Abstract
The present study was conducted to investigate the effects of Sodium Chloride (NaCl) 60 milli Molar (mM) and 80mM on inoculated and uninoculated plants of two cultivars (Williams-82 and its hypernodulating mutant NODI-3) of soybean [Glycine max (L.) Merr.]. The study comprised two sets of experiments. Experiment I was aimed at investigating the changes in Indole Acetic Acid (IAA) as auto regulatory factor for root nodulation and its response under NaCl stress. In this experiment, the changing level of IAA was monitored at 48 h after inoculation, in leaves of potted plants of soybean cultivars, grown under controlled conditions. A decrease in IAA content was found in both the cultivars with salt treatment in inoculated plants. The uninoculated plants showed an increase in IAA content with salt stress. The level of IAA and sugar content was also measured in phloem sap at 0 hour (h), 48 h --- the critical stage of nodule development, and at 192 h after inoculation, that is, at nodule initiation. Sugar content in phloem sap varied in both the varieties. Williams-82 showed more sugar contents in phloem sap while NODI-3 showed more accumulation of sugar in leaves. NaCI treatment reduced the sugar as well as IAA content in phloem sap in Williams-82, while, there was an increase in NODI-3. Experiment 2 was designed to study the effect of inoculation and NaCl (60mM and 80mM) treatment on the root nodulation, yield performance and nutritive quality of soybean. NODI-3 showed more accumulation of sugar in leaves, greater number of nodules plant -1 . Williams-82 exhibited higher protein content in leaves
