草莓叶尖烧，局部缺钙引起畸形的新兴叶片，诱导高相对湿度和减轻稀释的营养液或通过降低钾，镁或硝酸盐的水平，否则标准的解决方案。增加溶液中的磷酸盐含量没有影响，而补充硝酸钙到钙的充足水平以上增加了尖烧。叶片钙（%干重）在叶片出现期间暂时下降，并且在受影响的出现叶片中低于可比的健康叶片
Leaf tipburn of strawberry, a localised calcium deficiency causing malformation of emerging leaves, was induced by high relative humidity and alleviated by diluting the nutrient solution or by reducing the level of potassium, magnesium or nitrate in otherwise standard solutions. Increasing the phosphate content of the solution had no effect, while supplementing the calcium nitrate to above sufficiency levels of calcium increased tipburn. Leaf calcium (% dry weight) decreased temporarily during leaf emergence and was lower in affected emerging leaves than in comparable healthy ones
