Plots were planted on 3 June, 2004 in Langdon, ND |
|
|
|
Plots were seeded at a rate of 14 seeds/ft2 |
|
|
|
|
Statistical design was a randomized complete block with 4 replications |
|
|
Plots were evaluated for blackleg on 12 August, 2004 |
|
|
|
Blackleg Disease Severity was rated by cutting 10 stems per plot and
rating on a 0 to 5 scale, where: |
|
0= No penetration or noticeable infection of the stem |
|
|
|
1= 1/4 of the stem circumference infected; lesion superficial |
|
|
2= 1/2 of the stem circumference infected; some penetration |
|
|
3= 3/4 of the stem circumference infected; significant penetration |
|
|
4= stem completely girdled, but intact at the base; significant
penetration |
|
|
5= stem girdled at the base, constricted, dry and brittle, may be
completely severed; plant dead |
|
|
|
|
|
|
|
Disease Severity index (DSI) was calculated by: (mean disease
severity X % incidence)/5 |
|
|
