| Zusammenfassung: | Changes in moisture contents, dry matter, water components, and water dencits of year-old needles from 20-year-old Engelmann spruce (Picea engelmanni Parry) were followed for 1 year in northern New Mexico Moisture percentages reached a seasonal high in March and a low before budbreak in June The decline was associated primarily with an increase in dry matter Dry matter then declined, while moisture percentage increased from June until early August. Subsequent fluctuations in dry matter and water components were minor Water deficits were highest during the primary growing season June through October |
