Defoliation Frequency Effects on Shoots and Roots of Poa ligularis in Arid Patagonia, Argentina
Busso, Carlos Alberto; Gittins Lopez, Cecilia Gabriela; Becker, Guillermo Fernando (Sryahwa Publications, 2016)Poa ligularis is an important forage, perennial bunchgrass in Patagonian rangelands. We hypothesized that (1) root biomass in P. ligularis is not reduced by increased defoliation frequency, as carbon would be allocated ... -
Tiller hierarchy and defoliation frequency determine bud viability in the grass Poa ligularis
Busso, Carlos Alberto; Gittins Lopez, Cecilia Gabriela; Becker, Guillermo Fernando; Ghermandi, Luciana (Wiley, 2011-06-21)Bud viability after various defoliation frequency treatments was determined in the perennial bunchgrass Poa ligularis under arid field conditions from 2002 to 2005. Bud respiratory activity was examined on various stem ...
