不同砧木对凤梨释迦‘吉夫纳’品种生长发育和果实品质的初步研究.

[Objective]To provide scientific references for the screening of suitable Annona atemoya Hort. cv. ’ Gefner’ in central and southern Guangxi, the effects of different rootstocks on the growth, development and fruit quality of Atemoya were studied. [Methods] Bullock’ s heart, Thin scale, TD No. 2, Cherimolia and’African Pride’ were selected as rootstocks to study the effects of different rootstocks on the survival rate of seedling grafting, field growth potential, fruit yield and quality. [Result] The results showed that the survival rates of seeding grafted with different rootstock panicle combinations were above 80 % and had strong grafting affinity, the rate of growth potential, fruit yield and quality of the grafting plants were different according to the stock. The comprehensive performance of Bullock’s heart, Cherymoya, ’African Pride’ were better than those of Thin scale and TD No. 2. [Conclusion] According to the comprehensive evaluation, Bullock’ s heart, Cherymoya and ’ African Pride’were suitable to be used as the grafted rootstock varieties of Atemoya in the central and southern Guangxi.
