Abstract
This research investigated physiological and biochemical changes at rootstock-scion union of graft combinations between Iranian rootstocks and Asgari scion in response to NAA and BAP application. Grafting cuts of scion and rootstock were dipped into NAA (0, 200 and 400âmgâ
Lâ1) and BAP (0, 250 and 500âmgâ
Lâ1) solutions for 30âmin, immediately after the cuttings were grafted using the wedge grafting technique. The highest successful grafting rate (82%) was recorded with Asgari-Asgari combination treated with 200âmgâ
Lâ1 NAAâ+â500âmgâ
Lâ1 BAP. Treating the graft cut-surfaces with 200âmgâ
Lâ1 NAAâ+â500âmgâ
Lâ1 BAP caused the lowest H2O2 and MDA contents. Among all the graft combinations, the highest increase in chlorophyll content with a high photosynthesis efficiency occurred in Asgari-Shahani when treated with 200âmgâ
Lâ1 NAAâ+â500âmgâ
Lâ1 BAP. The graft union formation in the presence of 200âmgâ
Lâ1 NAAâ+â500âmgâ
Lâ1 BAP application enhanced CAT and POX activities. In conclusion, treatment of graft zone with 200âmgâ
Lâ1 NAAâ+â500âmgâ
Lâ1 BAP enhanced antioxidant activities and reduced lipid peroxidation in scion leaves. However, several grapevine rootstocks tested in our research were also impacting the scion performance.
