Abstract: Maize seeds were soaked in the solution of extracts of Peganum multisectum Maxim Bobr to study thew effect on seedling growth and cell protective enzyme system. The results showed that the germination of maize seeds and activity of α-amy lase were suppressed apparently by treatment and with increasing this in the concentration of extracts the cultural time sharply increased or prolonged. With the time of culture prolonged, the vigor of roots and activity of nitrate reductase in leaves were raised, impel the growth of plant with the dry matter weight of roots and shoot increasing and the ratio of root to shoot rising. The activity of catalase(CAT) and ascorbic acid oxidase(ACO) in leaves were reduced apparently, the activity of peroxidase(POD) was increased, impelled the quantity expression of isoperoxidase patterns in root and lea.f.

Key words: maize, Peganum multisectum, vigor of roots, protective enzyme, isoperoxidase
