%X 鲜食玉米作为叶酸的重要膳食来源&#65292;其籽粒发育过程中叶酸含量的动态变化对指导采收期和品种选育具有重要意义。本研究以5个鲜食玉米品种(西星黑糯一号、泸紫黑糯一号、斯达糯44、西星红糯4号、京紫糯)为材料&#65292;测定授粉后第5天、10天、15天、20天、25天的叶酸含量并进行显著性分析。结果表明&#65292;5种鲜食玉米的叶酸含量在40.64~207.46 &#956;g/100g之间&#65292;且呈现显著阶段性差异。其中&#65292;京紫糯和斯达糯44表现突出&#65292;叶酸含量分别达到207.46 &#956;g/100g和206.32 &#956;g/100g。综合叶酸含量变化规律&#65292;西星红糯4号、泸紫黑糯一号、西星黑糯一号和京紫糯适宜在25天进行采收&#65292;斯达糯44则建议在20天进行采收。<br>Fresh corn serves as a significant dietary source of folate, and the dynamic changes in folate content during grain development are critical for optimizing harvest timing and breeding strategies. This study investigated five fresh corn varieties (Xixing Black Waxy No.1, Luzi Black Waxy No.1, Sida Waxy 44, Xixing Red Waxy No.4, and Jingzi Waxy) by measuring folate content at 5, 10, 15, 20, and 25 days after pollination (DAP) and conducting statistical significance analysis. Results revealed that folate levels ranged from 40.64 to 207.46 &#956;g/100g across the varieties, with significant stage-specific differences. Among them, Jingzi Waxy and Sida Waxy 44 stood out, with folate contents reaching 207.46 &#956;g/100g and 206.32 &#956;g/100g, respectively. Based on the change rules of folic acid content, Xixing Red Waxy No.4, Luzi Black Waxy No.1, Xixing Black Waxy No.1, and Jingzi Waxy are suitable for harvesting on the 25th day after pollination, while Sida Waxy 44 is recommended to be harvested on the 20th day.
