The forests of the San Bernardino Mountains have been subject to ozone and nitrogen (N) deposition for some 60 years. Much work has been done to assess the impacts of these pollutants on trees, but little is known about how the diverse understory flo

summary Seedlings of ponderosa pine (Pinus ponderosa Laws.) were grown for three years under three atmospheric ozone concentrations – clean air (CF), ambient ozone (NF), and 15 times ambient ozone (NF150)–at a moderately-polluted site in the Sier

Toxic effects of photochemical smog on ponderosa and Jeffrey pines in the San Bernardino Mountains were discovered in the 1950s. It was revealed that ozone is the main cause of foliar injury manifested as chlorotic mottle and premature needle senesce

Effects of ozone, dry and wet acidic deposition and climate were studied on tree species and nutrient cycling in a southern California mixed conifer forest from 1991 to 1994 at a location within the plume of photochemical oxidant pollutants transport

A detailed microscopic analyses of the mode of lead uptake and localization in root, stem and leaf initials of corn seedlings grown in cultural solution is reported. Lead, as other minerals, was passively absorbed into the root tip region and transpo

A histochemical staining technique using sodium rhodizonate was developed for detecting lead in living or preserved plant tissues. Sodium rhodizonate formed a bright scarlet-red precipitate with lead at pH 3.0, but showed no significant color respons

summary Nitrogen (N) resorbed from foliage before leaf abscission is a significant source of N for new leaves. The widely distributed photochemical air pollutant ozone (O3) accelerates foliar senescence and leaf abscission and therefore could interfe

Foliar injury symptoms and stem diameter growth were measured on well-watered and drought-stressed ponderosa pine (Pinusponderosa Dougl. ex Laws.) seedlings at the end of each of 3 years of exposure to three levels of ozone: charcoal-filtered air, no
