Sažetak
Phytoplasma-infected and healthy grapevine (Vitis vinifera L. cv. Chardonnay) was treated foliary with indole-3-butyric acid (0.5, 1.0 or 1.5 g/vine). The effect of IBA was examined by testing the grapevine for presence of the phytoplasma 16S rDNA and measuring stress parameters before and after the treatment. Vines treated with IBA showed signs of recovery, but high incidence of natural recovery was also observed among untreated vines in the same experiment. In naturally- recovered untreated plants higher levels of H2O2 were measured while in IBA-treated plants recovery was not correlated with higher H2O2 levels after the treatment. Other biochemical parameters measured, lipid peroxidation and total phenolics, did not show any differences between groups of vines tested. Therefore, further research is required to elucidate the possible effect of IBA on the recovery of phytoplasma-infected grapevine.
