Mineral nutrient homeostasis is essential for plant growth and development. Recent research has demonstrated that the occurrence of interactions among the mechanisms regulating the homeostasis of different nutrients in plants is a general rule rather than an exception. Therefore, it is important to understand how plants regulate the homeostasis of these elements and how multiple mineral nutrien...
A recent trial found that the presence of coarse soil in fine soil increased nutrient uptake by two plant species (Smaill et al., 2014). To determine if the additional nutrient uptake was derived directly from the coarse soil, the changes in coarse soil nutrient stocks were assessed. In most cases nutrient stocks increased, despite being associated with greater plant nutrient uptake. This sugge...
Optimum nutrition is one the most effective strategies in floriculture industry. In this regard, a factorial experiment designed based on CRD with three replications on New Guinea impatiens in greenhouse. Treatments were slow release fertilizer (12-11-18-2.7MgO-8S) at 5 levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid at three levels (0, 2 and 4 kg/m3), mixed with substrate. The F1 seeds of N...
Silicon (Si) is one of the beneficial elements for plants, which improves quantity and quality of yield, decreases evaporation and transpiration and enhances plant resistance to abiotic stresses. In order to evaluate the effect of Si and nano-silicon (N-Si) on growth, morphological and photosynthesis attributes of tomato, cultivar Falcato, an experiment was carried out in a hydroponic system, ...
in this study, effect of irrigation duration on concentration of some macro and micro nutrient elements in ‘thompson navel’ orange leaves grafted on three rootstocks was evaluated as a factorial experiment in completely randomized block design. factors included rootstocks in three levels (poncirus trifoliata, citrus aurantium and troyer citrange (citrus sinensis ´ poncitus trifoliata)) and irri...
Trees with sufficient nutrition are known to allocate carbon preferentially to aboveground plant parts. Our global study of 49 forests revealed an even more fundamental carbon allocation response to nutrient availability: forests with high-nutrient availability use 58 ± 3% (mean ± SE; 17 forests) of their photosynthates for plant biomass production (BP), while forests with low-nutrient availabi...
Application of nitrogen sources in nutrient solution of soilless culture systems is one of the important factors in rose production. In order to investigate the effects of different ratios of nitrogen (N) source in nutrient solution on mineral concentration and vase life of rose (Rosa hybrid L. cv Dolcvita), an experiment was conducted as a randomized complete block design in a commercial green...
− Nutrient acquisition by plants occurs in an environment characterized by complex interactions between roots, micro-organisms and animals, termed the rhizosphere. Competition for mineral elements in this sphere is high. The rhizosphere processes are driven by photosynthetically fixed carbon released by roots either directly to mycorrhizal fungal symbionts or as exudates fuelling a wider spectr...
