For organic farming, the adaptation of varieties to efficient nutrient-use derived from slow-nutrient-releasing organic fertilizer is of special importance, which is not addressed in conventional selection programmes with no or less inorganic fertilizer [14]. Nutrient-uptake efficiency of plants can be...
Species of parasitic plants also differ with regard to whether they need the host in order to complete their life cycle.Obligate parasiteshave an absolute requirement for a host, whereasfacultative parasites can live and reproduce in the absence of a host. All holoparasites are, by definition, ...
