Development of Molybdenum Deficiency Symptoms in Certain Crop Plants1
- Nobel K. Peterson and
- E. R. Purvis2
Molybdenum deficiency symptoms in six important crop plants were developed, described, and photographed. Deficiency symptoms were developed in the first generation of broccoli, cauliflower, and tobacco; in the second generation of corn, cotton and soybeans.
With large seeded crops it was necessary to develop seed low in molybdenum before severe deficiency symptoms could be produced. In the case of corn and cotton, germination of the molybdenum-deficient seed was at a slower and lower rate than for seed adequately supplied with the element. First generation cotton plants which received nutrient solution purified of molybdenum developed abnormal bolls.
Molybdenum deficiency symptoms were developed in plants grown in a pyrex glass cullet-wool mixture, pyrex glass sand, quartz sand, and aerated nutrient solution. The macronutrient stock solutions were purified of molybdenum by copper sulfide coprecipitation technique.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
