The Effect of Gibberellic Acid on Development and Respiration of Some Solanaceous Fruits

Abstract

Effect of sprayings of gibberellic acid (GA₁) at anthesis on the development, ripening pattern, and respiration rates of tomato, pepper, tamasango (Jerusalem cherry), akanasu (tomato eggplant), tamago nasu (eggplant), and 'Wase-shinkuro' (eggplant) fruits were studied. GA₁ significantly reduced the size of the tomato, tamago nasu, and 'Wase shinkuro.' No difference in the ripening pattern or in the respiration rates of GA1-sprayed fruits was found.
