| Abstract:
Production of seedless table grapes includes application of gibberellic acid (GA3) to attain adequate berry growth and quality. Additional berry size increases can be obtained with CPPU. In this experiment, a novel compound consisting of a mixture of different gibberellins (GAs) was tested along with GA3 and CPPU applications. GAs-treatment alone determined a significant increase in berry size and bunch weight as compared with GA3-treatment. Inclusion of CPPU resulted in an additional increase in berry growth when added both to GA3 and GAs, with a reduction in berry drop. Increases in berry growth resulted in retarded soluble solids accumulation and later harvest. Further quality factors and possible usage regarding this new bioregulator are discussed. | |
