年对鸭梨的果点发育进行了初步研究。
Pear is our specialty. In order to improve the quality of pear, since the 1970s, many fruit-tree workers have noticed that the fruit shape and duckblight of pear (North China Agricultural University Fruit Research Group et al., 1979; Fu Yuhu et al., 1990) Zong Xiang et al., 1089; Huang Guoxi, 1988; Ran Xin Tuo, 1988), black pear heart disease (Gong Yunchi et al., 1986). Sun Min et al. (1983) reported the formation of the fruit of four varieties, including pear, while the development of the fruit of pear has not been reported yet. Fruit point is the appearance of pear an important factor, in order to improve the appearance of pear quality technical measures to provide the basis of 1989 to 1990 on the pear fruit development were studied.
