Abstract:
Taking three sweet cherry as materials，the effects of different concentrations of CCC and B9 by spraying on the leaf on three cultivars were compared and studied，in order to provide reference on controlling excessive growth of sweet cherry in greenhouse.The results showed that the plant height was decreased and the stem diameter was increased by spraying of CCC and B9，and the effects of inhibition strengthened with the concentration increasing.The optimum treatment of two growth retardants was 4 000 mg/L.The plant height of ‘SUM’ and ‘AN’ and ‘MZ’ were respectively decreased by 28.5%,27.4% and 18.4%，and the stem thickening were respectively increased by 24.7%,25.3% and 24.4% in the condition of 4 000 mg/L for CCC.The plant height of three sweet cherry cultivars were respectively decreased by 36.9%,35.2% and 36.2%，and the stem thickening were respectively increased by 26.7%,27.71 and 25.6% when they treated with B9 under 4 000 mg/L.The dwarfing effects of ‘SUM’ and ‘AN’ were stronger than those of ‘MZ’ when they treated with CCC of the same concentration.The effects of B9 on plant height were larger than those of CCC，but the effects of CCC and B9 on stem thickening of three cultivars were the same.
