The study was conducted to investigate the effects of abuscular mycorrhiza (AM) fungi on the growth and development of oneyear-old cherry (Prunus pseudocerasus) seedling. 50, 100 and 150 mL AM fungi were respectively applied into surroundings of root system when cherry seedlings were transplanted. The results showed that AMfungi significantly enhanced the colonization rate in the root and the maximum values of which appeared at 120 days after AMfungi applied, were 17, 18 and 23 times in comparison to the control. After AMfungi colonization in the roots, the activities of phosphatase, urease and invertase enzymes and available nitrogen, phosphorus and potassium concentrations in rhizosphere soil markedly increased and positive trend was found between effectiveness and application quantity of AM fungi. Compared to control plant, AMfungi improved the activities of CAT and SOD enzymes but decreased MDA content. Due to enhancement
of soil and tree's nutrients, the survival percentage of cherry seedling was both 100%for 100 mL and 150 mL treatments. It is therefore proposed that 150 mL AMfungi per tree was the best choice for the growth and clevelopment of cherry seedling. |
