Effects of Flowering Biology and Pollination Methods on Fruit Development of Camellia oleifera
To investigate the effects of flowering biology and pollination methods on fruit development of Camellia oleifera,healthy 14-year-old cutting seedlings of national approved varieties'Changlin 4'(CL4)and'Changlin 53'(CL53)were used to statistically analyze the flowering phenology and floral organ structure characteristics,as well as the variation of basic fruit and economic traits of mature fruits under natural pollination,self-pollination and cross pollination.The results indicated that:① CL4 is an early flowering variety.CL53 is a mid-flowering variety.There are numerous mid-flowering varieties with fre-quent insect pollination,which is conducive to spread of the pollens.The flowering characteristics of CL4 are more conducive to self-pollination.② Dynamic analysis of transverse diameter and vertical diameter revealed that in the same time period,the transverse diameter and vertical diameter of CL53XCL53 were the smallest,and the variation was significant.There was no significant difference between CL4XCL4 and cross pollination.③ The comparison of fruit traits revealed that after self-pollination,the average number of seeds,fresh seed weight,transverse diameter and vertical diameter of CL53 fruits decreased significant-ly,while there was no significant difference in all pollination combinations of CL4 fruits.④ To gain insights into ranking of economic traits,Membership Function were utilized,in all pollination combina-tions,CL4×CL4,CL53×CL4,CL4×CL53 was ranked first,second,and third,respectively.In sum-mary,CL53 has obvious advantages in cross pollination,but CL4 self-pollination has great potential appli-cation value.In addition,CL4 and CL53 can cross pollinate each other as parents,and the pollinated fruits showed excellent quality,which has great potential for promotion and application.
