Abstract
Roses (Rosa spp.) are considered as poplar ornamental plants for urban landscape with their pretty petals and used for beautification in public gardens and improving the environment. Trichoderma harzianum was applied to various plants as a potential bio-control agent helping plants to resist pathogens. In our study, three native strains of T. harzianum were inoculated together on the soil in the pots of planting R. chinensis ‘Shi-Jie-Mei’ (the Ten-sisters Roses) and compared with that of no-inoculated to find their changes in growth traits. Analysis results showed that many traits, including the number of branches, the height of stems, fresh weight, dry weight, the water content in leaves and stems, were significantly increased. It was found that antioxidant enzyme activities-catalase, peroxidase, and superoxide dismutase in leaves were also significantly increased compared to the CK. In addition, hormone levels, such as salicylic acid, indole-3-acetic acid, gibberellins, jasmonic acid, zeatin, and abscisic acid in leaves were enhanced significantly induced by T. harzianum. Our results indicated that T. harzianum could improve the growth traits of the rose by regulating antioxidant enzyme activities and phytohormones level.
