22Na+and36Cl−mobility in salinized excised leaves of several crop plants

Organ-dependent oxylipin signature in leaves and roots of salinized tomato plants (Solanum lycopersicum).

Oxylipins have been extensively studied in plant defense mechanisms or as signal molecules. Depending on the stress origin (e.g. wounding, insect, pathogen), and also on the plant species or organ, a specific oxylipin signature can be generated. Salt stress is frequently associated with secondary stress such as oxidative damage. Little is known about the damage caused to lipids under salt stres...

Leaf water potential of differentially salinized plants.

Water and osmotic potential energies were measured with thermocouple psychrometers, at intervals during a 4-week period, in growing leaves of bean (Phaseolus vulgaris, var. Blue Lake) and barley (Hordeum vulgare, var. Liberty) plants having roots equally split between 2 differentially salinized nutrient solutions. The osmotic potentials of plants with half their roots in saline solutions were a...

Gaseous Losses of Nitrogen from Green Plants. Ii. Studies with Excised Leaves in Nutrient Media.

In the previous paper (1) of this series, studies to determine whether gaseous losses of nitrogen occur from cultures of Chlorella and Lemna when grown on various sources of nitrogen, showed that no losses occurred except for one minor exception. In this one case slight losses of nitrogen from Chlorella cultures, grown on ammonium nitrate, did occur. The significance of this finding is somewhat...

Biofortification of Crop Plants

Studies in the Metabolism of Crassulacean Plants: the Effect of Temperature upon the Culture of Excised Leaves of Bryophyllum Calycinum.

When Bryophyllum calycimum leaves are detached from the plant and cultured in water in darkness at ordinary room temperature, the course of the changes in composition with respect to the organic acids, the protein and the starch depends upon the time of day at which the samples were collected (5). If leaves are taken in the afternoon at a time of low acidity and low protein content, there is a ...
