采用叶面喷布探讨了ＤＥＳ２ 对桃新梢生长的效应。结果表明：１００ ～１ ０００ ｍｇ·ｌ－ １ＤＥＳ２ 对‘Ｂａｂｙ Ｇｏｌｄ ６’桃的新梢生长有抑制效应，且随浓度增高效果增强；同样的趋势也表现在‘砂子早生’桃上。但试验中没有观察到ＤＥＳ２ 对桃新梢生长的促进效应。
The effect of DES2 on the growth of peach shoots was discussed using foliar spray. The results showed that 100-1000 mg · L-1DES2 inhibited the shoot growth of ’Baby Gold 6’ peach and its effect was enhanced with increasing concentration. The same trend was also observed in ’early sand peach’ peaches. However, the test did not observe the promotion of DES 2 on the growth of peach shoots.
