In the present experiment the effect of biofertilizers(non-application of biofertilizers, biosuperphosphate bacteria, biosulfur bacteria, rhizobium bacterium, and mycorrhizal fungus) and foliar application of salicylic acid (non-application, consumption of half and a millimolar)on biochemical chractristics and seed elements in two chickpea cultivars (Bivanij and Azad)was cond...
The mechanisms regulating the secretion of proteoglycans and collagens in chondrocytes, in particular those operating at the level of the rough endoplasmic reticulum (RER), are largely unknown. To examine these mechanisms, I studied the effects of acute ascorbate treatment on the secretion of two collagen types (types II and IX) and two proteoglycan types (PG-H and PG-Lb, the major keratan sulp...
This study was conducted to investigate the effect of formic and sulphuric acids on chemical composition, dry matter (DM) and crude protein (CP) degradability of alfalfa silage and its effect on early lactating Holstein cow as three trials. In the first trial, chopped alfalfa (22 and 33% DM) was ensiled with three levels of formic acid (0.0, 15 and 20 ml/kg DM) and two levels of sulphuric acid ...

The aim of this study was to investigate the effect of salicylic acid treatment on the expression pattern of two genes (aox2 and pal2) involved in the production of ant...
This experiment was conducted on rose cut flowers, Red Naomy cultivar, with the length of 35 cm, for 18 hours as a short-term treatment in a factorial based on completely randomized design with five treatments including sucrose + 8-Hydroxyquinoline sulfate, salicylic acid + sucrose + 8-Hydroxyquinoline sulfate, ascorbic acid + sucrose + 8-Hydroxyquinoline sulfate, Salicylic acid + ascorbic acid...
this experiment was conducted to evaluate and compare antibiotic, organic acid, probiotic and prebiotic effects on performance, egg quality and blood metabolites in commercial laying hens. the experiment was a completely randomized design with 160 laying hens strain hy line (w-36) from 32 to 42 weeks of age with 5 treatments and 4 replicates of 8 hens each. the experimental treatments consisted...
to day, the activated carbon is being used to treat the industrial and domestic wastewaters. the suitability of activated carbon for treatment of industrial wastewaters can be quickly predicted by consideration of wastewater characteristics. the results of this paper represent a first step in determining suitability of activated carbon for treatment of wastewaters or effluent of treatment plant...
effect of foliar spraying by humic acid on mineral leaf composition, yield and fruit quality of apple (malus domestica l. cv. ‘granny smith’) was studied. an experiment based on randomized complete design was conducted in khorramdare city of zanjan province. spraying of humic acid was conducted in four levels 0, 5, 10 and 15 mg/l on eight year-old ‘granny smith’ apples grafted on mm106 rootstoc...
