Global field trials show the advantages of beta regression compared with logit transformation and quasi‐likelihood for the analysis of percentage plant disease severity

Annals of Applied Biology, EarlyView.
Disease severity in crop protection field trials is commonly assessed as a proportion represented as a percentage. Traditional statistical analysis uses transformation to logit or angle. This study compares analyses based on the beta distribution and the quasi‐likelihood method with the logit transform using a large global data set of field trials ...

Quantification of leaf stripe, Pyrenophora graminea, in barley seed by real-time PCR [PDF]

, 2005
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P.

Effects of Elevated CO2 on Bean Pod Mottle Virus Infection in Both Incompatible and Compatible Interactions With Phaseolus vulgaris L

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant viruses cause significant crop losses, a situation that could worsen due to anthropogenic activities driving global climate change, one factor of which is the increase in atmospheric CO2 concentration. This study assessed the impact of elevated CO2 concentration (eCO2, 1000 vs. 400 ppm) on two genotypes of common bean (Phaseolus vulgaris
