Abstract

UV-irradiation of 5-day wheat seedlings was shown to result in the increase in lectin activity. An additional induction of the lectin activity in both stems and roots of seedlings was found after the preliminary treatment of seeds by lectin. The apparent increase in the flavonoid contents in wheat seedlings was marked. The data obtained suggest that the exogenous wheat lectin protects the plants against UV-irradiation at early stage of ontogenesis in doze dependent manner.
Keywords: lectin, lectin activity, flavonoid, UV-irradiation, wheat seedlings
