Abstract:
The wild type 6421 and its semi-dwarf mutant E483 were used as the test materials to observe the effects of gibberellin treatment on fruit phenotype and physiological characteristics.Different concentrations (0，10，20，40，60，80，100 mg·L-1) of GA3 were used to continuously spray the young fruits of 6421 and E483 for 15 days，in order to provide reference for the subsequent understanding of the mechanism of pepper fruit mutation regulated by GA3.The results showed that compared with 6421，E483 had smaller fruit，shorter fruit stalk，significantly lower single fruit weight.The contents of four quality indicatorss (soluble sugar，soluble protein，vitamin C and cellulose content) and the activities of three antioxidant enzymes (CAT，POD，GR) activity were significantly increased，while the MDA content was significantly decreased in E483 fruits.GA3 treatment could promote the fruit development of 6421 and E483.The fruit length，fruit width，fruit stalk width and single fruit weight all increased while the fruit stalk length first increased and then dropped slightly with the increase of GA3 solution concentration.When the GA3 spray concentration was 80-100 mg·L-1，the phenotype of E483 fruit could return to the phenotype of wild type 6421 control.At the same time，GA3 treatment could also improve the intrinsic quality and stress resistance of the fruits of 6421 and E483.As the concentration of GA3 solution increased，the soluble sugar，soluble protein and vitamin C content in both fruits first increased and then slightly decreased，the cellulose content continued to increase，the CAT and POD activities increased or first increased and then decreased slightly，and the GR activity first increased and then decreased slightly，while the MDA content kept decreasing.
