Reid, C. P. Patrick
RESUMO
The effect of specific levels of induced water stress on the root exudation of 14C from 9-month-old and 12-month-old ponderosa pine (Pinus ponderosa Laws.) seedlings was examined. Polyethylene glycol (PEG-4000) was used to decrease root solution water potentials by 0, −1.9, −2.6, −5.5, −9.6 and −11.9 bars in either aerated 0.25X Hoagland's nutrient solution or aerated distilled water.
