Water deÞcit and shade stress in weed-infested crops could alter plant growth and biochemistry and feeding and oviposition by the beet armyworm, Spodoptera exiguaHübner. Palmer amaranthpigweed,Amaranthus palmeriS.Wats.,was grownunder 25%of fullwatering(waterdeÞcit), 30% of full light (shade), or combined stress. All treatments decreased plant height andweight. Shade and combined stresses decrea...

ABSTRACT Rice is one of the main foods consumed by half world’s population. The rice crop requires plenty water, but upland cultivated in a non-flooded environment, although its productivity lower than that lowland rice. grains mostly consist starch, which synthesized from non-structural carbohydrates imported vegetative organs. long-term storage plays remarkable role maintaining supply photoas...

bermudagrass [cynodon dactylon (l.) pers.] is a perennial grass and has been long used as a medicinal herb in iranian traditional medicine to treat varied ailments. different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. g...

The potential for using readily available and cost-effective complex carbon sources such as primary sewage sludge for a range of biological processes, including the bioremediation of acid mine drainage, has been constrained by the slow rate of solubilisation and low yield of soluble products, which drive the above mentioned processes. Previous research into the hydrolysis of complex organic mat...

Dietary guidelines encourage a considerable increase in carbohydrate intake compared with the present situation in Western countries. Recent developments regarding nutritional effects of various digestible and undigestible carbohydrates call for more detailed recommendations. The "carbohydrates by difference" concept emerged 150 y ago because of the lack of specific analytical techniques and st...

Research was conducted on Aloe vera, a traditional medicinal plant, to investigate the effects of light on growth, carbon allocation, and the concentrations of organic solutes, including soluble carbohydrates and aloin. The plants were vegetatively propagated and grown under three irradiances: full sunlight, partial (30% full sunlight), and deep shade (10% full sunlight) for 12-18 months. After...

cold stress is one of the limiting factors in production of greenhouse vegetables. chemicals offer useful approach to reduce low temperature-induced damages. this study was conducted to evaluate the effect of foliar application of methyl jasmonate (meja) at concentrations of 0 (control), 50, 100, 200 µm) on electrolyte leakage (el), relative water content (rwc), soluble carbohydrates, proline, ...

the aim of the present study was to evaluate the effects of sun-drying, ensiling and addition of polyethylene glycol (peg) on deactivation of tannins in the pistachio by-products hull (pbh). the chemical composition, protein quality and phenolic compounds of fresh pistachio by-products hull, sun-dried and ensiled for either 30 or 60 days were assessed. organic matter digestibility (omd) and met...

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...
