研究了天竺葵对矿质营养的需求。“艾琳”，被研究了。植物生长在含有不同量的N、P、K、Mg和Ca或缺乏S、B、Fe、Mn、Cu或Zn的溶液培养物中。描述了所列元素的缺陷症状。发现最初显示缺乏的叶片中的矿物质水平处于近似初始缺乏：N，2.40%; P，0.28%; K，0.62%; Ca，0.77%; Mg，0.14%; S，0.12%; B，18 ppm; Fe，60 ppm; Cu，5.5 ppm; Zn，6 ppm;和Mn，9 ppm。提供了其他有用的分析数据。
The mineral nutrient requirements of geranium, Pelargonium hortorum, cv. ‘Irene’, were studied. Plants were grown in solution culture containing varying quantities of N, P, K, Mg, and Ca, or deficient in S, B, Fe, Mn, Cu, or Zn. Deficiency symptoms of the elements listed are described. The mineral levels in leaves which first show deficiency were found to be at approximate incipient deficiency: N, 2.40%; P, 0.28%; K, 0.62%; Ca, 0.77%; Mg, 0.14%; S, 0.12%; B, 18 ppm; Fe, 60 ppm; Cu, 5.5 ppm; Zn, 6 ppm; and Mn, 9 ppm. Additional useful analytical data are presented.
