Silicon Uptake Level of Six Potted Plants from a Potassium Silicate-supplemented Hydroponic Solution

Effect of Phosphorus Application in Hydroponic Solution on Growth and Phosphorus Uptake in Chrysanthemum Plants

The relationship between phosphorus (P) uptake and growth rate of chrysanthemum plants grown hydroponically for cut flowers was investigated. In Exp. 1, fresh weight increase of chrysanthemum cv. Seiun plants at flower budding phase administered 0 to 40 ppm in culture solution for 16 days was evaluated. 1. P uptake by the chrysanthemum plants was nearly proportionate to P concentration in the c...

High-Affinity Potassium Uptake Transporter from Higher Plants

High-affinity potassium uptake in plants.

oocyte]. Oocytes were incubated for 24 to 48 hours, treated with coelenterazine [10 ,uM coelenterazine (Molecular Probes, Eugene, OR) and 30 p.M reduced glutathione in OR-2 media (no calcium)] for 2 to 3 hours with gentle orbital shaking in the dark at 18°C, and retumed to ND-86 medium with calcium (maintained in the dark with shaking) until measurements were initiated. For luminometer measurem...

Silicon uptake and accumulation in higher plants.

Silicon (Si) accumulation differs greatly between plant species because of differences in Si uptake by the roots. Recently, a gene encoding a Si uptake transporter in rice, a typical Si-accumulating plant, was isolated. The beneficial effects of Si are mainly associated with its high deposition in plant tissues, enhancing their strength and rigidity. However, Si might play an active role in enh...

Modelling potassium uptake by wheat

A model has been used to simulate potassium (K) uptake by wheat in a pot culture experiment. Three soils from India, namely Alfisol, Inceptisol and Vertisol, were differentially K exhausted by Sudan grass (Surghum vulgare var. Sudanensis) for a period of 280 days and were used to simulate potassium uptake by wheat (Triticum aestivum) and also to predict the amounts of K released or fixed during...
