Hormones Content in The Developing Cocoa Pods (Theobroma cacao L.)
- Bagikan:
The development of cocoa pods was controlled by hormones, namely gibberelin, auxin, cytokinin and abscisic acid. This experiment was aimed to determine gibberellin, auxin, cytokinin and abscisic acid content in the developing cocoa pods. Two cocoa clones namely KW 163 which represent self compatible clone and KW 165 which represent self incompatible clone were used. Several plants for each clone were selected and hand pollination was conducted before anthesis. Samples of healthy pods were taken at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 week old following hand pollination. Gibberellin, auxin, cytokinin, and abscisic acid content were determined by HPLC (High Performance Liquid Chromatography). The results showed that there was a certain composition in the content of gibberellin, auxin, cytokinin and abscisic acid at each stage of the development of cocoa pods. The composition regulated the metabolism in pods, determined the process of embryogenesis. The results revealed the role of hormones in determining the progress of cocoa pod development.
