| Abstract: | In response to applied PP333 solution on a optimum concentration of 200 mg/L, plant growth and reproductive development of tall fescue( Festuca elata) were inhibited. Treated with the solution, plant root vigor, the number of fibrous root, root to crown weight ratio, chlorophyll a to b content ratio, soluable sugar level in cells and plant stress resistance ability were all increased. |
