Nematode Diversity of Native Species of Vitis in California

From 1990 through 1992, nematodes were extracted from soil samples taken from the rhizosphere of native species of grapes from four areas of northern California and two areas of southern California. For comparison, samples from domestic grapes as well as a putative hybrid of Vitis califarnica and V. vinifera were also taken. Rhizosoil from California native grapevine contained many more species...
