PP333(Paclobutrazol)是一种强烈的生长延缓剂,已知对多种水果的成熟有关。本试验旨在探明PP333作采前处理对芒果釆后成熟特性、酶活性以及果实品质的影响。 用印度勒克瑙北部平原园艺研究所试验农场的15年生Dashehari芒果嫁接树为试材,于1987年10月15日花芽分化期和1988年5月13日采前20天,用脚动喷雾器喷施浓度为250、500、1000、2000和3000mg/l的PP333至药液从植株滴下为止。每个处理均加入0.1％Teepol作为表面活性剂,对照树仅喷含0.1％Teepol的水溶液。试验采用随机
PP333 (Paclobutrazol) is a potent growth retardant known to be involved in the maturation of many fruits. The purpose of this experiment was to determine the effect of PP333 preharvest treatment on ripening characteristics, enzyme activity and fruit quality of mango. Fifteen-year-old Dashehari mango grafted on a pilot farm in Northern Plains Horticultural Research Institute, Lucknow, India, were used as test materials for flower bud differentiation on October 15, 1987 and 20 days prior to harvest on May 13, PP333 at concentrations of 250, 500, 1000, 2000 and 3000 mg / l until the liquid drops from the plant. Each treatment was supplemented with 0.1% Teepol as a surfactant, and the control tree was sprayed with only 0.1% Teepol in water. The experiment was random
