The physiology of NaCl induced stress was studied in two prop species, cowpea and 4 cultivars of tobacco one of which (Jayashree) is salt sensitive. It was found that the growth of all the cvs of tobacco was reduced by the presence of NaCl (100 mH) in the nutrient medium. While the fresh wt per unit area of the leaves of salt-tolerant tobacco cv. I and PV-7 (Nicotiana tabacum L.) and MPS-219 (N. rustica L.) was increased' significantly, it was decreased in the salt-sensitive Jayashree. The dry wt per unit leaf area was decreased much more in I, PV-7 and J than in NPS-219. The total chlorophyll was reduced in all and more so in Jayashree. The relative turgidity % was found to decrease in the primary leaves of cowpea (Vigna unguiculata L.) in the first 6 days of treatment with 100 mM NaCl in the nutrient medium while the decrease was less significant in the first and and second trifoliate leaves, showing that there was readjustment with growth of the plant to salinity. The 14C fixation in the leaf disks of cowpea grown in NaCl was much less than in the control plants. The studies reveal that there is a general reduction in the growth of both tobacco and cowpea following NaCl treatment and this effect is due to a decrease in the total chlorophyll and a reduced rate of photosynthesis. |
