Fluoride Exposure Compromises Gas Exchange of Plants

Fluorine (F) stands out for its phytotoxic potential, because it accumulates in plants, changes enzymes activity, reduces chlorophyll content and, consequently, affects growth and yield of crop plants. An experiment was conducted to evaluate the effects of F on leaf gas exchange in coffee and sweet orange plants, compared to sensitive (gladiolus) and tolerant (ryegrass) reference species. Plant...

Structure of arboreal and herbaceous strata in a neotropical seasonally flooded monodominant savanna of Tabebuia aurea.

Large areas in the Pantanal wetland are covered by monodominant formations, e.g. typical landscapes with local names such as "paratudal", dominated by T. aurea. Studies on structure of these formations generally include only woody strata, consequently the species richness registered is usually low due to the absence of the 'ground layer' of herbaceous and others low species. We recorded 13 spec...

Ethylene reduces gas exchange and growth of lettuce plants under hypobaric and normal atmospheric conditions.

Elevated levels of ethylene occur in controlled environment agriculture and in spaceflight environments, leading to adverse plant growth and sterility. The objectives of this research were to characterize the influence of ethylene on carbon dioxide (CO(2)) assimilation (C(A)), dark period respiration (DPR) and growth of lettuce (Lactuca sativa L. cv. Buttercrunch) under ambient and low total pr...

Ethylene Response to Mechanical Stress Perturbation of Salvia Splendens L. Potted Plants

Mechanical treatment could be an efficient method to control growth of vegetable and ornamental species cultivated under greenhouse conditions. Mechanical growth control is able to induce a 20-50% reduction in the vegetative growth depending on the species, the type and intensity of stress applied. In any case, plant growth and morphogenesis are influenced by mechanical perturbation and common ...

Diurnal Variations of Gas Exchange Characteristics in Leaves of Anise Hyssop (Agastache foeniculum) under Normal, Drought Stress and Recovery Conditions

 Net photosynthesis rate (Pn), stomatal conductance (gs) and transpiration rate (E) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (Tleaf), leaf vapor pressure deficit (VPD leaf) and photosynthetic photon flux density (PPFD) in well watered (WW), stressed (S) and recovered (R) plants. An analysis of measured data showed tha...
