Seed evaluation of harvested pastures in roads and crop fields

Abstract

The physiological and physical quality of the grass seed Sporobolus aeroides, Bouteloua curtipendula, Briza
minor, Bromus mollis, Chencrus ciliaris, Rhynchelytrum repens, Eragrostis curvula, Bouteloua gracilis,
Setaria geniculata, Leptochloa filiformis, Bothriochloa perforata y Digitaria califórnica collected in Soledad
de Graciano Sánchez, SLP in the years 2013, 2014 and 2015. The percentage of germination (PGER),
dead seed (DS), seedling dry weight (SDW), seedling height (SH), analytical purity (AP), thousand seed
weight (TSW) and volumetric weight (VW) were evaluated. The largest PGER was for Pega Ropa 2014 with
91.7%, and the minimum in Banderita 2014 with 23.2%. For DS Popotillo Plateado 2013 showed the highest
percentage (9.5%). For SDW, Carretero grass 2014 presented the highest value with 0.6266 g for 20
seedlings. For SH, Punta Blanca grass 2014 presented the highest value with 15.25 mm. For AP for the
year 2013 the Alcalino grass obtained a 100%, Plumilla 2013 presented 69.66%, in 2014 the Alcalino grass
showed 100% and Buffel the lowest with 65%. For VW the Alcalino 2015 showed the highest value with
64.32 kg hl-1. It is concluded that the evaluation of the seeds showed variability in quality.
