Abstract
Heat pulse velocity was monitored in large grand fir (Abiesgrandis (Dougl.) Lindl.) trees before and after defoliation brought about by aerial spraying with Paraquat. Heat pulse velocity of trees which later became severely defoliated declined rapidly after mid-July to near base values in early September. Heat pulse velocity in mid-August was only 27% of the seasonal maximum rate compared with an expected rate of 70%. Heat pulse velocity in partially defoliated and unsprayed trees declined gradually, reaching minimum values in November.
