Impact of Storage Conditions on Seed Vigor and Viability of Bread Wheat (Triticum aestivum) seeds

Abstract

This experiment was conducted under different storage conditions in the Department of Field Crops, College of Agriculture, University of Anbar in 2019. The objective was to study the effects of storage conditions in seed vigor, viability and field emergence of bread wheat cultivars; Buhooth-22, Adana and Buhooth-158. Seeds were stored for six months under, 5 C°, 25C°, sludge house, and open ceiling frame. Seeds stored at 5C° gave higher values in germination (98.67%), field emergence (93.33%) and coleoptile length (13.99cm). However, there values were not significantly different from those stored at room temperature which gave higher value than the storage method, in radical length, and seedling dry weight. The cultivars were different in all studied traits. Buhooth-158 gave the best values for germination%, radical and coleoptile lengths, seedling dry weight germination vigor, and field emergence. It could be concluded that bread wheat genotypes and methods of storage have significant impact on seed vigor and other related traits.
