| Abstract/Contents: | In Lemtal Italian and S 24 perennial ryegrass (Lolium multiflorum and L. perenne, respectively) 2 ryegrass mosaic virus isolates suppressed the amount of crown rust emerging on leaves inoculated with P. coronata urediospores by up to 75% compared with the amount on virus-free plants. Severity of rust infection on barley yellow dwarf virus infected plants generally did not differ significantly from that on virus-free plants. When both RMV and BYDV were present, rust was restricted in Lemtal plants to a level intermediate between those occurring on plants infected by either virus alone and in S 24 plants to a level below that obtained with either virus alone. The mean water soluble carbohydrate (WSC) content of Lemtal plants was reduced )20% by RMV but was not significantly altered by BYDV. In S 24 plants the WSC content was increased by 10% by RMV and by 60% by BYDV. Rust reduced the WSC content of healthy and virus-infected plants, the reduction being positively correlated with the level of rust on the sampled leaves. In plants of Lemtal, but not of S 24, the degree of rust infection was positively correlated with WSC content of leaves from rust-free control plants. |
