Abstract: In order to explore the impact of fertilizer types and fertilization methods on 2-acetyl-1-pyrroline(2AP) content in aromatic rice and its physiological characters,the widely used and popular aromatic rice cultivar,Yuxiangyouzhan was used as material in the field trials.The experiment consisted of two fertilization methods i.e.deep application of fertilizer and manual application of fertilizer,and two fertilizer types i.e.the chemical fertilizer ammonium bicarbonate+calciumsuperphosphate+potassium chloride and the compound fertilizer,the nutrient(NPK) content in each treatment with equal quality.The 2AP content in mature grain as well as the proline content,proline dehydrogenase activity,pyrroline-5-carboxylate synthetase activity,ornithine aminotransferase activity and pyrroline-5-carboxylate acid content in leaves at tillering stage,booting stage,flowering stage and maturity were measured.The results showed that fertilizer types,fertilization methods and their interaction significantly affected the 2AP content in mature grains.The manual application of ammonium bicarbonate+calciumsuperphosphate+potassium chloride had the highest 2AP content in mature grains(59.86 ng/g). And the 2AP content in mature grains was in positive correlation with pyrroline-5-carboxylate acid content in leaves at maturity significantly(r=0.957 1*).The results provide theoretical reference for the development of scented rice fertilization technology.
