摘　　要：为筛选适宜在广州从化区种植的香稻品种,以6个香稻品种为材料,调查各香稻品种的产量和籽粒香气(2-AP)含量。结果表明,软华优金丝产量最高,为548 kg/hm^(2),但象牙香占、青香优19香、美香占2号的产量与软华优金丝无显著差异。象牙香占籽粒2-AP含量最高,与青香优19香差异不显著,但显著高于其他品种。各品种2-AP含量高的原因在于叶片和籽粒中前体物质如脯氨酸、1-吡咯啉和1-吡咯啉-5羧酸含量保持较高水平。象牙香占、青香优19香和软华优金丝在从化种植可以同时保持较高的产量和籽粒2-AP含量,可为从化香米产业的发展提供良好的品种支持。To screen suitable fragrant rice varieties for planting in Conghua District,Guangzhou,we used six fragrant rice varieties as materials to investigate the yield and grain aroma(2-AP)content of each fragrant rice variety.The results showed that the yield of Ruanhuayoujinsi was the highest,with a yield of 548 kg/hm^(2),but there was no significant difference to Xiangyaxiangzhan,Qingliangyou 19 xiang,and Meixiangzhan 2.Xiangyaxiangzhan had the highest 2-AP content in grains,which was not significantly different from Qingxiangyou 19 xiang,but significantly higher than other varieties.The high 2-AP content of each variety was due to the high content of precursor substances such as proline,1-pyrroline,and 1-pyrroline-5 carboxylic acid content in leaves and grains.Xiangyaxiangzhan,Qingliangyou 19 xiang,and Ruanhuayoujinsi could maintain high yields and 2-AP content in grains during planting in Conghua,which could provide good variety support for the development of the fragrant rice industry in Conghua.
