Metabolic profiling reveals altered nitrogen nutrient regimes have diverse effects on the metabolism of hydroponically-grown tomato (Solanum lycopersicum) plants.
The role of inorganic nitrogen assimilation in the production of amino acids is one of the most important biochemical processes in plants. For this reason, a detailed broad-range characterization of the metabolic response of tomato (Solanum lycopersicum) leaves to the alteration of nitrate level was performed. Tomato plants were grown hydroponically in liquid culture under three different nitra...
متن کاملRelationships between root diameter, root length and root branching along lateral roots in adult, field-grown maize.
BACKGROUND AND AIMS Root diameter, especially apical diameter, plays an important role in root development and function. The variation in diameter between roots, and along roots, affects root structure and thus the root system's overall foraging performance. However, the effect of diameter variation on root elongation, branching and topological connections has not been examined systematically i...
متن کاملTomato chlorotic spot virus in Hydroponically-Grown Lettuce in São Paulo State, Brazil
In the regions of Campinas and Sumaré, São Paulo, Brazil, hidroponically grown crops of Lettuce (Lactuca sativa) cv. Verônica, which showed virus-like symptoms were examined by electron microscope, biological, serological and molecular tests. Pleomorphic, enveloped particles (80-100 nm in diameter) were always detected in these samples. Experimentally inoculated host plants, including lettuce, ...
متن کاملContrasted responses of Botrytis cinerea isolates developing on tomato plants grown under different nitrogen nutrition regimes
The nutritional status of a plant is known to influence its susceptibility to pathogens. In the case of Botrytis cinerea the role of nitrogen fertilization of various host plants on disease development appears to be variable. This study was carried out to characterize possible variability associated with strains and inoculum density of B. cinerea in its ability to infect leaf-pruning wounds and...
متن کاملDifferential root morphology response to no versus high phosphorus, in three hydroponically grown forage chicory cultivars
Forage chicory is a productive forage resource for eastern North America; however, many soils in the region are acidic and deficient in P and might restrict the widespread use of forage chicory. There is no published information on response of forage chicory to P, or P acquisition strategies for morphologically different chicory cultivars. The literature suggests the following null hypothesis: ...
