为确定最佳适收期，对国内第一个鲜食专用玉米津鲜一号的嫩籽粒营养进行动态测定，发现：籽粒含水量、水解氨基酸、果糖、ＶＥ的含量随灌浆进程而减少；游离氨基酸、葡萄糖、蔗糖及总糖亦基本上随灌浆进程而减少，但在第１８天有一个回升小高峰；水溶性多糖、ＶＣ的含量基本上呈两头低中间高的抛物线状；粗纤维的含量随灌浆进程而增加，其中第２１天后增幅较大。根据籽粒营养动态，授粉后第１８天品质最佳，并拟定以此为适收期。
In order to determine the best harvesting period, the dynamic changes of fresh kernel nutrition of the first fresh corn-only corn variety Xian-1 were studied. The results showed that: the content of water content, hydrolyzed amino acids, fructose and VE decreased with the filling process; Amino acids, glucose, sucrose and total sugar also decreased with the grain filling process basically, but there was a small peak of rebound on the 18th day. The content of water-soluble polysaccharides and VC was basically parabolic with two low middle and high; the content of crude fiber With the process of filling increased, the increase after 21 days was larger. According to the dynamic of grain nutrition, the best quality was obtained on the 18th day after pollination, and it was formulated as the harvesting period.
