Using Principal Component Analysis to Assess Water Quality from the Landing Stages in Coastal Region
Principal component analysis (PCA) was used to comprehensively evaluate the relationship between physicochemical and bacteriological parameters of water on banks Wouri. At each sampling station, focused Water temperature, pH, dissolved oxygen, CO2, electrical conductivity, suspended solids, nitrates, ammonium ions, orthophosphates, color, salinity, turbidity. The consisted isolation heterotroph...
Abiotic stresses strongly affect plant growth, nutrient composition and quality of production; final crop yield can be really compromised if stress occurs in plants’ most sensitive phenological phases. The present field study was conducted to evaluate the effect biostimulants on improvement tolerance tomato plants exposed salinity. soil condition with pH- 8.7 EC- 4 dS m-1 recorded. After first ...
in the present study application of x-ray computed tomography as a nondestructive technique for estimation of some qualitative parameters of pomegranate fruit was studied. for this purpose, three local cultivars of pomegranate fruit of fars province, iran that included; rabab malas, rabab torsh and khani kazeroon were used. the x-ray ct images of pomegranate fruits were prepared using ct-scan d...
In calcareous and alkaline soils, which include most of Iran soils, iron deficiency is prevalent. The main cause of iron deficiency chlorosis is high pH of soil. Among fruit trees, peach shows high sensitivity to iron deficiency. Chelated iron fertilizers with a great ability to make iron soluble and readily absorbed by the plant are used for iron deficiency. For this purpose, an experiment bas...
abstract: edible coatings made from whey protein concentrate (wpc) and gellan gum (g) were investigated for their capacity to preserve the quality of malus domestica cv golab apples. wpc and gellan gum coatings at different concentrations plasticized with glycerol (gly) were tested. postharvest storage quality condition testes included weight loss, color and texture changes, titratable acidity ...
Melatonin has different physiological functions in plants, such as active growth regulator signal. A factorial experiment, based on randomized complete blocks design, was carried out in order to evaluate of the effect of melatonin and sodium nitroprusside (SNP) on morpho-physiological traits of cut flower Gerbera (Gerbera jamesonii cv. Malibu) under salinity stress. The first factor in this exp...
Salinity is a limiting factor in agricultural production that inflicts great damages on agricultural products. In order to decrease or stop salinity stress, numerous methods are proposed by different researchers. One of the methods to reduce the damages of salinity stress is cultivating tolerant plants to salinity. In this research, resistance of three radish cultivars to salinity stress was in...
the present study aimed to evaluate the effect of dipping time and temperature of hot water and type of packaging on qualitative traits of orlando tangelo variety of tangerine. this study was conducted as a factorial experiment in a completely randomized design with three repeats. the treatments consisted of dipping in hot water at seven water levels at 53°c and 58°c each for 1, 2 and 4 minutes...
to study the effect of salinity and organic matter on chemical composition and root morphology of pistachio cv. badami, budded on seedling root stocks, a greenhouse experiment was conducted as a factorial based on a completely randomized design with three replications. treatments consisted of four salinity (zero, 800, 1600 and 2400 mg nacl kg-1 soil) and three organic matter (zero, two and four...
