초록

Healthy seedling generation is the major concern in overcoming adverse effects of biotic and abiotic stresses
during tender stage of development in vegetables and horticultural crops. Because of this, priority is given
to research leading to the generation of healthy seedlings in crops subjected to transplanting and bedding.
In this study, growth pouch experiments were conducted to determine the effect of inoculation of six
different strains of Methylobacterium sp. namely, M. oryzae CBMB20, M. phyllosphaerae CBMB27, M.
suomiense CBMB120, and Methylobacterium strains CBMB12, CBMB15 and CBMB17 on the seedling
development of the vegetable crops cabbage, Chinese cabbage and cucumber; and horticultural crops
tomato and red pepper. Crops treated with the test strains enerally showed higher seedling dry matte
accumulation compared to the control. Significantly higher accumulation was exhibited by CBMB12,
CBMB17, and CBMB20 in cabbage, as well as for CBMB27 and CBMB120 on tomato and Chinese
cabbage, respectively. Furthermore, all the strains promoted root elongation in cucumber and tomato
seedlings while in Chinese cabbage and red pepper, root elongation was observed with CBMB120 and
CBMB12 inoculation, respectively. Large scale nursery study is needed to develop a thorough protocol for
healthy seedling development with the use of these strains.
