Chlorophytum borivilianum Sant. and Fernand (Safed musli) plants were raised in fertile soil in earthen pots and subjected to various durations of water deficit and waterlogging (5 and 10 days). The analysis of macroelement in the leaf tissue revealed that water deficit caused a decline in levels of phosphorus and potassium while there was accumulation of calcium, magnesium and sulphur. In the leaf tissue of waterlogged plants reduction in phosphorus and potassium content was noticeable while the levels of calcium, magnesium and sulphur were increased. Potassium and sulphur contents were found to be reduced in the tuber tissue by both water deficit as well as waterlogging treatments. An increase in phosphorus and magnesium content was noticed in water deficit stressed tuber tissue while similar trend was noticed in case of magnesium under waterlogging stress. The micronutrient composition was also altered due to both kinds of stresses. The contents of iron, zinc and manganese in the leaf tissue were increased by both stresses. Leaf copper content was reduced due to water deficit and increased due to waterlogging stress. An increase in iron content was observed in tuber tissue under both kinds of stresses. Prolonged waterlogging (10 days) affected the level of P, Ca, Zn and Mn in the tuber tissue. Possible implications of the above alterations in mineral status have been discussed.
