Drought and ozone stresses affect spruce needle structure
Young spruces were exposed to ozone and drought stress for 4 years in open-top chambers in Sweden. Kivimaenpaa et al. (pp. 779-793) show how drought-induced nutrient imbalance and memory-effects are reflected in cell and tissue structures of needles. They highlight the role of mitochondria, peroxisomes and vacuoles in responses to ozone.
