| Abstract | Since the cutting plants have no root, therefore, they are easily damaged and dehydrate when planted in growth medium. Protection of plants against environmental stress and increasing the sustainability of crop production after cutting propagation are needed. This study was aimed to investigate the effect of alginate bead (containing of Methylobacterium radiotolerans ED5-9 and Streptomyces TM32 fermentation broth as the growing medium) on cutting propagation of Thai herb, i.e. Chaing da, Gymnema inodorum. After 4 weeks of cultivation, the plant cutting tested with alginate bead supplemented with both bacterial fermentations gave higher percentage of survival than the treatment without bead (T10). The T1, 2.60 ml/l of Streptomyces TM32 and 0.25 mg/l of M. radiotolerans ED5-9 fermentation broths blended with 3% alginate treatment presented the highest percentage of survival (90.48ฑ6.56%), rooting (50.00ฑ22.40%) and number of leaves per plant (5.17ฑ0.54). These promising results were obtained when compared with the non-alginate and the synthetic IAA treatments. Therefore, using gelling biocompatibility technique of bacterial fermentation broth could improve organic cutting propagation that was vulnerable to dehydrate and to be infected by pathogens. |
