Botanical Origin and Chemical Composition of Brazilian Propolis

Journal of Agricultural and Food Chemistry, 2002
Brazilian propolis has been classified into 12 groups based on physicochemical characteristics: five in the southern Brazil group (group 3), one in the southeastern Brazil group (group 12), and six in the northeastern Brazil group (group 6). The plant origins of these groups were investigated using reversed-phase high-performance thin-layer ...

I. Pasture production and botanical composition

New Zealand Journal of Crop and Horticultural Science, 1976
Effects of superphosphate, lime, and stocking rate on pasture production were studied over a 5‐year period on a central yellow‐grey earth on the Wairarapa Plains at the Masterton Field Research Area. A high annual rate of superphosphate (500 kg/ha) did not increase pasture production above that obtained from a low annual rate (125 ...
