Investigations of the effects of elevated ozone (O(3)) on the virus-plant system were conducted to inform virus pathogen management strategies better. One susceptible cultivar of tobacco (Nicotiana tabacum L. cv. Yongding) and a resistant cultivar (Nicotiana tabacum L. cv. Vam) to Potato virus Y petiole necrosis strain (PVY(N)) infection were grown in open-top chambers under ambient and elevate...

When succulent plants growing under favorable conditions of light, temperature, and moisture, are deprived of nitrogenous fertilizer their chemical composition and growth habits generally change. These responses usually include an increase in the carbohydrate content, particularly in the case of the polysaccharides, followed by a decrease in moisture content and percentage of total nitrogen, wh...

drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

The increase of atmospheric CO2 due to global climate change or horticultural practices has direct and indirect effects on food crop quality. One question that needs to be asked, is whether CO2 enrichment affects the nutritional quality of Malaysian young ginger plants. Responses of total carbohydrate, fructose, glucose, sucrose, protein, soluble amino acids and antinutrients to either ambient ...

the effect of different concentration of salicylic acid (0, 1 and 2 mmoll-1) and chitosan (0, 0.5 and 1 percent) on postharvest life and quality of selva strawberry fruit during storage at 2.5±0.5°c with 85-95% rh for 7 and 14 days was studied. decay incidence, marketability, total soluble solids, total acidity, vitamin c content and total antioxidant activity were evaluated during storage. chi...

Water shortage is one of the most important environmental stresses in Mediterranean regions. Poor seedling quality may account for the failure of oak regeneration. To determine the best seed origin of Quercus brantii, we investigated on seedlings collected from 20 mother trees in the Zagros Mountain forests 700 to 2200 m altitudes above sea level. Seedlings from different altitudes were irrig...

the present study was conducted to investigate the effects of ensiling pistachio by-product (pbp) on nutrient value, some physical and chemical parameters. fresh pbp was ensiled into a trench silo for three months and simultaneously amount of pbp was dried in front of the sun. chemical composition, buffering capacity, water holding capacity, protein fractionation according to cornell net carboh...

Climate warming increases the risk of insect defoliation in boreal forests. Losses in photosynthetically active surfaces cause reduction in net primary productivity and often compromise carbon reserves of trees. The concurrent effects of climate change and removal of foliage on root growth responses and carbohydrate dynamics are poorly understood, especially in tree seedlings. We investigated i...

The effect of NaCl and ABA on germination, sugars and enzymes of carbohydrate metabolism in sorghum embryos and endosperm was investigated. Both phytohormone and salt stress influenced different aspects at physiological and biochemical level. Germination decreased markedly under NaCl and ABA treatments. Subsequently, an influence of salt stress and ABA on total and reducing sugars along with am...
