The Effects Of Genotype And Altitude Of The Growing Location On Physical, Chemical, And Phytochemical Properties Of Strawberry, Kazi̇m Gündüz, Hakan Özbay
Turkish Journal of Agriculture and Forestry
The effects of genotype and altitude of the growing location on physical, chemical, and phytochemical properties of strawberry fruits were investigated. Eight strawberry genotypes obtained from diverse breeding programs were selected. The genotypes were grown at three altitudes: in Antakya (117 m), Urumu (443 m), and Saksak (755 m). The results indicated that genotype and growing location had a significant impact on both physico-chemical and phytochemical characteristics. Genotypes explained 36%?51% of total variance for fruit weight (FW), total soluble solids (TSS), total acidity (TA), color incidence chroma (C), hue (h°), citric acid, and total monomeric anthocyanin (TMA). Altitudes explained 23%?50% …

Turkish Journal of Agriculture and Forestry
The effect of altitude, shooting period, and tea grade on the catechins and caffeine contents of Turkish black tea was investigated. The experimental factors significantly affected all of the parameters analyzed. Epigallocatechin gallate was the major catechin of black tea (0.719-1.007 g 100 g-1 dm) followed by epigallocatechin (0.627-0.791 g 100 g-1 dm). Additionally, caffeine (1.810-2.175 g 100 g-1 dm), theaflavin (3.201-6.000 μmol g-1), and thearubigin (8.577-12.635 g 100 g-1 dm) contents were determined. Samples of tea grown at high altitude generally produced a considerably greater amount of the catechins that improve tea quality. Shooting period, which is specific to …
