Effects of Bacteria and IBA on the Rooting of Citrange Citrus Rootstocks Cuttings

Abstract
In this study, the effects of Agrobacterium rubi A-18 and Bacillus OSU-142 bacterial strains alone and in combination with 1000, 2000, 4000 ppm IBA on rooting of Carrizo citrange and Troyer citrange citrus rootstock in softwood, semi-hardwood and hardwood cuttings were investigated. According to the results, the survival rates and callus formation rates of the cuttings were generally high at the end of the rooting period but the expected results were not obtained. The highest rooting rates in Carrizo citrange cuttings were 4000 ppm IBA and OSU-142 + A-18 (13.33%) in softwood cuttings, 4000 ppm IBA + OSU-142 (20.00%) in semi-hardwood and hardwood cuttings. In the Troyer citrange, OSU-142 + A-18 (6.67%) in softwood cuttings, 1000 ppm IBA in semi-hardwood and 4000 ppm IBA (13.33%) and 1000 ppm IBA in hardwood cuttings, 2000 ppm IBA and OSU-142 (13.33%) the highest rooting has been applications. According to the cuttings pick-up period, the rooting rates of Carrizo citrange are not different between the periods, at the Troyer citrange in the semi-hardwood and hardwood cuttings was higher. As a result, it can be said that plant growth promoting bacteria and IBA applications have no effect on rooting in the softwood, semi-hardwood and hardwood cuttings of the Carrizo citrange and Troyer citrange citrus rootstocks, it can be said that studies on rooting in these rootstocks can be useful in different bacteria strains.
