Abstract:
Ten-year-old ‘Huangguo Pear’ was used as material，the growth rhythm was studied and regression curve was fitted to further clarify its branches and fruit growth rules，so as to provide the oretical basis for production.The results showed that the annual growth of the branches of ‘Huangguo Pear’ was fast at first and then slow.Fruit development go through four stages,rapid growth stage，slow growth stage，rapid growth stage before fruit ripening and slow growth stage before fruit harvest.Logarithmic model is the best fit for growth of vegetative branch length of ‘Huangguo Pear’，H=0556ln(t)+2192.Quadratic model is the best fit for vegetative branches growth of roughness，D=-1E-05t2+0003t+0362.Quadratic model is the best for the growth of pear fruit vertical and horizontal diameter，Z=0000t2+0047t+1054 and H=0000t2+0037t+0884.
