Abstract
Application of a heat girdle near the base of the lamina of the 5th, fully expanded leaf of 15-day-old plants of P. americanum cv. BJ 104 decreased solute potential, increased leaf DM content and decreased stomatal conductance and the rate of CO2 assimilation. Total water potential was unaffected while turgor potential increased. Leaf ABA content increased 5- to 6-fold within 1 h of girdling, then declined rapidly before increasing again at a slower rate. Girdled leaves were exposed to 14 h of continuous light or continuous darkness followed by a brief light treatment; girdling reduced conductance equally following darkness or light, but solute accumulation occurred only in the light. ABA accumulated in girdled leaves in both darkness and light. There was no increase in intercellular CO2 conc. following girdling. It was concluded that the decreased conductance after girdling was probably mediated by the increase in ABA content
