Pore size regulates operating stomatal conductance, while stomatal densities drive the partitioning of conductance between leaf sides.
BACKGROUND AND AIMS Leaf gas exchange is influenced by stomatal size, density, distribution between the leaf adaxial and abaxial sides, as well as by pore dimensions. This study aims to quantify which of these traits mainly underlie genetic differences in operating stomatal conductance (gs) and addresses possible links between anatomical traits and regulation of pore width. METHODS Stomatal r...
متن کاملStomatal clustering in Begonia associates with the kinetics of leaf gaseous exchange and influences water use efficiency
Stomata are microscopic pores formed by specialized cells in the leaf epidermis and permit gaseous exchange between the interior of the leaf and the atmosphere. Stomata in most plants are separated by at least one epidermal pavement cell and, individually, overlay a single substomatal cavity within the leaf. This spacing is thought to enhance stomatal function. Yet, there are several genera nat...
متن کاملStomatal conductance does not correlate with photosynthetic capacity in transgenic tobacco with reduced amounts of Rubisco.
High-resolution imaging of chlorophyll a fluorescence from intact tobacco leaves was used to compare the quantum yield of PSII electron transport in the chloroplasts of guard cells with that in the underlying mesophyll cells. Transgenic tobacco plants with reduced amounts of Rubisco (anti-Rubisco plants) were compared with wild-type tobacco plants. The quantum yield of PSII in both guard cells ...
متن کاملLeaf Anatomy of the Goetzeaceae
ABSTRAcr A comparative study of the leaf anatomy ofthree species of three genera of Goetzeaceae (Henoonia, Goetzea, and Espadaea) revealed a number of characteristics common to all genera, viz. anomocytic stomata, sinuous anticlinal epidermal walls, both glandular and uniseriate nonglandular trichomes, crystal sand and druses in the mesophyll (often in the same cell), and intraxylary phloem. Th...
متن کاملTAXONOMIC VALUE OF LEAF ANATOMY IN IRANIAN FINE-LEAVED FESTUCA
Festuca L. comprises perennial herbs and about 450 species. It belongs to the tribe Poeae R. Br. (= Festucaceae Dumort), subfamily Pooideae of Poaceae. These species are different in leaf size, life duration and lamina width. The genus is divided into two groups based on lamina width: fine-leaved and broad-leaved. In this study, leaf anatomy of F. akhanii, F. elwendiana,F. heterophylla, F. sulc...
