BACKGROUND Sudden death syndrome (SDS) caused by the ascomycete fungus, Fusarium virguliforme, exhibits root necrosis and leaf scorch or foliar SDS. The pathogen has never been identified from the above ground diseased foliar tissues. Foliar SDS is believed to be caused by host selective toxins, including FvTox1, secreted by the fungus. This study investigated if the xylem sap of F. virguliform...

in order to study the effects of soil and foliar application of fe-eddha on some biochemical and physiological traits in safflower under two irrigation regimes an experiment was conducted in 2008 growing season in research field of faculty of agriculture, shahed university. the experimental design was a split-plot based on randomized complete blocks with four replications. mainplots consisted o...

Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein...

Relationships of foliar carbon isotope composition (δ(13)C) with foliar C, N, P, K, Ca, Mg contents and their ratios of 219 C3 species leaf samples, obtained in August in 2004 to 2007 from 82 high altitude grassland sites on the Qinghai-Tibet Plateau China, were examined. This was done with reference to the proposition that foliar δ(13)C increases with altitude and separately for the life-form ...

Plant biostimulants such as arbuscular mycorrhizal (AM) fungi and humic substances (HS) can be used as an appropriate alternative to chemical fertilizers, as regards to environmental problems of chemicals. The effects of Funneliformis mosseae as an AM fungus, HS (foliar spray and topdressing application), and chemical fertilizer (NK), separately or interacting, on biochemical responses in Menth...

growing demand for wheat grain with optimal technological parameters results in looking for the possibilities of accurately meeting the plant needs. environmental conditions in the surroundings of germinating grains can be improved by application of humic preparations. qualitative features of grain can be also changed by foliar application of potassium, which is the activator of enzymes catalys...

Leaf detachment is a common signal that triggers both the differentiation of dormant epiphyllous buds as well as the onset of foliar senescence in Kalanchoe pinnata Lam. (Pers.). The present study looked for any probable correlations among selected attributes of foliar senescence, e.g. soluble proteins, chlorophylls a and b (Chl(a+b)), and membrane stability index (MSI), and the antioxidative s...
