A significant problem encountered in Chinese chives (Allium tuberosum) grown in greenhouses is the reduction in the yield and quality due to symptoms of withered leaf tips. Withered leaf tips of three Chinese chive cultivars were nondestructively analyzed by microbeam synchrotron radiation X-ray fluorescence (μ-SR-XRF) imaging. Dead, wilting, and healthy parts of the leaves exhibited significant variations in the mineral composition. The Ca/K X-ray intensity ratios were significantly increased with the degree of withering.
在中国温室种植的韭菜中，一个严重的问题是由于枯萎叶尖的症状导致产量和质量下降。利用微束同步辐射 X 射线荧光（μ-SR-XRF）成像技术对三个韭菜品种的枯萎叶尖进行了无损分析。死亡、萎蔫和健康叶片部分的矿物质组成存在显著差异。随着枯萎程度的增加，Ca/K X 射线强度比显著增加。
