Abstract:
Taking 16-year-old ‘Red Fuji’ apple and 8-year-old Red peeled pear as the test material，used cyanamide，urea，thiourea，lime sulfur，TMN-6，CFA and NAA and Eth as the chemical thinning agents for ‘Red Fuji’ apple and Red Peeled pear.Randomized block design method was used.The suitable chemical thinness to apple,pear for kunming area and their mechanism as well as their influence on embryology were stuided.The results demonstrated that,one week after spraying lime sulfur at 1.5°Be，the flower-setting of inflorescence was 10.1 percent point lower than control in Red peeled，it had a significant effect and its proportion of single inflorescence was 87.92%.After physiological fruit drop，the treatment of 0.25% thiourea’s flower-setting of inflorescence compared with control was reduced by 21.6% and the proportion of single inflorescence was 94.49% in Red peeled.TMN-6 at the concentration of 0.3% was appropriate for the chemical thinner of Fuji apple and improved the longitudinal，transverse fruit diameter and fruit weight to some extent.TMN-6 made an effect though burning the petals，anthers and stigma，and killing some part of pollen andrestraining the pollen tube growth.CFA thinned flower by injuring pollen tube and stigma and the mechanism of thiourea was based on restraining the pollen tube growth which was in the upper part of stigma.Spraying lime sulfur，pollen germinated was normally on stigma，but it had visible restraint to the growth of pollen tube.
