CONTRIBUTION REGARDING THE INFLUENCE OF SIMAZIN TREATMENT ON SOME PHYSIOLOGICAL INDICES TO BARLEY PLANTLETS (Hordeum vulgare L.)

The use of Simazin herbicide to Miraj and to Dana cultivars, in concentration of 0.1%, 0.2%, 0.5% and 1% determinated the variation of some physiological indices. The energy and the faculty of germination decreased to both cultivars, proportionally to the increase of the pesticide concentration. The process of photosynthesis was intensified at the high doses of herbicide also producing the accumulation of total mineral elements.
