Sustainable control of plant diseases can be achieved by developing cultivars with durable resistance. 'Bancroft' barley has durable high-temperature, adult-plant (HTAP) resistance to stripe rust caused by Puccinia striiformis f. sp. hordei. The objectives of this study were to determine the inheritance of the HTAP resistance in Bancroft, develop molecular markers for the HTAP resistance using ...
Cooked grains of ae rice cultivars are too hard and non-sticky due to the presence of long-chain amylopectin, and ae rice cultivars are therefore called ``super-hard rice'' and cannot be used as table rice. However, they are promising in terms of their bio-functionality such as preventing diabetes. Miso (soybean paste) is a yeast-fermented food, made from steamed soybeans, salt, and inoculated ...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
During years 2000 and 2001, biology and population changes of two- spotted spider mite (T. urticae) was studied on five bean cultivars of two species at 25±1ºC temp., 45±4% RH and 15: 9 (L:D) photoperiod, using leaf disks made from 2-, 6- leaf and flowering stages of the plants. The mite mass rearing was carried out on tomato plants under the same environmental conditions and the effects of fee...
Although barley (Hordeum vulgare L.) is regarded as salt tolerant among crop plants, its growth and plant development is severely affected by ionic and osmotic stresses in salt-affected soils. To elucidate the tolerance mechanism, growth and ion uptake of three barley cultivars, differing in salt tolerance, were examined under different levels of NaCl, K/Na and NaHCO3 in the root medium. The cu...
In this experimental, effect of some of antifrost on morphology, anatomy content of selective almond cultivars flower buds of 3 late, medium and early flowering cultivars of almond in Pheranshahr region using factorial design base on complete block randomize with 3 replications was investigated. This region is considerate as cold temperate. Experimental trees were planted with 6×6 m in 2000. In...
introduction barely (hordeum vulgare) is the fourth most important cereal after wheat, corn and rice. regarding the role of breeding to increase barley grain yield a large number of studies have been done in different countries. however, a few studies have been performed across golestan province, in iran. therefore, this study was conducted to know what barley traits have changed with grain yie...
Plants are usually exposed to a range of environmental stresses. These stresses have undesirable effects on survival create growth, quantity and quality of agriculture products. Chilling stress is one of them that can damage cereals at the reproductive stage. The aim of present study was investigation of chilling effects on physiological traits, plant pigments (total, a and b chlorophyll and Ca...
expressed in the lemma/palea would provide molecular clues to the functions of these organs. The lemma and palea (lemma/palea) of cereals are photosynthetic Loss-of-function studies and cloning of floral homeoorgans that supply the developing kernel with carbon and nitrogen. tic genes suggest that the lemma/palea of grasses are Because of their rigid structure, the lemma/palea can also protect ...
Cultivars or species of different plants through physical and biochemical characteristics or indirectly through food diet of host plant can influence behavioral characteristics and efficiency of a natural enemy. This investigation was conducted to determine percentage of parasitism and functional response of parasitoid wasp, Platytelenomus hylas (Hym., Scelionidae) to different egg densities of...
