Abstract
The current study was carried out on wedge grafting in Mango (Mangifera indica L.) cv. Dashehari during the2022-23 at the Fruit Research Station, Imaliya, Department of Horticulture, JNKVV Jabalpur. This research includes the use of many different plant growth regulators, ZnSo4, and growing conditions. The research was carried out using a statistical design known as Factorial Completely Randomized Design (FCRD).The primary objective of this study is to determine the influence that different scion dip treatments and growing conditions have on the physiological characteristics of the plant. According to the findings, among the various treatments, IAA 200 ppm + ZnSo4 500 ppm under shade net condition was proved superior with respect to maximum chlorophyll content index (27,18.5), leaf area duration (2720.67 cm2/day, 2,620.67 cm2/day), leaf area index (8.65,1035) and light transmission ratio (24.05,18.15) at 60 and 120 days after grafting (DAG). It was also noticed that scion dip treatments with IAA 200 ppm in combination with ZnSo4 500 ppm under the shade net condition were favorable as compared to the open condition.
