چکیده
We invest igated the effects of ozone and leaf senescence on steady-state stomatal conductance and stomatal response to light variat ion. Measurements were carried out in a free -air ozone exposure experiment on a representat ive deciduous broadleaved tree species in Japan (Fagus crenata). Both steady-state and dynamic stomatal response to light variat ion varied intrinsically with season due to leaf senescence. Ozone induced the decrease in steady-state leaf gas exchange and the sluggish stomatal closure progressively. These findings suggest that ozone reduces the ability of plants to adapt to a fluctuat ing light environment under natural condit ions, and therefore impairs plant growth and ability to control water loss.

متن کاملPhotosynthetic traits of Siebold's beech and oak saplings grown under free air ozone exposure in northern Japan.
We set up a free-air ozone (O(3)) exposure system for determining the photosynthetic responses of Siebold's beech (Fagus crenata) and oak (Quercus mongolica var. crispula) to O(3) under field conditions. Ten-year-old saplings of beech and oak were exposed to an elevated O(3) concentration (60 nmol mol(-1)) during daytime from 6 August to 11 November 2011. Ozone significantly reduced the net pho...
متن کاملIncreased phytotoxic O3 dose accelerates autumn senescence in an O3-sensitive beech forest even under the present-level O3
Ground-level ozone (O3) concentrations are expected to increase over the 21(st) century, especially in East Asia. However, the impact of O3 has not been directly assessed at the forest level in this region. We performed O3 flux-based risk assessments of carbon sequestration capacity in an old cool temperate deciduous forest, consisting of O3-sensitive Japanese beech (Fagus crenata), and in a wa...
متن کاملOzone-induced stomatal sluggishness changes carbon and water balance of temperate deciduous forests
Tropospheric ozone concentrations have increased by 60-100% in the Northern Hemisphere since the 19(th) century. The phytotoxic nature of ozone can impair forest productivity. In addition, ozone affects stomatal functions, by both favoring stomatal closure and impairing stomatal control. Ozone-induced stomatal sluggishness, i.e., a delay in stomatal responses to fluctuating stimuli, has the pot...
متن کاملUse of sap flow measurements to validate stomatal functions for mature beech (Fagus sylvatica) in view of ozone uptake calculations.
For a quantitative estimate of the ozone effect on vegetation reliable models for ozone uptake through the stomata are needed. Because of the analogy of ozone uptake and transpiration it is possible to utilize measurements of water loss such as sap flow for quantification of ozone uptake. This technique was applied in three beech (Fagus sylvatica) stands in Switzerland. A canopy conductance was...
