Influence of bio-regulators on quality of guava (Psidium Guajava L.) Cv. Arka Mirdula and Arka Amulya


Author(s): C Jayalakshmi and Arumugam Shakila

Abstract: The experiment was conducted at Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu, during 2013 to 2015 to find out the effect of bio-regulators on quality of guava cv. Arka Mirdula and Arka Amulya was conducted in Factorial Randomized Block Design with nine treatments and three replications in two seasons viz., June to July and January to February. The treatments consisted of T1- GA3 50 ppm, T2- GA3 100 ppm, T3- NAA 100 ppm, T4- NAA 500 ppm, T5- Brassinosteroids 0.5 ppm, T6- Brassinosteroids 1.0 ppm, T7- Ethrel 500 ppm, T8- Ethrel 1000 ppm and T9- Control (Water spray). The effect of different treatments and varieties were evaluated based on their influence on the quality attributes viz., total soluble solids, ascorbic acid and total sugars. The results of the present study revealed that GA3 50 ppm proved to be the best in increasing the quality characters like TSS, ascorbic acid and total sugars in both the cultivars in both seasons.
