摘要/Abstract

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/hm²，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。

关键词: 香稻, 2-AP, 产量, 品种

Abstract:

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/hm², 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.

Key words: fragrant rice, 2-AP, yield, variety
