Growth and development responses to UV-B exclusion in crops
UV-B radiation affects crop plants. Growing interest has been shown in studying the effectsof UV-B radiation exclusion on crops since 1993. This article summarized the generalconsequences of UV-B radiation exclusion on crop plants from the aspacts of plant morphology,growth and development. UV-B exlusion has promoting effects on plant height, internodeand leaf size. UV-B exclusion increases roo...

متن کاملA comparative analysis of transcriptomic, biochemical, and physiological responses to elevated ozone identifies species-specific mechanisms of resilience in legume crops
Current concentrations of tropospheric ozone ([O3]) pollution negatively impact plant metabolism, which can result in decreased crop yields. Interspecific variation in the physiological response of plants to elevated [O3] exists; however, the underlying cellular responses explaining species-specific differences are largely unknown. Here, a physiological screen has been performed on multiple var...
متن کاملImpacts of ozone on trees and crops
In this review article, we explore how surface-level ozone affects trees and crops with special emphasis on consequences for productivity and carbon sequestration. Vegetation exposure to ozone reduces photosynthesis, growth, and other plant functions. Ozone formation in the atmosphere is a product of NOx, which are also a source of nitrogen deposition. Reduced carbon sequestration of temperate ...
متن کاملPhysiological and morphological responses of olive plants to ozone exposure during a growing season.
We studied physiological (gas exchange and stomatal aperture) and morphological (individual leaf area and stomatal density) responses in leaves of five-year-old olive plants (Olea europaea L. cvs. Frantoio and Moraiolo) exposed to filtered air containing < 3 ppb O(3) or 100 ppb O(3) for 5 h day(-1) for 120 days in fumigation chambers. After 100 days of treatment, leaf drop and development of ne...
