Aspectos Fisiológicos Do Eucalipto Em Convivência Com Três Espécies De Plantas Daninhas

Abstract: As espécies daninhas Commelinea bengalensis (trapoeraba), Ipomoeia grandifolia (corda-de-viola) e Urochloa brizantha (braquiária) são comumente encontradas em competição com a cultura do eucalipto, sendo de difícil manejo com a utilização única de um mesmo herbicida. A avaliação da agressividade dessas espécies, por meio de variáveis fisiológicas medidas na cultura, pode ser útil no estabelecimento de estratégias de controle alternativas à aplicação de herbicidas. Deste modo, este trabalho foi proposto com o o… Show more

“…Water use efficiency (WUE) relates the amount of carbon the plant fixes per unit of water it loses Jaimez et al (2005). Thus, greater efficiency in water use indicates that the plant can produce more dry matter per gram of water transpired Faustino et al (2017). In general, the Gs values (Table 2) presented by AMF-inoculated coffee plants follow the CO 2 assimilation and transpiration values.…”

“…Other studies have evaluated plant spacing as a form of control [7,14]. The nutrient dynamics in eucalyptus biomass are particularly reported in young plants, still seedlings, at 110 days after transplantation [3,15], and no study has evaluated the impacts of weeds on biomass production, stock, and nutrient utilization efficiency in eucalyptus stands over 48 months old.…”
