摘　　要：研究了前期喷施低浓度乙烯利和采前喷施高浓度乙烯利对黑穗醋栗“黑珍珠”果实品质的影响。结果表明 :在正常采收期前 2 5d喷 1～ 2次 10 ,5 0 ,2 0 0mg/L乙烯利溶液 ,对果实中还原糖、总糖、维生素C和色素含量的增加以及有机酸含量的降低都起到了促进作用。采前 2～ 4d喷施 2 6 7,5 0 0和 10 0 0mg/L乙烯利溶液 ,只对色素含量增加起到了明显的促进作用 ,而对糖。Effect of foliage applicationethephon of various concentrations on fruit qaility black currant( Ribes nigrum L.) cultivars “Ben Lomond” was studied. Treatments of 10,50 and 200?mg/L liquid of ethephon,which were applied once (June 25) or twice (June 25 and July 1),enhanced contents of reducing sugar,total sugar,Vc and pigment and decreased content of organic acid. Treatments of 267,500 and 1?000?mg/L liquid of ethephon,which applied 2～4 d before regular harvest period,only increased the content of pigment apparently and had no effect on the contents of sugar,organic acid and Vc.
