	abstract = {In growth chamber grown individuals of creosotebush (<i>Larrea tridentata</i> DC. Cov.), the dark respiration, net photosynthesis, internal leaf resistance and stomatal and cuticular resistances to H2O and CO2 were not affected (P<0.05) by leaf age.  Net photosynthesis did appear to be reduced in leaves older than 47 d, but this apparent reduction was obscured by the standardization of the photosynthetic rates of change of CO2 and stomatal and cuticular resistances to CO2.  An increase in the apparent rate of leaf senescence and subsequent abscission coincide chronologically with an increase in the rate of new leaf production.},
