乙烯利和脱落酸对"千层花"和"豫大籽"石榴萌蘖的影响
Effects of Ethephon and Abscisic Acid on Sprouting of'Qiancenghua'and'Yudazi'Pomegranates
摘要
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 al-ways used as cold-tolerance stocks.Then,sprouting numbers and growth was investigated to evaluate the effects of different treatments on in-hibiting pomegranate sprouting.The results indicated that the treatment of 800 mg/L ethephon had the best effects on inhibiting'Qianceng-hua'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.Mean-while,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 sugges-ted applying on'Qiancenghua'pomegranate and 1 200 mg/L ethephon was suggested applying on'Yudazi'pomegranate to decrease workloads of clearing sprouting.关键词
