Defoliation frequency affects morphophysiological traits in the bunchgrass Poa ligularis
Phyton, 2010 Poa ligularis es una forrajera importante en los pastizales de la Patagonia. Las poblaciones de esta graminea cespitosa perenne han sido afectadas severamente por el sobrepastoreo. En este estudio proponemos que incrementos en la frecuencia de defoliacion reduciran (1) la produccion de materia seca aerea y subterranea, (2) la supervivencia de raices, y

Bromus-Poaresponse to defoliation intensity and frequency under three soil moisture levels [PDF]
Canadian Journal of Plant Science, 2002 Smooth brome (Bromus inermis Leyss.) and Kentucky bluegrass (Poa pratensis L.) are important herbage for livestock and wildlife in Aspen-Boreal ecosystems in central Alberta, but there is paucity of information on the relationship between soil moisture and defoliation regimes on herbage production in these ecosystems.

Impact of defoliation intensity and frequency on N uptake and mobilization in Lolium perenne [PDF]
Journal of Experimental Botany, 2006 The aim of the study was to evaluate the impact of defoliation intensity, defoliation frequency, and interactions with N supply on N uptake, N mobilization from and N allocation to roots, adult leaves, and growing leaves. Plants of Lolium perenne were grown under two contrasted N regimes.
