Sobre IBD

Um estudo ecológico das ervas daninhas da cultura do trigo em Chamkani, distrito de Peshawar, foi realizado para avaliar a composição florística e as suas características ecológicas durante 2013-2014. Ele continha 58 espécies de ervas daninhas de 21 famílias. Com base no número de espécies, Asteraceae (10 spp) e Poaceae (7 spp) foram as famílias principais. Algumas outras famílias, como Brassicaceae e Fabaceae (cada uma com 5 spp), foram as seguintes em termos de riqueza de espécies. As famílias restantes tinham 4 espécies ou mais. A forma de vida estava restrita a terófitas (47 spp, 81,03%), seguidas por teófitas (7 spp, 12,06%) e hemicriptófitas (4 spp, 6,8%). O espectro do tamanho das folhas revelou que havia 37,9% (22 espécies) de nanofilas, 29,31% (17 espécies) de microfilas, 20,68% (12 espécies) de leptófilas e 12,06% (7 espécies) de mesófilas. O resultado mostrou uma menor diversidade de ervas daninhas em comparação com a literatura citada, devido às modernas instalações agrícolas, à agricultura e à proximidade de herbicidas. No entanto, algumas das ervas daninhas tornaram-se tolerantes e crescem abundantemente.
