Abstract
Experiment in water culture was conducted to evaluate the calcium deficiency symptoms and their cause inSolanum tuberosum L. var. Chandramukhi. Meristematic regions at stem and roots were severely affected and ultimately ceased to grow. Plants remained stunted with few and smaller tubers. Reducing sugar, non-reducing sugar and starch accumulated more in the leaves and stems and less in roots and tubers of calcium deficient plants. Deficiency caused decrease in protein nitrogen, RNA, DNA and increase in soluble nitrogen in all the plant parts. Potassium, phosphorus, calcium and sodium contents were lower and magnesium content higher in the deficient plant, than that of the healthy ones. Morphological symptoms of calcium deficiency can be established by ionic balance and accumulation of oxalic acid in potato plants.
