Reed rhizomes from four habitats differing in soil nitrogen availability were collected and analysed for carbohydrate content during one year. Rhizomes collected from sediments where nitrate was the prevailing form of available nitrogen accumulated predominantly starch. On the other hand, rhizomes buried in sediments rich in ammonium contained predominantly sucrose. These observations together with the fact that ammonium stimulates the activity of enzymes involved in degradation of starch… CONTINUE READING
