The Effect of Speckled Leaf Blotch on Apical Development and Yield in Winter Wheat in New Zealand

W. J. THOMSON; R. E. GAUNT Annals of Botany 1986. doi:10.1093/oxfordjournals.aob.a087186

Other claims from this paper (10)

Intervention effect Speckled leaf blotch reduced winter wheat yield by 18 per cent.
Intervention effect Disease reduced grain number per ear in wheat.
Intervention effect Disease reduced grain weight in wheat.
Intervention effect Disease reduced wheat floret primordium number per ear, especially florets per spikelet.
Mechanism The authors suggest reduced assimilate supply affected floret primordium production.
Mechanism Disease effects on yield arose from development before and after anthesis, according to the authors.
Association Disease effects on wheat yield were not necessarily tied to peak severity timing.
Intervention effect Plots exposed only to the early disease phase had significantly reduced yield.
Observation Later yield components showed some evidence of compensation for early reductions in yield potential.
Recommendation The authors recommend disease control that accounts for early effects on yield potential.
