Abstract
Polyethylene glycol was used to test the effects of water stress on expansion and nitrogen metabolism of the elongation region of young maize leaf blades. Reductions in the rates of elongation occurred shortly after stress imposition at all levels tested. Recovery to the control rate occurred after respective lag periods at stress levels of -1.0 and -3.0 bars, but did not occur at a stress level of -5.0 bars. Water stress did net significantly affect the quantities of nitrogen in three component fr actions extracted from the elongation region, but reduced the synthesis rates in these fractions which were also found to closely follow reductions in the rate of growth. Reductions in the rates of nitrogen syntheses within elongating cells under stress appear to be closely correlated to reductions in the rate of expansion of these cells.
