The climate, together with all factors contained, influences the life of plants, imposing the development of a distinctive study of these relations assumed by agrometeorology. Outside considerations of a theoretical general manner, we took into account the fact that the temperate climate conditions from Romania, the plants, have adapted their life cycle to the season rhythm, responding to the influences of external factors, in relation to their reaction norm, as a result of the interaction between the genetic information and the factors of the external environment. The agrometeorology, as a science, analyzes the permanent interaction between the weather factors and the vegetable organisms, their positive or negative influence on the physiological processes and on their life phases. The agrobiometeorology has three study directions: the physiological one, the phenological one, and the species’ pathology, analyzing the weather conditions and their implications in the morpho-physiological conditions, following the evolution of relations between weather – climate – plant – production .
