国家标准和国际规程规定:小麦种子水分测定的试样必须磨碎。实际工作中有时会遇到测试样品数量较多或室内空气相对湿度高于70%等情况。若直接采用整粒烘干,便可克服大批量试样磨碎的繁琐以及高湿对测定结果的影响。为此,我们对整粒烘干法测定小麦种子水分进行了初步研究。1 材料和方法1·1 供试材料试材选用本校育种教研室1993年收获的4种不同皮色与粒质的小麦种 National standards and international regulations: wheat seed moisture determination of the sample must be ground. Actual work sometimes encounter more test samples or indoor air relative humidity higher than 70% and so on. If the direct use of whole grain drying, you can overcome the cumbersome high-quality sample grinding and high humidity on the determination of the impact. To this end, we conducted a preliminary study on the moisture determination of wheat seeds by the whole-grain drying method. 1 Materials and methods 1.1 The test material selected test materials used in the breeding school in 1993 four different skin color and grain of wheat
