Abstract
Ion (Na+ and Cl-) exclusion and upregulating antioxidant activities in mango scion cultivar through grafting on salt tolerant rootstocks could extend the mango cultivation in salt affected area with commercially viable production. Thus, the selection of rootstock-scion combinations with enhanced tolerance to salinity requires a better understanding of rootstock influence on ion exclusion and biochemical changes. To achieve this goal, two polyembryonic, Olour and Kurakkan and one monoembryonic viz., non-descript seedling (common mango rootstock) grafted with the scion Amrapali were tested under NaCl stress. Grafted plants were irrigated with water containing 0.0 or 50 mM NaCl at four days interval for 90 days. In the tested rootstock-scion combinations, minimum reduction in plant height and leaf numbers under salinised condition was found in graft with non-descript seedlings and Olour rootstocks, respectively. However, malondialdehyde (MDA) content and catalase (CAT) activity were similar in all rootstock-scion combinations. The higher peroxidase activity (213.43 Ab560 U g-1 leaf fresh weight) and proline accumulation (215.98 mug g-1 of fresh weight) was observed in plants grafted with Olour rootstock. Graft with non-descript seedlings had reduced accumulation of Na+ in leaf concentration while graft Olour inhibited the accumulation of leaf Cl- concentration in the presence of NaCl. Olour seems to be good Cl- excluder rootstocks while non-descript seedling could effectively exclude Na+ from leaf tissues of scion cultivar.
