【摘要】 以翠玉猕猴桃为试材,系统地研究了大果灵对果实发育、果实品质、贮藏性及枝蔓生长与花芽形成的影响。结果表明,喷施大果灵可使单果重增加约12%,但却显著降低可溶性固形物含量和风味品质,极大地加速贮藏过程中果实软化和腐烂速度,并导致果实变宽和畸形。同时,施用大果灵的植株新梢基部异常膨大,节间缩短,大量基部芽当年萌发,并使翌年新梢上花量大幅度减少。鉴于大果灵对翠玉猕猴桃的严重负面作用,生产上不宜使用。更多还原

【Abstract】 The effects of CPPU on fruit development,fruit quality,storability,shoot growth and flower bud formation were examined systematically on Cuiyu kiwifruit cultivar.While application of CPPU increased average fruit weight by ca.12%,it had a number of adverse effects:it markedly reduced soluble solids content and fruit quality,accelerated fruit softening and fruit rot,and induced formation of widened and misshapen fruit;it caused abnormal thickening,shortening of internodes,and sprouting in the current season of many buds in the basal region of the new shoots;it markedly reduced flower bud formation of the following year.It was suggested that CPPU is not to be used in Cuiyu kiwifruit because of the serous adverse effects.更多还原
