The Mechanism of Action of Liquid Seaweed Extracts in the Manipulation of Frost Resistance in Winter Barley (Hordeum vulgare. L) By Stephen Burchett Frost assays carried out on winter barley (Hordeum vulgare cv Igri) showed that a single (IOml I) application of liquid seaweed extract (LSE) marginally increased the frost resistance of non-acclimated (NA) plants by 2.3% compared to NA controls an...

Recent progress in the characterization of two groups of genes responsible for natural differences in frost tolerance inwheat and barley is reviewed here. The first group includes the vernalization genes that delay flowering until the end of the winter and protect sensitive floral primordia. This process is regulated mainly by differences in the regulatory regions of VRN1 and VRN3 genes or in t...

Abstract Freeze–thaw damage and the lack of aggregate resources have become two major problems facing construction industry. The use recycled to produce concrete has good social economic value. In this study, author used coarse as a substitute for stone mix concrete. order enhance performance concrete, microwave heating modification process was introduced 0.10% volume fraction polypropylene fib...
