IV SIMPOSIO INTERNACIONAL DE PASTIZALES<br />

San Luis Po<strong>to</strong>sí, S.L.P. México 22 al 24 de agos<strong>to</strong> de 2007<br />

Artículos in extenso<br />

Área temática: Ecología y Conservación del Pastizal<br />

CONCLUSIONES Y RECOMENDACIONES<br />

• Existe una mayor velocidad de germinación inicial en B<strong>and</strong>erita, respec<strong>to</strong> a Buffel.<br />

• El pas<strong>to</strong> Buffel posee una mayor capacidad de germinación absoluta, comparado con<br />

B<strong>and</strong>erita.<br />

• Ecotipos de pas<strong>to</strong> B<strong>and</strong>erita con potencial mediano de producción de forraje, poseen<br />

mayor potencial de germinación inicial, respec<strong>to</strong> a ecotipos con potencial de<br />

producción de forraje al<strong>to</strong>.<br />

• Existe variabilidad para calidad de forraje en B<strong>and</strong>erita.<br />

• Se requieren estudios de dinámica de crecimien<strong>to</strong> inicial para detectar materiales<br />

agresivos al establecimien<strong>to</strong> y que posean atribu<strong>to</strong>s que incrementen el éxi<strong>to</strong> en el<br />

establecimien<strong>to</strong> de praderas de temporal de B<strong>and</strong>erita; sin embargo, existe<br />

variabilidad genética para este atribu<strong>to</strong>, en los materiales colectados.<br />
