Root Architecture Variation in Wheat and Barley Cultivars

Variation in the response of barley cultivars to nirrogen fertilizer

Root Rots of Wheat, Oats, Rye, Barley

The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions. To the many types of root rots in cereal crops many names ha...

Root Architecture Modeling and Visualization in Wheat

This paper aims to develop a root morphological model in wheat (Triticum aestivum L.), and the realistic visualization of root growth under different soil conditions in wheat. Based on the topology of the wheat root system, historical literature and experimental data, a root morphological model in wheat was developed preliminarily using thermal time as a driving factor, including sub-models of ...

Effects of salt Stress on Root Anatomy and Hydraulic Conductivity of Barley Cultivars

A hydroponic experiment was carried out to compare root anatomy and hydraulic conductivity of four barley cultivars including Valfajr, Karoon, Afzal and Zarjo under salt stress conditions. The results showed that under salt stress, the minimum diameter of vessels was observed in the peripheral metaxylem of seminal roots of Valfajr cultivar and in adventitious roots; Karoon with 19±3 µm had maxi...

Root-released organic acids and phosphorus uptake of two barley cultivars in laboratory and field experiments

A major portion of phosphorus (P) applied as fertilizers is bound in soils as P compounds of variable adsorption strength, reducing the effectiveness of P fertilization. Plant genotypes equipped with mechanisms for utilizing the adsorbed P more efficiently can, therefore, enhance the effectiveness of P fertilization. Such genotypes will also enrich plant gene pools for further analysis and upgr...
