- The results showed that leaf nitrogen accumulation was exponentially related to leaf SPAD values and linearly related to canopy spectral reflectance. 结果表明，小麦抽穗后叶片氮积累量也叶片SPAD值、冠层反射光谱分别呈显著的指数和线性相关；
- These results indicate that leaf SPAD values and canopy spectral reflectance are good indicators of quality formation dynamics in wheat grains. 因此，叶片SPAD值和比值指数可以用来预测单位土地面积上小麦籽粒生长过程中蛋白质和淀粉的积累动态。
- Forage canopy spectral reflectance measurements (350nm to 2500 nm) were made weekly using ASD Fieldspec in eight random spots in each of the three pastures. 试验选择3个草场,每个草场随机选取8个观测点,每周用ASD Fieldspec收集饲草的冠层反射率的数据(波段从350nm到2500nm)。
- The research was conducted to determine the relationships between post-heading leaf SPAD values, canopy spectral reflectance, and protein and starch accumulation dynamics in grains of wheat. 摘要研究了不同土壤水氮条件下小麦抽穗后叶片氮素状况和籽粒蛋白质及淀粉积累动态与叶片SPAD值、冠层光谱反射特征的关系。
