The physiological and molecular bases for contrasting [alpha]-amylase phenotypes were examined in germinating seeds of two barley (Hordeum vulgare L.) cultivars, Morex and Steptoe. Morex is a high-quality malting barley that develops high [alpha]-amylase activity soon after germination. Steptoe is a feed barley that develops only low [alpha]-amylase activity levels during this period. The expre...
Net blotch, caused by Pyrenophora teres Drechs. (anamorph: Drechslera teres (Sacc.) Shoemaker), is a prominent foliar disease of barley (Hordeum vulgare L. emend. Bowden) in Western Australia (19,46), as well as elsewhere in the world (13,28,31,34,39,41). Two types of leaf symptoms are associated with the net blotch disease: the net type, caused by P. teres f. teres, which causes horizontal and...
Barley (Hordeum vulgare L.) is an important cereal crop, but its sustainable production significantly hampered due to the presence of various edaphic stresses. Understanding variability in root morphological traits among diverse barley genotypes critical for selecting those with suitable breeding new cultivars better adapted stress environments. Root early growth stage (30 days after transplant...
Quantifying genotype × environment interaction effect and yield stability under different environmental conditions is very important challenge in plant breeding programs. The aim of this study was to quantify genotype × environment interaction effect on grain yield and grain yield stability of barley promising lines in temperate regions of Iran. Nineteen promising barley lines (G1-G19) along wi...
effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university in 2013-14. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars (ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) an...
to better understanding of drought resistance features including tolerance to chemical desiccation and transient photosynthesis under soil moisture stress in triticale in comparison with wheat and barley, an experiment was conducted during year 2009-10 in grizeh agricultural research station located in sanandaj. effect of three soil moisture regimes including irrigation in soil water potential ...
This research was carried out to determine effect of sorghum cultivars and copper foliar spray on physiological traits under saline water situation via split plot experiment based on randomized complete blocks design with four replications during 2015 and 2016 year. The main plot consisted sorghum cultivars at three level (Kimia, KGS10, KGS4) and Copper foliar spray (C1: 0 or control...
In order to study the effects of salt stress on yield and yield components, 21 rice genotypes, in a factorial experiment were conducted based on Randomized Complete Block Design with 3 replicates on pots in greenhouse at Sari Agricultural Science and Natural Resources, during 2009. Salt stress was applied on reproductive stage in rice at 3 levels 0, 6 and 10 ds m-1 NaCl. Results showed that t...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
