The intercellular distribution of vacuolar solutes in the epidermis and mesophyll of barley leaves changes in response to NaCl (1996)

Fricke, Wieland, Leigh, Roger A., Tomos, A.Deri

Concentrations of inorganic and organic solutes were measured in sap extracted from individual mesophyll and epidermal cells of the third leaf of barley. During the development of the third leaf...

Intercellular Compartmentation of Ions in Barley Leaves in Relation to Potassium Nutrition and Salinity (1993)

LEIGH, ROGER A., STOREY, RICHARD

EWENS, MARGOT, LEIGH, ROGER A.

The length of root hairs of wheat (Triticum aestivum L.) growing in Long Ashton nitrate nutrient solution was affected mainly by pH and the concentrations of calcium and nitrate. Root hair length was...

A Comparison of Methods for Measuring Turgor Pressures and Osmotic Pressures of Cells of Red Beet Storage Tissue (1984)
