Heavy metals are one of the major ecological problems for all living beings, accumulating more and more in surroundings such as soil, water and air. It also causes severe harm to plants, primarily causing deteriorations in growth and development, and in advanced cases, the death of the plant. One of these heavy metals is lead. It is an element that reaches soils mostly through the automobile industry and through the use of leaded pesticides and it is not essential to plants, but rather negatively affects growth and development. The purification of soils contaminated by heavy metals is not possible especially in the short term. Because of these reasons, it is extremely difficult to remove the heavy metal contamination in the soil. Some rhizobacteria living freely in the soil affect plant development due to their functions such as making phytohormone and vitamin synthesis, inhibiting ethylene synthesis, enhancing stress resistance, facilitating nutrient intake and phosphate resolving. Some rhizobacteria were detected to be able to reduce heavy metals to less toxic forms. With this research, it was aimed to determine the effects of PGPR applications on lead (Pb(NO3)2) stress in Alphonse Lavallee grapevine variety grafted on 1103 Paulsen grapevine rootstock. For this purpose, lead (10 and 25 ppm Pb(NO3)2) was added to both environments with PGPR inoculated and uninoculated plants, some physical (shoot length, shoot weight and average number of leaves per shoot) and biochemical analyses (chlorophyll content, degree of membrane damage, proline, total phenolic content, lipid peroxidation and mineral content) were made. As a result of the research, PGPR applications were found to be extremely effective in preventing heavy metal stress caused by lead or in mitigating the stress severity.
