Evaluation of Salinity Stress on Marigold’s Growth with Bacteria Inoculation

This study was performed to Evaluation of salinity stress on marigold's growth with Bacteria inoculation with afactorial experimental design and 3 replications. First factor was bacteria (inoculated and no inoculated) and second factor was salinity stress (control, 2, 4 and 8dS/m). After the experiment, some morphological characters and morphological of marigold were evaluated such as height, yield of fresh and dried flowers, number of flowers per plant, grain yield, petals, seed weight. Totally, it was founded that with increased stress levels from 0 to 8dS, the height, fresh yield of flowers, yield of flower dry weight, number of flowers per plant, grain yield, petals and seed weight, showed 43, 60, 56, 17, 64, 15 and 30percent of reduction, respectively. Also, it was determined that the using of bacteria can reduce the effects of stress on marigold.
