A study on the Changes in Isoenzymes of in the Process of ‘Guanxi’ Pummelo Juicy sac Granulation

Abstract

Abstract: The changes in POD, SOD and CAT isoenzyme in the process of pummelo juicy sac granulation were studied. Guanxi pummelo fruits including no-pollinated inbred fruit and pollinated hybridized fruit were experimented to determine isoenzymes by means of polyacrylamide gel electrophoresis. The results showed that the juicy sac granulation indexes of both ‘guanxi-miyou’ pummelo inbred and hybridized rose as the fruits matured, but the former was larger than the latter; 4 POD bands, 6 SOD bands and 3 CAT bands were isolated from inbred juicy sac zymograms respectively, while 2 POD bands, 4 SOD bands and no any CAT bands were separated from hybridized zymograms; POD and SOD isoenzyme were closely related to the juicy sac granulation.
