Influence of water of the small river of Western Siberia - Ulu-Yul on sprouts of wheat and tomato

Abstract

The some hydro chemical peculiarities of the Uly-Yul River s water (basin Ob) sampled during the spring flood has been demonstrated. In samples of river s water was fixed high level of humic substances concentration: about 23 mg/L humic acids and about 30 mg/L fulvic acids. Ca2+ was a predominant inorganic cation with concentration 0.3 mEq/L. Electrical conductivity of researched water was about 30 μS × cm−1. The sum length of wheat shoots was statistically significantly lower for plants cultivated on Ulu-Yul River s water (experimental group) in comparison with plants cultivated on low concentrated Hewitt nutrition solution (control group). The sum length of tomato roots was statistically significantly bigger for plants cultivated on Ulu-Yul River s water in comparison with plants cultivated on low concentrated Hewitt nutrition solution. Both for wheat and for tomato an increasing of quantity roots/shoots ratio for experimental groups has been demonstrated.
