In order to study the effect of calcium and humic acid foliar application on growth, yield and yield components of tomato plants as a completely randomized experimental design with four replications. These factors included humic acid in 3 levels (5, 10 and 20 ppm) and calcium in 2 levels (5 and 10 mM) spray on tomato. Results indicated that humic acid (20 ppm) and calcium (10 mM) either alone o...

Volatile compounds, physicochemical and sensory attributes of four sweet cherry cultivars (Canada giant, Ferrovia, Lapins and Skeena) grown in Northern Greece were determined. Eighteen volatile compounds were identified and semi-quantified in cherries using solid phase micro extraction in combination with gas chromatography/mass spectrometry (SPME-GC/MS). Carbonyl compounds were the most abunda...

Effects of cluster exposure and winemaking treatments on freeand potential-volatile terpenes (FVT. P VT), total soluble solids (TSS), titratable acidity (TA), phenols pH, color and potassium were studied. Canopies of Golden Muscat grape vines were manipulated by shoot positioning and basal leaf removal at fruit set to create shaded and exposed cluster conditions. Winemaking treatments included:...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

abstract antioxidant capacity and quality of fruits usually changed during storage. in the current study, the changes of antioxidant capacity and postharvest quality of two blood (pigmented) orange cultivars (‘tarocco’ and ‘morro’) and ‘thompson navel’ orange, after 60 days storage at 7ºc and 90 rh% was investigated. during fruit storage weight loss, tss, ta, tss/ta, vitamin c, total phenol, an...

this research was carried out to investigate the effect of different levels of potassium (in nutrient solution), harvest season and plant density on yield and quality of strawberry cv. selvain hydroponic system conditions. the tests were done in the greenhouse, and laboratories of horticultural science department of the university colleg of agriculture and natural resources of tehran university...
