In order to investigate the effects of sowing dates on 2-Acetyl-1-Pyrroline content and quality and yield, to confirm the appropriate sowing date of early season aromatic rice in South China double-cropping region, a field experiment was carried out using Guixiangzhan and Nongxiang 18 cultivars to determine an appropriate sowing date for early season aromatic rice to study the effects of different sowing dates on aroma (2-AP), quality and yield.The results showed:Aromatic rice sown on 10 March achieved the highest 2-AP content.The 2-AP content of Guixiangzhan and Nongxiang 18 were up to 24.35, 11.67 ng/g respecticely.There was a significant negative correlation between 2-AP content and sunshine hours.Treatments having higher 2-AP content also had a higher free proline content, higher proline dehydrogenase activities in grain.Delay sowing properly increased the milled rice rate, while it reduced the cooking and eating quality.Guixiangzhan and Nongxiang 18 sown on 5 March achieved the highest grain yield, the yield of Guixiangzhan and Nongxiang 18 were up to 6.57, 6.77 t/ha respecticely.Delay sowing reduced yield of aromatic rice in different degrees.The yield of Guixinagzhan decreased 7.87%-18.27%, while the yield of Nongxiang 18 decreased 3.45%-24.14%.In this field condition, aromatic rice sown on 5 March achieved the highest yield, sown on 10 March achieved the highest 2-AP content.Hence, the appropriateearly season sowing date for aromatic rice was between 5 March and 10 March.
