the effect of the organic, integrated and conventional methods of kiwifruit cv. 'hayward' production on the fruit quality at its harvest time was investigated. such traits as fruit size, firmness, total soluble solids (tss), titratable acidity (ta), total chlorophyll, total carotenoids, vitamin c, total phenol, flavonoid compounds (catechin, quercetin 3-glucoside and chlorogenic acid)...

Selected physiological and biochemical parameters were monitored at the vegetative and reproductive growth stages in potted Bougainvillea plants treated with five different concentrations of TRIA. Advanced flowering, flower bud number, and blooming rate increased significantly with 0.5 and 1.0 mg/L TRIA treatments. Similarly, photosynthetic rate, pigment content, quantum yield, and stomatal con...

Strawberry fruits (cv. Benihoppe, Tochiotome, Sachinoka, and Guimeiren) were harvested and evaluated the flavor and nutritional parameters. By principal component analysis and hierarchical clustering analysis, differences were observed based on the volatile compounds composition, sugar and acid concentration, sweetness, and total soluble sugars/total organic acids of the four varieties. A total...

Background: Pineapple juice processing is an art of preservation, and the processing technologies play important role in pineapple juice quality. Therefore, this study aimed to explore the potential impacts of non-thermal processing methods on the physicochemical, bioactive, and microbiological properties of fresh pineapple juice. Methods: Extracted juices were subjected to several non-thermal...

The present investigation was undertaken to assess the effects of different doses (100, 300, and 500 mJ) low power He–Ne laser (632.8 nm) irradiation on seed germination thermodynamics attributes activities potential germinating enzymes in relation with changes metabolites. increased amylase (Amy), protease (Pro) glucosidase (Gluco) activities, a significant improvement attributes. A fast incre...

optimal nutrition of grapevine is one of the most important factors that affect the quantity, quality and time of fruit ripening. to increase the quantity and quality of ‘askari’ cultivar, a factorial experiment in a randomized complete block design with three replications was conducted at shahrekord in 2010. treatments consisted of four levels of potassium sulfate fertilizer (zero, 300, 600 an...

Under certain conditions, pulsed electric fields (PEF) can promote the accumulation of phytochemicals through a stress-mediated response in plant tissues. Likewise, electropermeabilization cell membranes also improve extraction intracellular compounds. The objective this study was to evaluate main causes driving increase carotenoids content PEF-treated carrots and impact those treatments on the...

Identifying saline soils is of great importance for protecting land resources and the sustainable development agriculture. Total soil salinity (TSS) most commonly used indicator determining salinization, but application geochemical data rarely reported. In general, there a significant relationship between TSS content soil-soluble Na, which can be estimated by difference bulk-soil Na2O its backg...

Seaweeds are rich sources of bioactive natural products, which have been considered as potential biotic agents. Ulva flexuosa Wulfen is a species of seaweed which is endemic to the Persian Gulf. In this study, the effect of different concentrations of U. flexuosa extract on  the  antioxidant activity of Washington Navel orange (Citrus sinensis L. cv. Washington Navel)...
