Genetic relationships between plant height and root morphology were investigated in a diverse set of wheat germplasm [199 double-haploid progeny derived from a cross between Avalon and Cadenza (Triticum aestivum L.), Rht near-isogenic lines (NILs), and accessions from the Watkins Collection] to investigate whether Rht genes controlling shoot height also control seedling root growth. A germinati...

Paper birch (Betula papyrifera Marsh) seedlings were grown in a greenhouse in either subsoil or topsoil in factorial combination with two fertilization and drought regimes to investigate how different soil environments and nutrient availability drive belowground partitioning between growth, secondary metabolism and ectomycorrhizal (EM) associations, and impact drought tolerance of paper birch. ...

drought is one of the important environmental stresses that reduce the crop growth. oxidative stress is a secondary stress due to drought and other abiotic stresses. in order to study the effect of exogenous application of hydrogen peroxide on drought tolerance of glob amaranth (gomphrena globosa l.), an experiment was conducted in greenhouse conditions. this study was designed as factorial bas...

AIM This study assessed within 4 days of suppressive test in vivo antimalarial activity of Ethanolic extract of root and stem bark of Cassia sieberiana DC against chloroquine sensitive strain of Plasmodium berghei NK65 in mice. METHODOLOGY Two sets, each of five groups of four mice per each group were used. The groups of animals were administered with 100, 200, and 300 mg extract/kg body weig...

The effects of infection by tobacco cyst nematode (Globodera tabacum solanacearum) on growth of flue-cured tobacco cultivars NC 567 (resistant) and K 326 (susceptible) were evaluated in the field in 1993 and 1994. Infection by G. t. solanacearum suppressed number of leaves, plant height, and fresh weight of leaves and feeder roots. Correlations between weekly egg densities of G. t. solanacearum...

To study drought stress on seedling dry weight, proline contents and evaluate of antioxidant enzymes activity in canola genotypes (Brassica napus l.), an experiment were evaluated at laboratory physiology, Shahed University. This experiment was carried out in factorial with CRD design with 4 replications in 2008. The first factor was including levels of dough stress, one without stress as check...

Field experiment was carried out at Ornamental Nursery, Department of Horticulture, Khyber Pakhtunkhwa (KP) Agricultural University Peshawar, during 2009 to study “the response of plane tree cuttings to different planting dates”. Three types of cuttings (hardwood cuttings, semi-hardwood cuttings, Softwood cuttings) and three dates (6 January, 21 January and 5 February) were studied. The experim...

in order to study of yield, growth index and physiological traits in spring sugar beet genotypes with delayed planting date, a field experiment was carried out in chenaran in khorasan razavi province in the east of iran in 2008 cropping season. for this experiment a complete randomized block design with 4 replications and 6 treatments was used. the experimental treatments were six improved vari...

licorice, glycyrrhiza glabra (fabaceae), is one of the herbal medicines. glycyrrhizin is the importance content through compounds exiting in licorice, which is 50 times sweeter than sucrose. glycyrrhizin used as the primary matter in pharmacy and used to remedy of many diseases, and also, used in tobacco, confectionary and beverage industries. since glycyrrhizin in the phases of growth received...
