Abstract:
Effects of auxin and gibberellin on changes in pectin polysaccharides and activities of the enzymes, pectin methylesterase and polygalacturonase were assayed in fruits of cape-gooseberry (Physalis peruviana L. 'Rashbhori') during their development and ripening. The water-soluble pectic fractions accumulation more in the auxin-treated fruits than in the control, while gibberellin raised the level of the acid-soluble and alkali-soluble fractions. Treatments with auxin increased polygalacturonase activity and gibberellin proved to be highly effective in reducing its activity. The significance of these findings in relation to pectin solubilization is discussed.
