Enhancement of Drought Resistance in Wheat and Corn by Nanoparticles of Natural Mineral Analcite
Journal Title: Ecologia Balkanica - Year 2014, Vol 6, Issue 1
Abstract
The effect of the application of nanoparticles of analcite to soil (at 0, 500, 1000 and 1500 mg L[sup]-1[/sup]) on drought resistance of wheat and corn seedlings was studied in pot experiments. The dependence of the analcite effect on soil moisture level and type was also evaluated. For this, three levels of soil moisture were modeled: 20%, 40% and 60% field capacity. The following types of soils were studied: greenhouse soil mixtures, gray podzolic and sandy soils. The positive effect has been established for all doses of analcite tested: seed germination, seedlings growth criteria as well as content of photosynthetic pigments increased, while characteristics of water balance less deviated from the norm under water deficit. Application of analcite caused sharp accumulation of protective antioxidants (flavonoids, carotenoids) and activation of catalase (in corn) under soil drought. While proline content decreased. The dependence of analcite effect on its dose, soil moisture level and type as well as species of tested plants was discussed.
