| Abstract/Contents: | "Root cortical death (RCD) in grasses and cereals is a natural process closely associated with autolysis of nuclei. P. graminicola (Pg), a nectrotrophic parasite of grass roots, induces no vascular necrosis at 14-22 c, but does so on susceptible Kentucky bluegrass cultivars in unshaded turfs at >24 C. The association of Pg with RCD in bluegrass was studied under shaded and nonshaded conditions at 14, 24, and 29 C, using numbers of nuclei as an indicator of RCD. Anucleation rates in the cortical layer nearest the endodermis were directly proportional to temperature, and Pg colonized the stele only in roots with few cortical nuclei. Shading reduced the rate of anucleation at 29 C, had no effect at 24 C, and enhanced it at 14 C. RCD was a useful and quantitative indicator of environmental effects which influence the susceptibility of grasses to pathogenesis by Pg." |
