Effect of mineral nutrition on variability and morphological parameters correlation of Hordeum brevisubulatum (Trin.) Link

The article represents the results of the study of variability structure of morphological parameters and correlation relationship between the parameters of Hordeum brevisubulatum in terms of the levels of mineral nutrition. The results state medium and high level of variability of vegetative organs for all studied variants, while the reproductive organs showed medium and low variability level. The correlation relationship ranges from strong to weak or total absence.
