One-and-a-half-year-old Kinnow plants budded on Jatti Khatti were treated with different triazole compounds in the presence or absence of NaCl. All of the NaCl damage symptoms were alleviated by the triazoles. The maximum improvement in leaf weight ratio (LWR) (40.9%), membrane stability index (MSI) (1.2-fold), and relative water content (RWC) (1.1-fold) was found in paclobutrazol (PBZ)-treated plants in the presence of NaCl. Furthermore, hexaconazole (HEX) and PBZ plants had lower accumulation of Na ⁺ in leaves while less Cl ⁻ content and maximum K ⁺ content in leaf tissues were found in PBZ-treated plants under NaCl stress condition. Thus, PBZ and/or triazole (TRZ) could be used as a potential tool to enhance salinity stress tolerance in Kinnow budded on Jatti Khatti.
