Abstract

Li, J., Percival, D., Hoyle, J., Yue, J., White, J., Head, K. and Pruski, K. 2015. Environmental effects on fruit composition of cloudberry/bakeapple (Rubus chamaemorus L.) grown in southern Labrador, Canada. Can. J. Plant Sci. 95: 1167-1175. The composition of fruit collected from three fields located near Lanse'au Clair, Red Bay and Cartwright in southern Labrador, Canada, was analyzed over the 2011 and 2012 growing seasons. Soluble solids, titratable acidity, total phenolics, total anthocyanins, chlorogenic acid, caffeic acid, quercetin-3-glucoside, cyanidin-3-glucoside and ellagic acid were determined after each harvest using standard laboratory procedures. Temperature, precipitation, wind and other environmental factors affected growth and deposition of nutrients in harvested fruit. Soluble solids content (TSS), titratable acidity (TA), total anthocyanin, chlorogenic acid, cyanidin, total phenolic compounds and total anthocyanins of cloudberry fruit were significantly (P<0.05) affected by the combina...
