Penicillium bilaii inoculation increases root-hair production in field pea

Gulden, R. H.

Under three levels of phosphorus availability, inoculation of pea plants with Penicillium bilaii in growth pouches had no effect on root length ( excluding root hairs), mean root diameter, root-hair diameter, P accumulation or shoot growth. However, inoculation with P. bilaii resulted in 22% increase in the proportion of root containing root hairs and a 33% increase in the mean root-hair length.
