Abstract

Water deficit and salinity are the two major constraints for growth and survival of plants and effects of these environmental stresses on plant growth has been investigated for more 100 years. In order to study interactive effect of salinity and aridity on growth of two species of A.littoral is and A.logopoides an experiment in a factorial design with completely randomized arrangement and four replications was conducted under lab conditions. Treatment were combinations of four levels of water deficit (-0/3, - 5, -10 and -15 bar), four salinity levels (0, 20, 25 and 30 dSm-1) and two species of Aeluropus. Water deficit was induced by weight method based on the amount of water lost each day. For this purpose WATER POTENTIAL of the soil used was measured by pressure plate method and on the basis of weight of soil in each pot and the associated WATER POTENTIAL of a soil, the amount of water needed for each treatment was calculated. In order to keep the WATER POTENTIAL constant, daily application of water was made based on weight of each pot. Salt stress was made by addition of sodium chloride to the initial water applied. One month after stresses were imposed, two-weekly interval sampling was made and different measurement recorded. The results showed that in general both water and salt stress caused a decrease in LEAF AREA per plant, RGR, undeRGRound and aboveground biomass, plant height, root length and shoot/root length ratio. There was an interactive effect of salinity and water deficit on most of the parameters measured.
