Summary
An investigation was carried out in order to study the effect of salts namely NaC1 and Na2SO4 on the rate of translocation of photosynthates in pigeonpea, at the pod filling stage. At the concentration of 10 EC NaC1 only 17% of the14C assimilates are translocated from the source leaf to the other parts of the plant. Out of this pods receive about 8%. On the other hand even at a concentration of 15 EC Na2SO4 about 30% of the total14C assimilates get translocated and out of this pods receive about 12%. From this it may be concluded that under salt-stress conditions the rate of translocation of photosynthates is adversely affected and between the two salts, NaC1 was discovered to have a marked inhibitory effect.
