Última Perspectives for using light quality knowledge as an advanced ecophysiological weed management tool Planta Daninha Merotto Jr.,A.; Fischer,A.J.; Vidal,R.A.. The current knowledge of light quality effects on plant morphogenesis and development represents a new era of understanding on how plant communities perceive and adjust to available resources. The most important consequences of light quality cues, often mediated by decreasing in red far-red ratios with respect to the spectral composition of incident sunlight radiation, affecting weed-crop interaction are the increased plant height and shoot to root ratio in anticipation of competition by light quantity, water or nutrients. Although the concepts related to light quality have been extensively studied and several basic process of this phenomenon are well known, little applications of photomorphogenic signaling currently are related to agricultural problems or...

DE; GIANCOTTI,PAULO R.F.; ALVES,PEDRO L.C.A.; GONÇALVES,ELAINE C.P.; MARTINS,JOSÉ V.F.. Rubber tree production is reduced by weeds that compete for environmental resources; therefore, the timing and duration of weed control influences weed interference. The objectives of this study were to evaluate the growth of rubber tree (Hevea brasiliensis) plants, to determine the critical period for weed control, and to evaluate the growth recovery of rubber trees that coexisted with weeds for different periods of time after planting. Two groups of treatments were established under field conditions in the first year of the investigation: one group contained crescent periods of weed infestation, while the other contained crescent periods of weed control, also including a weed-free check and a total weedy check. In the second year of the investigation,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hevea brasiliensis; Weed interference; Critical period for weed control; Growth recovery.
