Emissions of volatile organic compounds (VOCs) from sunflower (Helianthus annuus L. cv. giganteus) were measured in a continuously stirred tank reactor. The compounds predominantly emitted from sunflower were: isoprene, the monoterpenes α-pinene, β-pinene, sabinene, 3-carene and limonene, an oxygenated terpene, not positively identified so far and the sesquiterpene β-caryophyllene. Emission rates ranged from 0.8 x 10−16 to 4.3 x 10 −15 mol cm−2 s−1 at a temperature of 25°C and at a light… 
Light dependency of VOC emissions from selected Mediterranean plant species.
The light, temperature and stomatal conductance dependencies of volatile organic compound (VOC) emissions from ten plant species commonly found in the Mediterranean region were studied using a fully
Light dependency of VOC emissions from selected Mediterranean plant species
The light, temperature and stomatal conductance dependencies of volatile organic compound (VOC) emissions from ten plant species commonly found in the Mediterranean region were studied using a fully
Observations and models of emissions of volatile terpenoid compounds from needles of ponderosa pine trees growing in situ: control by light, temperature and stomatal conductance
This study shows unequivocally that, under naturally occurring field conditions, de novo light-dependent monoterpenes comprise a significant fraction of emissions in ponderosa pine.
Significant light and temperature dependent monoterpene emissions from European beech (Fagus sylvatica L.) and their potential impact on the European volatile organic compound budget
[1] By using a dynamic branch enclosure system the emission of monoterpenes from European beech (Fagus sylvatica L.) was investigated during two consecutive summer vegetation periods in the years of
Temperature and light dependence of β‐caryophyllene emission rates
[1] Assessments of the overall release of reactive volatile organic compounds from vegetation require the knowledge of the effect of temperature and light intensity on emission rates. The aim of the
Influence of physiological and environmental factors on the diurnal variation in emissions of biogenic volatile compounds from Pinus tabuliformis.
The composition and diurnal variation in emission rates of BVOCs from Pinus tabuliformis are assessed, providing a detailed reference for the effective selection and configuration of tree species to effectively prevent and control atmospheric pollution.
Toluene emissions from plants
The emission of toluene from different plants was observed in continuously stirred tank reactors and in field measurements. For plants growing without stress, emission rates were low and ranged from
Variation in biogenic volatile organic compound emission pattern of Fagus sylvatica L. due to aphid infection.
Volatile organic compounds (VOCs) have been the focus of interest to understand atmospheric processes and their consequences in formation of ozone or aerosol particles; therefore, VOCs contribute to
Methanol emissions from deciduous tree species: dependence on temperature and light intensity.
Methanol emissions from several deciduous tree species with predominantly mature leaves were measured under laboratory and field conditions and indicated that a substantial fraction of the emitted methanol may be produced in the roots or stem and transported to stomata by the transpiration stream.
Monoterpene emissions from Scots pine (Pinus sylvestris): Field studies of emission rate variabilities
[1] Monoterpene emission rates from young and adult Scots pines (Pinus sylvestris), a typical central European conifer, were measured under ambient conditions using a dynamic enclosure chamber. We


Influence of light and temperature on monoterpene emission rates from slash pine.
Emission rates from heat-stressed needles were similar to healthy needles, but rates decreased 11% per day, and carbon loss through monoterpene emissions accounted for approximately 0.4% of the carbon fixed during photosynthesis.
