The new root formation was higher (51.67-75.00%) in all bacteria strain treatments as compared to control (36.67%). Root and shoot length were longer in cuttings inoculated with&nbsp;<em>Agrobacterium rubi</em>&nbsp;A-16 compared with other bacteria strains. The root and shoot lengths were lower than bacteria treatments in control cuttings. The dry matter content of roots varied from 7.27% (M-3) to 8.33% (A-16). The highest new leaf number (2.97) was counted in TV-6D followed by 2.87 in treatment TV-91C. The leaf area and chlorophyll content varied from 8.41 cm²&nbsp;(control) to 10.32 cm²&nbsp;(M-3) and 22.60 (TV-6D) to 25.97 (TV-91C), respectively. The mean values of examined properties of&nbsp;<em>Epipremnum aureum</em>&nbsp;cuttings treated with auxin-producing plant growth promoting rhizobacteria were better than control. Plus, when bacteria strains were evaluated among themselves, it could be said that the effect of&nbsp;<em>Agrobacterium rubi</em>&nbsp;A-16 on the examined parameters were higher than other bacteria strains and can be suggested for producers of&nbsp;<em>Epipremnum aureum</em> and other ornamental species for vegetative propagation.</p> Agrobacterium rubi, Bacillus megaterium, ornamental plants, propagation Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=AG-20-0093
