Uromyces phaseoli, the causal agent of bean rust, suppressed shoot and root growth of three bean cultivars, reducing root weight more than shoot weight. The greatest suppression of root weight was on the cultivar that appeared most susceptible by visual ratings of shoot symptoms. Meloidogyne incognita suppressed shoot and root growth of all test cultivars; root weight reductions differed among ...

The use of metal-accumulating plants to clean the contaminated soil with toxic metals is the most rapidly developing component of phytoremediation as an environmentally friendly technology. Overcoming harsh soil conditions and accelerating the recovery of degraded soils remain a worldwide restoration challenge. This study evaluated the effect of different concentrations of Pb, Zn, Cu and Fe on ...

Genetic modification of shoot and root morphology has potential to improve water and nutrient uptake of wheat crops in rainfed environments. Near-isogenic lines (NILs) varying for a tillering inhibition (tin) gene and representing multiple genetic backgrounds were phenotyped in contrasting, controlled environments for shoot and root growth. Leaf area, shoot and root biomass were similar until t...

a hydroponic experiment was conducted to evaluate the effects of salt stress on safflower genotypes under greenhouse conditions. the experiment was arranged as a factorial one based upon a completely randomized design with three replications. five safflower genotypes (arak2811, nebraska10, sod25, ca116, and ca128), and four salinity treatments (0, 0.3, 0.5, and 0.7 percent of nacl) were employe...

BACKGROUND AND AIMS This study analysed the differences in nitrogen (N), non-structural carbohydrates (NSC) and biomass allocation to the roots and shoots of 18 species of Mediterranean dwarf shrubs with different shoot-rooting and resprouting abilities. Root N and NSC concentrations of strict root-sprouters and species resprouting from the base of the stems were also compared. METHODS Solubl...

abstract in this study, interaction between amf (g. mosseae and glomus spp., respectively indigenous and non-indigenous of hm-contaminated areas) with cd-resistant pgprs (bacillus mycoides and micrococcus roseus, indigenous of contaminated areas) on the growth, cd and nutrient uptake of maize plant (zea mays l.) in cd polluted soil were investigated. with increasing levels of cd, shoot and root...

To develop an alternative method for production of sarsasapogenin by plant tissue culture technique and its quantification in Asparagus racemosus and its in vitro cultures using HPTLC. Murashige and Skoog’s (MS) basal medium supplemented with various growth regulators was used for development of shoot and root calli while, hormone free MS medium was used for development of Agrobacterium tumefac...

to investigate the physiological traits of corn in terms of lead contamination with iron spray, research factorial completely randomized design with three replications was conducted in the greenhouse. the treatments consisted four levels of lead (zero, 100, 200 and 400 mg kg-1 of soil), two hybrids of maize (sc260 and sc704) and four foliar applications of iron sulfate (0, 0.2, 0.4 and 6%). lea...

Effects of humic acid on some vegetative characteristics and mineral concentrations of Mexican lime were investigated under different salinity concentrations. Four doses of humic acid (0, 1500, 3000 and 4000 mg/kg soil) and four salinity levels (1500, 2500, 3500 and 4500 µmos) were applied on Mexican lime seedlings. Experiment was conducted as a factorial arrangement based on a completely rando...
