| Abstract: | The influence of nematodes on nodulation of soybean varied according to their modes of parasitism. In the greenhouse, nodule formation was stimulated by the endoparasites, Meloidogyne hapla and Pratylenchus penetrans, but was inhibited slightly by the ectoparasite, Belonolaimus longicaudatus. In an experiment under controlled conditions in a phytotron, Heterodera glycines severely inhibited nodule formation, whereas plants inoculated with B. longicaudatus and P. penetrans had more nodules per g root than nematode-free plants. Nitrogen-fixing capacity, however, was inhibited by all three nematode species. Different light sources used in the phytotron experiment also influenced growth and nodulation of soybean. A fluorescent plus incandescent light regime resulted in plants with the greatest shoot weight, pod number, and nodules per g root. Plants grown under Lucalox lamps had excessive stem elongation. |
