Abstract:
The present experiment was conducted at Department of Horticulture, VNMKV, Parbhani during the year 2020-2021. The pot experiment was laid out in Factorial Randomized Block Design which was replicated twice with two factors, i.e., Grafts, and Salinity levels. In grafts, there were 4 varieties grafted on Solanum torvum i.e., Phule Arjun, Phule Harit, Krishna and Manjari Gota by adopting cleft method and there were 5 salinity levels i.e., 0, 2, 3, 4 and 5 dSm^-1 which was imposed with the help of Sodium chloride (NaCl) salt to assess the response of rootstock towards the chlorophyll characteristics under various salinity stress conditions. The results revealed that among the grafts, significantly the maximum chlorophyll-a, b and total chlorophyll content was observed in Phule Arjun grafted on Solanum torvum (92.08, 39.63 and 131.70 mg^-100g, respectively) whereas, for CSI was found in Phule Harit grafted on Solanum torvum (98.18%). Phule Arjun grafted on Solanum torvum was proved to be maximum for chlorophyll-a at 3.00 and 4.00 dS m^-1 (93.22 mg^-100g and 90.20 mg^-100g, respectively) but at 5.00 dS m^-1 it was Krishna grafted on Solanum torvum (88.63 mg^-100g). Phule Arjun grafted on Solanum torvum was proved to be maximum for chlorophyll-b at 4.00 and 5.00 dS m^-1 (39.19 and 38.76 mg^-100g, respectively) but at 3.00 dS m^-1 (40.63 mg^-100g) it was Krishna grafted on Solanum torvum. Phule Arjun grafted on Solanum torvum was proved to be maximum for total chlorophyll at 3.00, 4.00 and 5.00 dS m^-1 (133.01, 129.38 and 126.90 mg^-100g respectively). Phule Harit grafted on Solanum torvum was proved to be maximum for chlorophyll stability index at 3.00, 4.00 and 5.00 dS m^-1 (98.28, 97.28 and 96.30%, respectively).
