SummaryCalcium transport in roots of maize and bean plants.In order to study Ca-transport in roots of intact plants, nutrient solution labelled with Ca45 was supplied to a 3 cm long root zone of 9 days old maize (Zea mays L, Velox) and bean plants (Phaseolus vulgaris L., Saxa). The remainder of the root system (length of the seminal root 25–30 cm) grew in nutrient solution without Ca45. After 1–7 days the distribution of Ca45 was determined in the different root zones and in the shoot. 1.)Ca45… 

Calcium (45Ca) accumulation and transport in chicory (Cichorium intybus L.) root during bud development (forcing)

The lower part (4 cm) of the witloof chicory tap-root (15 cm) was immersed in a complete nutrient solution for 21 days, in the darkness at 18°C and at high RH. This process of forcing which leads to

Calcium-accumulating cells in the meristematic region of grapevine root apices.

It is suggested that the raphide crystals could initially act as another Ca sink involved in the regulation of Ca levels in root apices, and the temporal balance of solute supply from the protophloem and the external medium is interpreted.

Root growth and calcium uptake in relation to calcium concentration

The size of the roots in the test media decreased with decreasing calcium concentration to a certain extent, but the number of roots had an exponential course at all calcium concentrations and was enhanced by increased calcium concentration.

This study has been designed to estimate leaf lifespan, leaf production and leaf death (Ld) rates, the age structure of leaves, and the decline in maximum photosynthetic rate (Amax) with age in plants of Ipomoea pes-caprae growing with a full supply of nutrients and with a low Ca supply.

Plasticity of the Arabidopsis Root System under Nutrient Deficiencies1[C][W][OPEN]

A systematic comparison of RSA responses to nutrient deficiencies provides a comprehensive view of the overall changes in root plasticity induced by the deficiency of single nutrients and provides a solid basis for the identification of nutrient-sensitive steps in the root developmental program.

Response of ‘Jonagold’ Apple Trees in the First Three Years after Planting to Mono-Ammonium Phosphate Fertilization Under Replant Problem Conditions

Abstract The objective of the experiment was to examine response of immature apple trees to application of mono-ammonium phosphate (MAP) fertilizer on replant problem soil. The study was carried out

The influence of humidity on the mineral composition of tomato plants with special reference to calcium distribution

SummaryTomato plants grown in water culture under two different humidity regimes (50% R.H. and 95% R.H.) were harvested at intervals over the growth period and cation uptake and calcium distribution

Nutritional disorders between potassium, magnesium, calcium, and phosphorus in soil

A new soil testing procedure has been used to demonstrate the effect of an overfertilization by potassium during the preceding years. The total concentration of cations was governed by the amount of

Water transport in the xylem as related to calcium uptake by groundnuts (arachis hypogaea L.)

An explanation is offered for the extra-ordinary behaviour of calcium in view of the fact that whilst the xylem is considered to be the main path of conduction for this element the stream of water necessary for its transport is absent.

Short-term, split-root experiments were conducted in a growth chamber with ‘Lee’ soybeans (Glycine max). The upper portion of the root medium was a limed, fertilized sandy loam surface soil; the

The tissue Ca data indicate the presence of multiple systems in the absorption and accumulation of Ca by excised cotton roots, and only the low concentration mechanism for Ca accumulation was associated with growth.

The perfusion design is less susceptible to tracer kinetic errors, and was implemented here for companion studies on Ca and Sr transport isotherms, thus stupplanting the earlier approach based on cup immersion.
