让三个小麦品种在三个水平的氮素条件下生长,取下颖果和颖片,用同一标准的苯酚测定其颜色反应。结果发现不同氮素水平下生长出的材料间反应有差异,表明苯酚测定可能受到母体环境条件的影响。 Three wheat cultivars were grown under three levels of nitrogen, the caryopsis and glume were removed, and the color reaction was measured using the same standard of phenol. The results showed that there were differences in the reaction of materials grown at different nitrogen levels, indicating that phenol determination may be affected by the maternal environmental conditions.
