this research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. applied nutrients were zinc sulphate (zn) of 0.0 and 1.5gl-1 and urea (n) at 0.0 and 5 gl-1 and fe (1) control (low fe)...

In mangrove killifish Rivulus marmoratus, urea excretion (J(urea)) follows a distinct diurnal pattern with the highest rates between 12:00 h and 18:00 h. We investigated the regulating mechanisms that underlie temporal rhythms in J(urea) in R. marmoratus. We hypothesized that the daily pattern of J(urea) in R. marmoratus is (1) due to diurnal changes in urea synthesis rates and ultimately metab...

1 All teleost fish produce ammonia as a metabolic waste product. In embryos, ammonia 2 excretion is limited by the chorion and fish must detoxify ammonia by synthesizing urea via the 3 ornithine urea cycle (OUC). Although urea is produced by embryos and larvae, urea excretion 4 (Jurea) is typically low until yolk sac absorption, increasing thereafter. The aim of this study was 5 to determine th...

Tabernaemontana rotensis (Kaneh.) P.T. Li is an attractive small tree that endemic to the islands of Guam and Rota. Conservation efforts threatened population are constrained by lack research. Understanding ecology flower fruit development fundamental successful conservation angiosperms. This study determined extent induction following tropical cyclone defoliation, tested efficacy 10% urea spra...
