introduction intercropping, the agricultural practice of cultivating two or more crops in the same space at the same time, is an old and commonly used cropping practice which aims to match efficiently crop demands to the available growth resources (agegnehu et al., 2006; dhima et al., 2007). intercropping of chickpea with linseed reduced the chickpea yield by 60.3%, although linseed occupied on...

The objects of research were the first leaves green seedlings spring barley (Hordeum vulgare L.) varieties Belarusian breeding − filmy (Magutny, Raider) and naked (Adamant). Seedlings different age (3, 5, 10 days old) infected with spores fungus Bipolaris sorokiniana (Sacc.) Shoem. a causative agent helminthosporiasis, analyzed 2 after infection. Varietal ontogenetic differences between cultiva...

Immature detached cereal caryopses from barley (Hordeum vulgare L. var distichum cv Midas) and wheat (Triticum aestivum L. cv Sicco) were shown to be capable of fixing externally supplied"'CO2 in the light or dark. Green cross cells and the testa contained the majority of the 14Clabeled material. Some "4C-labeled material was also found in the outer, or transparent, layer and in the endosperm/e...

Environmental stresses are the most important factors that reduce plant growth in stages of development. The presence of aluminum in acidic soils as an environmental stress has an impact on different parts of the plant and reduces root growth, water absorption and nutrients and increases susceptibility to drought.  In order to evaluate the effect of aluminum stress levels on wheat at germinatio...

Wheat yield depends on the number of grains per square metre, which in turn is related to the number of fertile florets at anthesis. The dynamics of floret generation/degeneration were studied in contrasting conditions of nitrogen (N) and water availability of modern, well-adapted, durum wheats in order to understand further the bases for grain number determination. Experiments were carried ou...

the fruit of date palm (phoenix dactylifera l.) is an important horticultural product in the middle east and north africa. among more than 400 reported date palm cultivars in iran, around 20 cultivars are more important due to having better eating quality and trading values. in this study, the fruit of nine commercially important date cultivars including ‘barhee’, ‘breim’, ‘deiri’, ‘fersi’, ‘ga...

twenty-two bread wheat cultivars along with susceptible (sholeh) and resistant (azadi) control cultivars were evaluated for resistance to russian wheat aphid of two growth stages including seedling and stem elongation in greenhouse. five adult aphids per plant were used for infestation. leaf chlorosis at seedling and stem elongation stages and leaf rolling at seedling stage were measured. other...
