【摘要】 为了提高石榴除萌效率，促进石榴省力化栽培，采用不同浓度乙烯利和脱落酸处理抗寒砧木“千层花”和“豫大籽”石榴主干基部(以清水处理为对照),通过调查萌蘖数量及其生长情况，比较不同处理对石榴萌蘖的抑制效果。结果表明，800 mg/L乙烯利处理“千层花”石榴主干基部对萌蘖抑制效果最好，不仅有效推迟了其萌蘖芽发生时间，处理后27 d时，平均萌蘖芽数量和萌蘖芽长度分别显著低于对照100%和100%,且萌蘖新梢叶片数量、长度和宽度均显著较低；1 200 mg/L乙烯利处理“豫大籽”石榴主干基部对萌蘖抑制效果最好，至处理后27 d时，其平均萌蘖芽数量和萌蘖芽长度分别显著低于对照95.7%和94.5%,但对萌蘖新梢叶片数量、长度和宽度只在处理后前21 d有抑制效果。因此，推荐使用800 mg/L乙烯利处理“千层花”石榴，使用1 200 mg/L乙烯利处理“豫大籽”石榴，以减少除萌工作量。更多还原

【Abstract】 The study aims to improve the efficiency of clearing pomegranate sprouting for helping labor-saving cultivation of pomegranate. The ethephon and abscisic acid of different concentrations were applied to trunk bases of ‘Qiancenghua’ and ‘Yudazi’ pomegranate, which are always used as cold-tolerance stocks. Then, sprouting numbers and growth was investigated to evaluate the effects of different treatments on inhibiting pomegranate sprouting. The results indicated that the treatment of 800 mg/L ethephon had the best effects on inhibiting ‘Qiancenghua’pomegranate sprouting, which put off sprouting occurring time. The average numbers and lengths of sprouting buds on trunk bases of ‘Qiancenghua’pomegranate were 100% and 100% significantly lower than the control at 27 days after the treatments, respectively. Meanwhile, the average leaf numbers, lengths and widths of sprouting shoots were also significantly lower. The ethephon treatment of 1 200 mg/L had the best effects on inhibiting ‘Yudazi’pomegranate sprouting. The average numbers and lengths of sprouting buds on trunk bases of ‘Yudazi’pomegranate were 95.7% and 94.5% significantly lower than the control at 27 days after the treatment, and leaf average numbers, lengths and widths of their sprouting shoots were not effectively inhibited from 21 d after the treatment. Thus, 800 mg/L ethephon was suggested applying on ‘Qiancenghua’pomegranate and 1 200 mg/L ethephon was suggested applying on ‘Yudazi’pomegranate to decrease workloads of clearing sprouting.更多还原
