Abstract The lack of adequate vertical mixing is one the factors limiting productivity open raceway microalgae reactors. existence large gradients light involves cells being mainly adapted to local irradiance instead average irradiance, which would allow for maximizing utilization efficiency, thus biomass cultures. To overcome this problem, different alternatives have been proposed, more suitab...
The response of the marine diatom Phaeodactylum ,tricornutum to Fe deficiency was evaluated in the context of fundamental physiological models of growth and photosynthesis. Fe deficiency induced chlorosis, which decreased Chl a : C ratios and Chl a-specific light-saturated photosynthesis (P,“). In contrast to Pme, (Ye was slightly increased under Fe deficiency, and photosynthesis in Fedeficient...
This study was conducted to evaluate the response of germination, seedling growth and antioxidant enzymes activity 15 chickpea cultivars to salinity at the University of South Korea Dankook a factorial experiment in a randomized complete block design with four replications. The treatments include chickpea cultivars and, salinity levels of water (water with electrical conductivity 0.7 dS/m as a ...
Beneficial effect of titanium on plant growth, photosynthesis and nutrient trait of tomato cv. Foria
ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...
(Assimilate partitioning in leaves of the raffinose-storing herb Lamium album L.: photosynthesis and carbon partitioning throughout the photoperiod). Lamium album accumulates starch, sucrose and raffinose-family oligosaccharides (RFO) as the major products of photosynthesis. These products were measured in leaves throughout a sixteen-hour photoperiod and under various irradiance conditions. The...
In rice (Oryza sativa L.), leaf photosynthesis is known to be highly correlated with stomatal conductance; however, it remains unclear whether stomatal conductance dominantly limits the photosynthetic rate. SLAC1 is a stomatal anion channel protein controlling stomatal closure in response to environmental [CO(2)]. In order to examine stomatal limitations to photosynthesis, a SLAC1-deficient mut...
The rates of true and apparent photosynthesis of two unicellular green algae, one diatom and four blue-green algae were measured in buffer at pH 8.0 at subsaturating concentrations of dissolved inorganic carbon (13-27 micromolar). Initial rates of depletion from the medium of inorganic carbon and (14)C activity caused by the algae in a closed system were measured by gas chromatography and by li...
