Root Architecture and Plant Productivity.
Water and nutrient availability limit plant growth in a11 but a very few natural ecosystems. They limit yield in most agricultural ecosystems, and in the United States and other industrialized nations, intensive irrigation and fertilization have generated serious environmental problems. The acquisition of soil resources by plant root systems is therefore a subject of considerable interest in ag...
متن کاملRoot traits contributing to plant productivity under drought
Geneticists and breeders are positioned to breed plants with root traits that improve productivity under drought. However, a better understanding of root functional traits and how traits are related to whole plant strategies to increase crop productivity under different drought conditions is needed. Root traits associated with maintaining plant productivity under drought include small fine root...
متن کامل3D Quantification of Plant Root Architecture In Situ
Root systems play important roles in plant nutrient and water uptake. The spatial distribution and structure of root systems can affect many physiological functions, carbon distribution, and plant anchorage. The accurate measurement of root systems is necessary for better understanding of plant growth and responses to biotic and abiotic stress. Due to their underground growth habitat, root syst...
متن کاملPlant Root
Early recognition of the importance of roots for drought resistance, and the diversity in rice root architecture, provided a strong foundation for drought research at the International Rice Research Institute (IRRI). IRRI was founded in 1960, and large efforts for research on root growth in response to drought were ongoing by the mid-1970s, with an emphasis on deep root growth, formation of coa...
متن کاملBelowground fine root productivity, traits, and trees.
A long-standing debate in plant ecology is how plant diversity – including species richness, functional, and phylogenetic diversity – determines primary productivity aboveground and belowground (Tilman et al., 1997; Cadotte et al., 2009). A leading mechanism linking diversity and productivity posits that diverse assemblages of plants are more likely to complement each other in resource acquirin...
