Analyzing lateral root development: how to move forward.
Roots are important to plants for a wide variety of processes, including nutrient and water uptake, anchoring and mechanical support, storage functions, and as the major interface between the plant and various biotic and abiotic factors in the soil environment. Therefore, understanding the development and architecture of roots holds potential for the manipulation of root traits to improve the p...
متن کاملUnderstanding Root Systems to Improve, Seedling Quality
Root architecture can be very important in plant productivity. The importance of studies on root morphology and development is discussed to improve seedling growth. Root systems of dicotyledonous species are reviewed, with emphasis on differences between growth of basal and lateral roots. The presence of different types of roots in plant species suggests possible differences in function as well...

The unexpected emergence and subsequent pandemic spread of a unique H1N1 virus in 2009 have had many consequences. In many ways, it has tested our global and national pandemic preparedness planning and questioned the underlying assumptions in plans which had been largely prompted by the ongoing epizootic of H5N1 viruses. Nevertheless, that planning provided both the basis and stimulation for st...
متن کاملDevelopment of Douglas-fir seedling root architecture in response to localized nutrient supply
Three months following sowing, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were transplanted into pots with controlled-release fertilizer (CRF) applied at rates of 0, 8, 16, and 24 g/2200 cm3 soil as a single uniform layer beneath the root system. Seedlings were destructively harvested periodically, and roots were divided into vertical segments above (S1), within (S2), and belo...
متن کاملLongleaf Pine Root System Development and Seedling Quality in Response to Copper Root Pruning and Cavity Size
rootcollar diameter as the standard, nondestructive measure of seedling quality. Other nondestructive measures of seedling quality would be valuable. One option, root-bound index (RBI), reflects the ratio of rootcollar and cavity diameters (South et al. 2005, South and Mitchell 2006). This variable is an indirect, nondestructive measure of how well the cavity accommodates both the taproot and f...
