Seed performance variables in five wild Poaceae species in La Siberia, Chapingo, Estado de Mexico
The objective of the study was to evaluate the variables of seed yield in situ in Bouteloua gracilis, Bouteloua hirsuta, Bouteloua curtipendula, Mulhenbergia rigida and Schizachyrium scoparium in La Siberia, Chapingo, Mexico. The study was carried out on wild plants in which it is applied, total stems per plant-1, number of branches plant-1, number of branches-1, number and quantity of seed-1, stem-1 and plant- 1 to later evaluate the filling percentage and viability. Data were analyzed with GLM of SAS in Completely Random Blocks design and Tukey's test (α = 0.05). There was no grass species that exceeded 25 flower stems per plant (P<0.001). B. gracilis showed a lower number of inflorescences per plant compared to B. hirsuta (P<0.001), however, with a higher number of branches (P <0.001). Seed production per plant (mg) was higher in M. rigida (P <0.001; 12902), followed by B. curtipendula (2246) and S. scoparium (1465). In physical quality of seed B. curtipendula presented a higher percentage of filling (P<0.001; 17%) and S. scoparium greater viability (P<0.001; 78%) and weight of 1000 seeds (P<0.001; 1.52 mg). In La Siberia, B. curtipendula and S. scoparium were identified as potential grasses to collect seed and then be used for reconversion or rehabilitation
