Abstract:

To investigate the effects of the different fruit- shape agents on fruit quality, 7-year-old “ Tianwang 1” apple trees were studied to use different fruit- shape agents during the flowering. The results showed that the fruit- shape index and the single fruit weight of treatments were significantly higher than the control; The high quality rate treated with 2.8% benzyl ammonium dobutamine gibberellins and ‘Guomeifeng’ solution with 400 times were 95.9% and 96.4%, respectively; The fruit firmness of ‘Guomeifeng’ solution with 300 times, ‘Yiguoling’ solution with 300 times, ‘Baofengling’ + ‘Yiguoling’, BN2 +‘Baofengling’ + ‘Yiguoling’ and other treatments were significantly greater than the control; The soluble solids contents were significantly increased by ‘Guomeifeng’(300 times), ‘Baofengling’ (300 times), ‘Yiguoling’ (300 times, 400 times) and BN2 (300 times, 400 times), but were significantly decreased by 2.8% benzyl ammonia dobutamine gibberellins (200 times, 400 times).
