CASSAL, V.B. et al. Morphogenetic characteristics during establishment of two Bromus catharticus accesses. Arch. zootec. [online]. 2010, vol.59, n.226, pp.287-290. ISSN 1885-4494.

Morphogenetic characteristics of two accesses of Bromus catharticus Vahl. (Agros-tologia and Platano) were studied during the establishment period. The experiment was carried out in greenhouse at UFPEL, Animal Science Department, using pots in a completely randomized design with eight replications, from June 19^th to August 11^th , in 2006. Plants were evaluated with intervals from two to three days in a week. Length and number of the leaf blades in the main tillers were measured, with scale and marked with a colour wire. Leaf appearance rate and phyllochron did not differ significantly (p>0.05) for both accesses, however, leaf elongation rate of Platano was higher (p<0.05) than of Agrostologia access.

Keywords : Blade length; Leaf elongation rate; Tillers. Phyllochron.
