APPRAISAL OF SALINITY STRESS TOLERANCE INDUCED BY PACLOBUTRAZOL IN CHICKPEA (Cicer arietinum L.)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 51
Abstract
In the present investigation, it was revealed that treatment with paclobutrazol (PBZ) @ 2.5, 5.0, 10 and 20 µg mL–1 resulted in shoot length and shoot dry weight to decrease significantly under normal condition, but increased significantly in salinity (4 dS m-1 and 8 dS m-1) with respect to control. Treatment with PBZ resulted in a significant increase in root length and root dry weight as compared to control under both normal (PBZ) and saline conditions. Total chlorophyll was recorded to increase significantly at vegetative and flowering stages as compared to control. Hydrogen peroxide decreased significantly at vegetative and flowering stages. Treatment with PBZ resulted in a significant increase in protein and total sugar content at vegetative stage. Proline content decreased significantly at vegetative and flowering stages as compared to control under both normal (PBZ) and saline conditions. Peroxidase, catalase and nitrate reductase activity increased significantly at vegetative and flowering stages as compared to control under both normal (PBZ) and saline conditions.
