Abstract/Contents: | "Bentgrass, Agrostis palustris, cv. Penncross seedlings were inoculated with 0, 25, 50, 100, 200, or 400 Belonolamius longicaudatus/500 cm3 soil and grown at three nitrogen levels for 3.5 months. The soil was a mixture (1:1) of Norfolk sandy loam and 65-mesh (230 μm) sand. Seedlings were inoculated by pouring 40 ml of water with tile desired number of nematodes in holes that were punched with a template. Nitrogen solutions were applied once every 2 wk at rates that totaled 454, 908, or 1,816 g N/93 m2 at the end of the experiment. The leaves were cut once a month and weighed; the roots were collected and weighed at the end of the experiment. At the low N rate, total leaf weights were not affected by the different number of nematodes, but leaf weights of plants inoculated with up to 200 nematodes/500 cm3 increased at the higher rates of N. Leaf weights did not increase with more N when plants were inoculated with 400 nematodes. Root weights were lower with all nematode levels. Leaf-to-root ratios of plants inoculated with up to 200 nematodes/500 cm3 soil were 1.5 and 2.7 times as great with 908 and 1,816 g of N, respectively, than with 454 g of N. Nematodes per gram of root were greatest with 25 and 50 nematodes/500 cm3 soil and the high N rate. The higher N rates increased the stress potential of bentgrass by increasing the leaf-to-root ratios." |
