Abstract:
This two year experiment were carried out in earthen pots during 2018-20 under cage house, Department of Plant Physiology, S.K.N. College of Agriculture, Jobner. The Ziziphus rotundifolia root stock of ber planted in pots. The recommended doses of FYM, fertilizers and other inputs provided at proper time. These Plants were salt stressed by applying saline irrigation water of EC=Control (Tap water), EC= 8.0 and EC= 16.0 dSm^-1 as and when required after establishment in pots. The plants were foliar sprayed by three concentration of Ascobin i.e. 0, 400 and 800ppm. A significant increase were recorded in the proline content, cell membrane injury and hydrogen peroxide content in the plant leaves under increasing level of salinity as compared to control, whereas a significant decrease were noticed in these traits by the foliar spray of Ascobin up to 800ppm concentration. A significant increase were also noticed in ascorbic acid content and Superoxide Dismutase (SOD) Activity in the plant leaves under increasing level of salinity as compared to control with a significant increase also in these parameters by the foliar spray of Ascobin up to 800ppm concentration.
