Interação entre plantas de festuca alta de diferentes origens, livres e infectadas por fungos endofíticos
Palavras-chave:
festuca arundinacea, Epichloë coenophiala, endófitos não tóxicos, desempenho relativo, índice de agressividade
Resumo
A festuca alta cresce em pastagens e também é cultivada em pastagens. Esta gramínea é frequentemente infetada por um fungo endofítico selvagem que produz alcaloides tóxicos para o gado. Uma estratégia para reduzir a toxicidade é intercalar a gramínea com outras espécies não afetadas, leguminosas, gramíneas e cultivares inoculadas com endófitos seguros (não tóxicos). O objetivo deste estudo foi analisar, sob corte, o crescimento vegetativo e reprodutivo de plantas de festuca alta naturalizadas infetadas com endófitos selvagens (PE+), cultivadas em mistura com: i) plantas de festuca alta naturalizadas isentas de endófitos (PE-); ii) uma cultivar livre (TE-); iii) uma cultivar infetada com o endófito não tóxico AR584 (TE+). Foram cultivadas duas plantas por vaso em condições de campo nos seguintes sete arranjos: as monoculturas PE+PE+, PE-PE-, TE-TE- e TE+TE+, e as misturas 1:1 PE+PE-; PE+TE+; PE+TE-. A experiência foi conduzida utilizando um delineamento inteiramente casualizado com oito repetições. A produção cumulativa de biomassa acima do solo foi calculada a partir de quatro cortes sucessivos de cada vez que foram registadas duas folhas novas e totalmente expandidas no perfilho principal. Após o último corte, em três repetições, a planta inteira foi colhida e fracionada em biomassa acima do solo e das raízes. Os índices de competição e agressividade foram calculados a partir dos dados de biomassa acima do solo. As restantes cinco repetições foram cultivadas para completar o seu ciclo reprodutivo. O número de panículas por planta e o número de sementes produzidas foram determinados, e o esforço reprodutivo foi calculado. Sob nossas condições, a cultivar Taita infectada com o endófito seguro foi mais competitiva em termos de produção de biomassa acima do solo do que as plantas da população selvagem infectada com o endófito. Trabalhos futuros devem considerar a análise dos alcaloides na mistura sob diferentes condições ambientais na região.
