A Comparative Study on the Sugar Accumulation and Composition in the Aril of Litchi from Different Regions
Sugar accumulation and composition in the aril of litchi cvs.Feizixiao(FZX)and Nuomici(NMC)produced from 6 different areas(Guangzhou,Yangjiang,Dongguan,Maoming,Longhai and Taishan)were analyzed.The results showed that the micro-environment and management of different producing areas might influent the aril sugar concentration,but not the sugar compositions in the two cultivars tested.The activities of acid invertas(AI),neutral invertase(NI),sucrose synthase(SS)and sucrose phosphate synthase(SPS)were slightly different,while their gene expressions were unchanged in the arils sampled from different producing areas.
