甜玉米种子与普通杂交玉米不同,淀粉含量少,籽粒皱瘪,百粒重在10～15g之间。种子活力弱,其发芽率、出苗比普通的杂交玉米困难,难以达到苗全、苗匀、苗壮。如按普通的杂交玉米种子做发芽试验,较难真实的测定种子的发芽率。笔者通过多次试验,采用沙床做发芽试验,能真实的测定其发芽率,并与田间发芽率较为接近。 Sweet corn seeds and common hybrid corn is different, less starch content, grain wrinkled, 100 weight in between 10 ~ 15g. Seed vitality is weak, the germination rate, emergence of more difficult than the average hybrid corn, it is difficult to achieve Miao, Miao uniform, Miao Zhuang. Such as ordinary hybrid corn seed germination test, the more difficult to determine the true seed germination rate. The author through many tests, the use of sand bed to do germination test, the true determination of its germination rate, and germination rate with the field closer.
