Sesbania

Although root nodules are the most common sites of N2-fixiag symbioses, some tropical legumes like Sesbania produce stem nodules ia associatioa Jp rhi bium caulinodans (55). la coatrast to root aodules, some stem aodules are photosyathetic and contain, ia the case oiPieschjnomene indica rhizobia themselves capable of photosyathesis (56). This close relatioaship of photosyathesis to fixatioa may ease the eaergy supply demand of nodules.

Effects of allelopathic compounds. To compare the sensitivity of shoot and root length to PSRFW, 25 additional compounds were tested at 2 mH as described in the previous section. Hemp sesbania was harvested at 60 h and barnyardgrass at 72 h. These times were chosen in an attempt to maintain sufficient solution volume during the experiment. Root and shoot lengths, fresh and dry total weights, and percent germination were then determined. TFW was used to determine PSRFW.
