Eff ect of triazole compounds on induced changes in growth biomass and biochemical content of white radish (Raphanus sativus L.)

Abstract

Radish (Raphanus sativus L.), belongs to the family Brassicaceae is an important vegetable crop and cultivated all over the India. The tuber of radish is used to prepare the salad and for the preparation of various health dishes. It is rich in vitamin ‘C’ and minerals. It is also used as medicinal properties such as currying liver disorders, jaundice, and various physiological disorders. In the present investigation, the effect of triazole compounds such as triadimefon (TDM) and hexaconazole (HEX) on radish. The plants were given separate treatment with 1 L of water solution containing 20/mg TDM and 1 L of water solution containing 20/mg HEX on 23, 35, and 53 days after sowing (DAS) by soil drenching method. The plants were harvested randomly on 30, 45, and 60 DAS for the determination of growth of tuber, shoot, and biochemical contents viz., starch, protein, and amino acid both in the control and triazole treated plants. From the results it is observed that the triazole treated plants showed pronounced effect in increasing the tuber fresh and dry biomass, protein, amino acid, and starch content in both shoot and tuber tissues of radish, whereas the shoot fresh and dry biomass were decreased when compared to control plants of radish.
