Studies on the vegetative growth requirements of Psathyrella atroumbonata, pegler, an edible mushroom in Nigeria

  Growth requirements of Psathyrella atroumbonata Pegler, a Nigeria edible mushroom were studied. Glucose was the best carbon source. This was followed by maltose, starch and manitol in that order. The least growth was observed in lactose and cellulose. Yeast extract which is organic nitrogen proved to be the best nitrogen source. P. atroumbonata utilizes organic nitrogen better than...

Changes in fatty acid composition of polar lipids associated with growth and senescence in leaves of Catharanthus roseus

  Polar lipids are important membrane components of plant cells. They are known to affect certain membrane properties like permeability, fluidity and active transport. In the present study, individual leaf buds were tagged on the day of appearance and sampling began 7 days later. Additional samples were taken at 7 days intervals until leaf abscission occurred about 77 days after tagging. The experiments were...
