The mechanism of leaf morphogenesis.

abstract：:Hydraulic resistances to water flow have been determined in the cortex of hypocotyls of growing seedlings of soybean (Glycine max L. Merr. cv. Wayne). Data at the cell level (hydraulic conductivity, Lp; half-time of water exchange, T 1/2; elastic modulus, ɛ; diffusivity for the cell-to-cell pathway, D c) were obtained...
