Abstract:
The four-year-old fragrant pear was used as the experimental material，prohexadione calcium,PBO，paclobutrazol and uniconazol were used as growth inhibitors,different concentrations and spraying times were set up to spray the tree at the vigorous growth stage of new shoots.The changes of length and thickness of one-year-old branches and the effects on the quality of leaves and fruits were investigated,in order to solve the problem of strong tree vigor，branches easy to overgrow，and tree shape was not easy to control of korla pear.The results showed that prohexadione calcium，PBO，paclobutrazol and uniconazole could effectively inhibit the growth of new shoots of Korla pear，and the shoot capping rate increased with the increaing of treatment concentration.After the treatment of prohexadione calcium and PBO，the chlorophyll content of leaves，fruit weight，fruit transverse diameter and soluble solids content were not significantly different from those of the control，and the leaf weight and leaf thickness were significantly higher than those of the control.The fruit longitudinal diameter，fruit shape index and fruit hardness were significantly lower than those of the control.In the production of Korla pear，environmentally friendly and safe prohexadione calcium could be selected as an inhibitor of new shoot growth，and 300-450 mg·L-1 spraying twice was better.
