Soil nutrient removal by four potential bioenergy crops: Zea mays, Panicum virgatum, Miscanthus×giganteus, and prairie
Replacing annual row crops with perennial grasses for bioenergy represents a landscape-level change in species composition, with the potential to impact annual soil nutrient removal on a regional scale. In this study we measured the concentration of ten essential nutrients in harvested material from three potential perennial bioenergy crops: Panicum virgatum L., Miscanthus giganteus, and a rees...
متن کاملBioenergy crops Miscanthus x giganteus and Panicum virgatum reduce growth and survivorship of Spodoptera frugiperda (Lepidoptera: Noctuidae).
Large-scale cultivation of plants used as biofuels is likely to alter the ecological interactions of current agricultural crops and their insect pests in a myriad of ways. Recent evidence suggests many contemporary maize pests will be able to use potential biofuel crops such as switchgrass, Panicum virgatum L., and miscanthus as hosts. To determine how suitable these biofuels are to the maize, ...
متن کاملRust Diseases on Switchgrass (Panicum virgatum)
Switchgrass (Panicum virgatum) is a perennial C 4 grass native to the central prairies of North America. Recent development of switchgrass as a sustainable biofuel feedstock has raised interest in diseases that could impact switchgrass, especially when grown under monoculture conditions. Among the known diseases of switchgrass, rust diseases are the most widespread and could potentially impact ...
متن کاملSilica and nitrogen modulate physical defense against chewing insect herbivores in bioenergy crops Miscanthus x Giganteus and Panicum virgatum (Poaceae).
Feedstock crops selected for bioenergy production to date are almost exclusively perennial grasses because of favorable physiological traits that enhance growth, water use, and nutrient assimilation efficiency. Grasses, however, tend to rely primarily on physical defenses, such as silica, to deter herbivores. Silica impedes processing of feedstocks and introduces a trade-off between managing fo...
متن کاملAdaptations between ecotypes and along environmental gradients in Panicum virgatum.
Determining the patterns and mechanisms of natural selection in the wild is of fundamental importance to understanding the differentiation of populations and the evolution of new species. However, it is often unknown the extent to which adaptive genetic variation is distributed among ecotypes between distinct habitats versus along large-scale geographic environmental gradients, such as those th...
