Electrolyte leakage from leaves and NMR transverse relaxation time (T2) of leaf water were used to differentiate between heat-tolerant (NIAW 845) and susceptible (HD 2428) wheat (Triticum aestivum L.) cultivars. The leaves were exposed to high temperature shock in the range 30 to 55 degrees C and the damage caused, when evaluated by the two approaches was in close agreement. The critical temper...
Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...
The aim of this study was to determine the effects of water stress on the anatomy of xylem and phloem vessels, mesophyll and epidermal cells, relative water content and ion transfer rate of two wheat cultivars including Azar2 as drought tolerant and Shole as drought susceptible cultivars at four leaf stages. Seeds were sown in pots under normal (soil water content at 100% of FC) and the water s...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
sheath blight disease, caused by rhizoctonia solani ag-1 ia, is one of the most serious fungal diseases of rice, worldwide. rice resistance is a relative phenomenon and disease response varied (due to complex quantitative inheritance and high environmental diversity), so an accurate disease assessment would be difficult. to detect a reliable reaction of rice in a high level of disease developme...
in one pole of the continuum of language learning, theoreticians and practitioners traditionally consider english as english as a second language or english as a foreign language. however, in the other pole of this continuum where english is thought of as the most effective tool for international communication, it is referred to as a lingua franca. those who favor an approach to english growing...
This study was carried out on the biochemical aspects of chickpea cultivars and the genomic behavior of A. rabiei pathotypes 4 and 6 in four parts: 1) Determining the number of resistant genes in chickpea native cultivars, 2) Comparing the variation of sodium and potassium electrolytes concentrations in noninfected and infected seedling stems of resistant and susceptible cultivars, 3) Studyin...
abstract this study was conducted to evaluate the resistance of 70 genotypes of barley to powdery mildew. after preparing the samples contaminated with powdery mildew, reproduction of the spores of the fungus was conducted on susceptible cultivar afzal. the experiment was conducted with randomized block design in pot in greenhouse. seedlings were inoculated with the spores fungus in two-leaf st...
Four cultivars and 21 lines of cotton were evaluated for resistance to ramulose (Colletotrichum gossypii f. sp. cephalosporioides) in a field where the disease is endemic. The seeds of each genotype were planted in 5 x 5 m plots with three replications. The lines CNPA 94101 and ‘CNPA Precoce 2’were used as standard susceptible and resistant references, respectively. The disease incidence (DI) w...
the reaction of four field tomato cultivars (super strain b, super chief, mobil, and royal) along with two greenhouse cultivars (polaris and es 1002 f1) was evaluated agianst m. javanica under greenhouse conditions. the soil around tomato seedlings (bearing 5-6 leaves) was inoculated with two levels of the nematode inoculum i.e. 1000 and 2000 eggs as well as second stage juveniles per every kg ...
