l azetidine 2 carboxylic acid/zea mays

Exposure to 1 millimolar ammonium pretreatments increased V(max) for phosphorous uptake in dark-grown decapitated maize seedlings without a statistically measurable change in K(m). Sulfate uptake also was stimulated. The stimulation in phosphorous uptake due to ammonium pretreatment was greater in

The effect of anoxia on subsequent uptake and transport of K, Rb, and Na was examined with seedlings of barley (Hordeum vulgare L.), corn (Zea mays L.), and tall fescue (Lolium x Festuca hybrid derivative) to further our understanding of xylem loading. Roots were incubated in solutions depleted of
