The Role Of Ethylene In Plant Responses To K+ Deficiency, Daniel P. Schachtman
The Role Of Ethylene In Plant Responses To K+ Deficiency, Daniel P. Schachtman
Center for Plant Science Innovation: Faculty and Staff Publications
Potassium is an essential macronutrient that is involved in regulating turgor , in driving plant growth, and in modulating enzyme activation. The changes in root morphology, root function, as well as cellular and molecular responses to low potassium conditions have been studied in the model plant Arabidopsis and in other plant species. In Arabidopsis ethylene plays a key role in roots in the transduction of the low potassium signal, which results in altered root function and growth. The first clues regarding the role of ethylene were detected through transcriptional profiling experiments showing changes in the expression of genes related to …

Our objectives were to document effects of nitrogen (N), phosphorus (P), and potassium (K) fertilizer rates on forage yields and uptake of N, P, and K by Midland bermudagrass [Cynodon dactylon (L.) Pers.] on a Minco fine, sandy loam in southern Oklahoma. After six years of this long-term experiment, forage yield responses to fertilization were mixed and depended on year. Stability analysis indicated forage yields responded positively to N fertilization during favorable weather conditions but negatively during poor weather conditions. Application of 112 kg N ha−1 provided the best yield stability and mean annual forage yield among treatments, …

HiMag, an accession of tall fescue (Festuca arundinacea Schreb.), was selected for high magnesium (Mg) concentration in leaves to reduce grass tetany risk to ruminants. However, the mechanism for enhanced Mg uptake in HiMag leaves has not been determined. The objective was to investigate if increased Mg uptake in HiMag could be explained by differences in elemental distribution among plant parts, root characteristics, or organic acid concentrations compared to its parental cultivars, ‘‘Kentucky 31’’ (KY31) and ‘‘Missouri 96’’ (MO96). The study was conducted on a surface-irrigated calcareous Portneuf silt loam (coarse-silty, mixed, mesic, Durinodic Xeric Haplocalcid). Vegetation and soil …
Fertilization And Improvement Of Native Subirrigated Meadows In Nebraska, P. Ehlers, G. Viehmeyer, R. Ramig, E. M. Brouse
Fertilization And Improvement Of Native Subirrigated Meadows In Nebraska, P. Ehlers, G. Viehmeyer, R. Ramig, E. M. Brouse
Nebraska Agricultural Experiment Station: Historical Circulars
It is the purpose of this circular to summarize the 1948-51 results of fertilizer applications upon subirrigated native meadows. It is upon these lands that the cattleman depends to a large extent for winter feed.
