Roles of Plant Growth Promoting Bacteria on Growth of Ornamental Plants Grown in Anthracene-spiked Soil
Keywords:

This study was performed to determine the ability of plant growth promoting bacteria (Paenibacillus sp. BSR1-1, Streptomyces sp. SRF1, Streptomyces sp. St1 and Streptomyces sp. St8) to stimulate growth of ornamental plants namely Impatiens balsamina L., Tagetes erecta L. and Crotalaria juncea L. grown in 200 mg/kg of anthracene-spiked soils. The results manifested that in the absence of bacterial inoculum, I. balsamina L., T. erecta L. and C. juncea L. grown normally in unspiked soil and anthracene-spiked soil. Using the inoculum of all bacterial strains did not stimulate shoot growth and root growth of I. balsamina L., T.erecta L. and C. juncea L. grown in unspiked soil and anthracene-spiked soil. Applications of bacterial inoculum exert different adverse effect on growth of the plants. For example, Streptomyces sp. SRF1 decreased shoot length and shoot weight of I. balsamina L. grown in unspiked soil and seed of I. balsamina L. did not germinate in anthracene-spiked soil. Paenibacillus sp. BSR1-1 caused shoot length, shoot fresh weight, root length and root fresh weight of C. juncea L. grown in anthracene-spiked soil was lower than that grown without receiving any bacterial inoculum. Streptomyces sp. St1 and Streptomyces sp. St8 caused shoot length of T. erecta L. grown in anthracene-spiked soil were lower than that without receiving any bacterial inoculum.
