内容記述タイプ Abstract
内容記述 World sugarcane production is increasing rapidly as a biofuel. In some areas in Brazil, sugarcane has been grown continually over very long periods without N fertiliser inputs. Therefore, the occurrence of N fixation has been suspected. However, quantitative studies seeking to identify the N2 fixation sites in the plant and to record the translocation of fixed N around the plant have not yet established. A 15N2 gas tracer experiment was conducted using young sugarcane plants to investigate the sites of N2 fixation and also to explore the possibility of translocation of the fixed N among the plant’s major organs. Young sugarcane plants (Saccharum officinarum L.) about 40 cm high and some 14 days after sprouting from a stem cutting were exposed to 15N2 labeled air in a 500 mL plastic cylinder for 7 days. Following the 7-day 15N2 feeding, some plants were potted and grown on in normal air for a further chase period. The incorporation of 15N into the shoot, roots, and stem cutting was analysed at day-3, and day-7 of the labeling period and at day-14, and day-21 during the chase period. After 3 days of 15N2 feeding, the % of N derived from the 15N labeled air in the shoot, roots and stem cutting were 0.027%, 2.22 % and 0.271 %, respectively. The roots showed the highest N fixing activity followed by the stem cutting, while the incorporation of 15N into the shoot was very low. After 21 days about a half of the N originating in the stem cutting had been transported to the shoot and the roots. However, the 15N fixed either in the roots or in the stem cutting remained in the original parts and was not appreciably transported to the shoot.
