Does shoot water status limit leaf expansion of nitrogen‐deprived barley? by Dodd, I. C., Munns, Rana, Passioura, J. B.

“…The role of shoot water status in mediating the decline in leaf elongation rate of nitrogen (N)‐deprived barley plants was assessed. Plants were grown at two…”

Mangroves may salinize the soil and in so doing limit their transpiration rate by Passioura, J.B, Ball, M.C, Knight, J.H

“…1. Mangroves often grow in poorly flushed intertidal muds. When their roots extract water from these muds, they exclude almost all of the salt, so the solution…”

Shoot turgor does not limit shoot growth of NaCl-affected wheat and barley by Termaat, A, Passioura, J.B, Munns, R

“…The aim of this work was to test the hypothesis that the reduced growth rate of wheat and barley that results when the roots are exposed to NaCl is due to…”
