| Abstract: |
| To solve the problem of vigorous vegetative growth and reduced fruit quality of figs in southern Xinjiang, this study used the biennial fig (Ficus carica L.) ‘Bojihong’ variety as the test material and used clear water as the control (CK). During the shoot growth period, different concentrations of pleotropic azole were applied to different parts of the plant. The treatments included Y1 (Blade application with 15 mg·L-1), Y2 (Blade application with 45 mg·L-1), Y3 (Blade application with 75 mg·L-1), J1 (Stem application with 15 mg·L-1), J2 (Stem application with 45 mg·L-1), J3 (Stem application with 75 mg·L-1), D1 (Terminal bud application with 15 mg·L-1), D2 (Terminal bud application with 45 mg·L-1), and D3 (Terminal bud application with 75 mg·L-1). Plant growth and fruit quality and sugar acid components were analyzed. The results showed that: (1) Pleotropic azole could significantly inhibit shoot growth, of which J3 was the most significant effect of 34.99% compared with the control. And the inhibitory effect was enhanced with the increasing concentration. (2) The application of 45 mg·L-1 pleotropic azole to the stem could significantly increase the single fruit mass by 13.40%. The application of 75 mg·L-1 pleotropic azole promoted the accumulation of soluble solid and soluble sugar content in the fruit, which increased by 21.04% and 26.83% with the control and reduced the titrated acid content by 16.67%, and the fruit sugar\|acid ratio increased by 63.38%. (3) Low concentration (15 mg·L-1) promoted the accumulation of the total sugar fraction of fig, which increased by 12.70% compared with the control, inhibited the accumulation of 0.32% of the fig acid fraction, and high concentration (75 mg·L-1) treatment promoted the accumulation of 11.78% quinic acid in the fruit. (4) Principal component analysis showed that the comprehensive score of each treatment was Y3> D3> J2> J3> CK> Y1> J1> D2> Y2> D1. In conclusion, high concentration (75 mg·L-1) significantly improved the fruit quality of ‘Bojihong’ figs, and foliar application of 75 mg·L-1 was the best. |
