Leaf hydraulic conductance (KLeaf) is a measure of the efficiency water transport through leaf, which determines physiological parameters such as stomatal conductance, photosynthesis and transpiration rates. One key anatomical structure that supports KLeaf leaf venation, could be subject to evolutionary pressure in dry environments. In this context, it useful assess these traits species from ar...

Wheat yellow-green mutant Jimai5265yg has a more efficient photosynthetic system and higher productivity than its wild type under N-deficient conditions. To understand the relationship between properties grain yield, we conducted field experiment different N application levels. Compared to type, flag leaves had mesophyll conductance, N-use efficiency, photorespiration in without application. Ch...

A four- to seven-fold enhancement of leaf hydraulic conductance by light has been reported in three temperate tree species. The enhancement occurs in the liquid-flow pathway between the petiole and the site of water evaporation. The enhancement occurs within 1 h, and dissipates in darkness over a period of 1 to 10 h depending on species. Here we report light-induced enhancement of leaf hydrauli...

The photocontrol of the functional coupling between photosynthesis and stomatal conductance in the leaf was investigated in gas exchange experiments using monochromatic light provided by lasers. Net photosynthesis and stomatal conductance were measured in attached leaves of Malva parviflora L. as a function of photon irradiance at 457.9 and 640.0 nanometers.Photosynthetic rates and quantum yiel...

Using the GECROS model, we simulated effect of improvements in photosynthesis a range growth parameters, including yield, and on εc (the conversion efficiency absorbed solar energy to chemical biomass) εi interception or absorption by canopy) parameters Monteith crop equation, for wheat potato (which use C3 photosynthesis) maize uses C4 photosynthesis). In case crops, were via 20% increases Vcm...

The key function of plant growth regulators is to adjust the and development plants adapt changing environment, which plays a vital role in yield crops. This study was aimed evaluate ability foliar application salicylic acid (SA) abscisic (ABA) regulate rice (Oryza sativa L.) quality at seedling stage reproductive stage. two cultivars Wanshengyoutianhong-4 (W4) Huanghuazhan (HZ) were sprayed wi...

Leaf internal, or mesophyll, conductance to CO(2) (g(m)) is a significant and variable limitation of photosynthesis that also affects leaf transpiration efficiency (TE). Genotypic variation in g(m) and the effect of g(m) on TE were assessed in six barley genotypes (four Hordeum vulgare and two H. bulbosum). Significant variation in g(m) was found between genotypes, and was correlated with photo...
