Abstract/Contents: | "Thirty-nine tall fescue varieties, introduces from America, were devided [divided] into five types with the aid of cluster analysis. One was selected as the best representive [representative] in each type, changes of active oxygen and plasma permeability in leaves of different types of tall fescue varieties exposed to different temperature were also tested. The results showed that increasing rate of MDA content were positively correlated significantly with the changes of plasma permeability. With 40°C heat stress, activities of superoxide dismutase (SOD) and peroxidase (POD) were significantly negatively correlated with malonaldehyde (MDA) and plasma permeability (PMP). It also was true in the case of the relationship between catalase (CAT) and MDA, as well as PMP under 0°C stress. Based on the index of active oxygen and plasma permeability, the capability of heat tolerance in the five types of tall fescue was in order: type I > type V > type II > type IV > type III, but it showed some different in cold tolerance as: type I > type II > type III > type V > type IV." |
