Effects of nitrogen application on aroma of aromatic rice and their mechanism

Taking the conventional aromatic rice, Guixiangzhan and Meixiangzhan as materials, using pot experiment, effects of different nitrogen application in different periods on aroma of aromatic rice and their mechanism were studied. The results showed that, nitrogen application aromatic rice Guixiangzhan and Meixiangzhan could increase the free proline content and 2-acetyl-1-pyrroline content in brown rice, while for Meixiangzhan, the treatment of basal and tillering fertilizer nitrogen reduced 2-acetyl-1-pyrroline content in brown rice.
