Quantitative and qualitative analysis of phenolics and boron in stigma of transient sterile Tecoma stans L. during seedless (May-July), partially seedbearing (August-November, April) and seedbearing periods (December-March) was made. UV absorption profile of stigmatic exudates indicated the presence of simple phenolics. Total phenolics were higher in stigma during seedless period. Thin layer ch...

Grapes are important sources of phenolic compounds, which have multiple beneficial effects on human health. Scientific advances in the field genetics allowed production seedless table grape varieties, highly demanded by consumers because their nutritional value and easy consumption. In this study, total content (TPC), radical scavenging activity (RSA) anthocyanin (TAC), were determined 65 varie...

drying is one of the most important steps in raisin processing. during this step, initial moisture content decreases up to 15-17% (db) for suitable storage. achieving optimum drying conditions can affect the processing time and improve raisin quality. temperature, air velocity and pretreatment are important factors in the quality of the grape drying process. in this research, the effect of temp...

This study was conducted to examine the effects of grape maturity and processing method on the quality of juices from four French-American hybrid wine grape cultivars (Seyval, Vidal, Aurore, and Chancellor). The flavor of juices from more mature grapes (soluble solids:acidity ratio of 20 30, pH 3.45 3.60) was rated higher than the flavor of less mature grapes (soluble solids:acidity ratio of 13...

Abstract Grapevine ( Vitis vinifera L.) is the most widely cultivated fruit crop worldwide, contributing substantially to rural economies. The production cycle and productivity depend on seasonal cues can range from a strongly deciduous habit in cool‐temperate climates evergreen subtropical tropical climates. influence of different conditions dynamics perennating bud, including degree growth me...
