Factors Affecting the Emission of Monoterpenes from Red Pine (Pinus densiflora)

Abstract: The mechanism of monoterpene emission from Pinus densiflora was studied using an environmentally controlled gas cabinet. It was found that monoterpene emission rate increases exponentially with temperature and is also influenced by light. These observations were explained reasonably by a mechanism whereby monoterpene emission rate depends on the monoterpene amount in the leaf oil and its saturated vapor pressure.Appreciable quantities of volatile terpenes are emitted into the atmosphere from plants such as con… Show more

“…Seasonal variations in terpene concentrations and emissions have been reported by several authors (Yokouchi and Ambe, 1984;Lerdau et al, 1995;Zou and Gates, 1995) but variations are still not well known. In addition, there is little information on the effect of other factors such as water stress characteristic of summer conditions in Mediterranean ecosystems, in which terpenes are very abundant (Enders, 1994).…”

“…There are also indications that relative humidity (Dement et al, 1975), foliar moisture (Lamb et al, 1985) and precipitation (Helmig et al, 1998) in#uence the emission of monoterpenes from stored pools, but there are currently no quantitative descriptions of these relationships. Seasonal variations in emissions from stored pools may also be signi"cant (Yokouchi and Ambe, 1984) and could be related to variation in resin cell terpene content (Tingey et al, 1991;Lerdau et al, 1995). Monoterpene production rates may be related to the level of wounding or disturbance experienced by the plant (Lewinsohn et al, 1991) but the contribution of wounding-related emissions from resin ducts and glands, relative to the emission from undamaged tissues, is not well characterized.…”
