Description
Summary:The analysis of the effect of deficiency of mineral elements on a number of traits characterizing morphotypes and productivity of rice varieties of Russian, Italian, and Chinese selection was performed in the study. Russian varieties exceeded all studied foreign variety by the weight of the root system, but they exceeded only Italian varieties by the length of root system. The results of the study demonstrated that the deep root system provides significantly higher productivity of the main panicle of plants under stress (phosphorus deficiency). Phosphorus deficiency increased the length of the root system in both groups with shallow and deep root systems, but the increase was more significant in the group with shallow root system.
