栽培在潮湿地区的大麦,其籽粒常受雨水淋洗而退色,特别在成熟后期多雨的情况下更是如此。如果因雨延迟了收获,籽粒受雨淋洗可能更为严重。雨水淋洗而退色的大麦,一般不适于制作麦芽和啤酒工业。用雨水淋洗过的大麦制作麦芽时,可能籽粒有一个较长的休眠期,其浸种速度难以控制。发芽不一致不健壮还会造成麦芽产量的降低(Daniel,1977)。

Barley, cultivated in wet areas, often has its grains washed out by rain and fades, especially during the late rainy season. If the harvest is delayed due to rain, the seeds may be more exposed to rain. Barley, which has been washed away by rain and faded, is generally not suitable for the malt and beer industries. Barley rinsed with rain water may have a longer dormancy period when it is made into malt and its soaking rate is difficult to control. Inconsistent sprouting can also result in lower malt production (Daniel, 1977).
