| Abstract/Contents: | "Paratylenchus projectus Jenkins 1956 was originally discovered associated with a decline of pasture grasses. Tobacco had been abandoned as a crop in this field owing to low yields. Tests were conducted to study the host-parasite relationships of P. projectus with tobacco variety Catterton and the tall fescue variety Kentucky 31. General effects on tobacco of 1000, 5000, and 10,000 nematodes used as inoculum were a stunting of top growth and shortening of internodes. Characteristic large, lateral roots were lacking on inoculated plants. Root proliferation was marked, causing an increase in dry weight of roots. Stunting and increased root weight also resulted following similar inoculations on tall fescue. In addition, tillering was increased. Upon microscopic examination no visible evidence of feeding was observed on the roots of either host. Small initial populations increased at a more rapid rate than larger ones." |
