Variability of ontogenesis morphological-physiological attributes of short-awn barley and meadow grass in natural conditions

In work are described the ontogenetic measurements of morphological-physiological indicators at species of short-awn barley and meadow grass in different age conditions. We gave spent daily supervision of net-photosynthesis at 2 kinds of plants - representatives of basic types II over-inundated terrace. De-pendence of net-photosynthesis indicators from age conditions of plants is established.
