Correlations study between the selenium content of wheat grass (Triticum aestivum L.) and wheat seeds grown on different soil types

Abstract

In the course of the research we determined selenium and dry-matter content of 35 wheat grasses and 35 wheat seeds. The selenium content of the preparation plant samples was measured by spectrofluorimetric determination (ʎ excitation =380 nm, ʎ emission =519 nm) of the resulted piaz-selenol complex. It was established that between the selenium content of the wheat grass and wheat seed the correlation coefficient was 0.36 at p=0.05 level which indicates a medium close correlation. Similarly, there was a medium close correlation between selenium content of the wheat grass calculated on dry-matter basis and total selenium content of the wheat, with a correlation coefficient of 0.40 at p=0.02 level.
