Canola seed as affected by swathing time

Non-Peer ReviewedYield, weight, protein content (oil-free meal) and oil content of canola seed increased as seeds developed. Maximum values were obtained between 45-49 days after flowering, when seed moisture was 29-38%. Fatty acid composition of canola seed oil changed during seed development. The proportion of oleic (C18:1) and linolenic (C18:3) acids increased, while that of most other fatty acids decreased, as seeds developed, while Eicosenoic (C20:1) and erucic (C22:1) acids did not show a clear trend. Fatty-acids tended to stabilize by the 49th day after flowering. Early seeding resulted in higher seed yield, larger seeds, lower seed protein content and higher seed oil content, when compared to late seeding

Whole genome analysis of a schistosomiasis-transmitting freshwater snail

Biomphalaria snails are instrumental in transmission of the human blood fluke Schistosoma mansoni. With the World Health Organization's goal to eliminate schistosomiasis as a global health problem by 2025, there is now renewed emphasis on snail control. Here, we characterize the genome of Biomphalaria glabrata, a lophotrochozoan protostome, and provide timely and important information on snail biology. We describe aspects of phero-perception, stress responses, immune function and regulation of gene expression that support the persistence of B. glabrata in the field and may define this species as a suitable snail host for S. mansoni. We identify several potential targets for developing novel control measures aimed at reducing snail-mediated transmission of schistosomiasis

The effect of climate on the yield and growth of canola in western Canada

Non-Peer ReviewedThe effect of temperature and precipitation on the yield and quality of Tobin canola has been determined by a statistical method known as regression analyses. The equations obtained from this analyses were used to show how an increase in maximum temperature in the growing season reduced yield, increased protein, decreased oil content and decreased time to maturity. The equations, also, showed that increased rainfall increased yield, decreased protein, and increased time to maturity. Lower minimum temperatures were associated with higher chlorophyll content of seed. The information could be used by farmers and researchers as an index of suitability of either Polish (Brassica rapa L.) or Argentine (Brassica napus L.) cultivars for production areas in the Province
