“…It is well established that the ability of plants to assimilate CO 2 is a function of the rate of electron transfer (Strong et al, 2000). On the other hand, the higher photosynthetic rates at 25 and 35 1C than those at 5 and 15 1C were consistent with the view that algae acclimated at high temperature have a higher capacity for dissipating excess excitation through photosynthesis than that of algae acclimated at low temperature (Falk et al, 1996;Huner et al, 1998). This is the first time a positive correlation has been demonstrated between chlorophyll fluorescence and photosynthetic recovery during rehydration at different temperatures.…”

“…U PSII is determined by the efficiency of excitation energy capture by open reactions centers and by the number of open reaction centers available for photochemical reactions (Schreiber et al 1994). Decreases in the U PSII may result from temperature-induced damage to electron transport processes or from feedback inhibition of PS II activity resulting from temperature-induced reductions in C metabolism (Falk et al 1996;Laisk et al 1998). To distinguish between these alternatives requires additional data on the temperature sensitivity of particular fluorescence parameters (e.g., minimum fluorescence, variable fluorescence, and non-photochemical quenching) in addition to detailed study of gas exchange metabolism (Owens 1994;Laisk et al 1998;Xiong et al 1999;Haldimann and Feller 2004).…”

Every species is limited both geographically and ecologically to a subset of available habitats, yet for many species the causes of distribution limits are unknown. Temperature is thought to be one of the primary determinants of species distributions along latitudinal and altitudinal gradients. This study examined leaf physiology and plant performance under contrasting temperature regimes of sister species of monkeyflower, Mimulus cardinalis and Mimulus lewisii (Phrymaceae), that differ in altitude distribution to test the hypothesis that temperature is the primary determinant of differences in fitness versus altitude. Each species attained greatest aboveground biomass, net photosynthetic rate, and effective quantum yield of photosystem II when grown under temperatures characteristic of the altitudinal range center. Although both species exhibited greater stem length, stomatal conductance, and intercellular CO2 concentration in hot than in cold temperatures, these traits showed much greater reductions under cold temperature for M. cardinalis than for M. lewisii. Survival of M. lewisii was also sensitive to temperature, showing a striking decrease in hot temperatures. Within each temperature regime, the species native to that temperature displayed greatest growth and leaf physiological capacity. Populations from the altitude range center and range margin of each species were used to examine population differentiation, but central and marginal populations did not differ in most growth or leaf physiological responses to temperature. This study provides evidence that M. cardinalis and M. lewisii differ in survival, growth, and leaf physiology under temperature regimes characterizing their contrasting low and high altitude range centers, and suggests that the species' altitude range limits may arise, in part, due to metabolic limitations on growth that ultimately decrease survival and limit reproduction.

“…The trend in biomass accumulation was similar across the varieties. However, the accumulation of biomass in the second cycle of study for both evaluated varieties decreased due to the effect of the climatic conditions recorded in 2016, as they directly influenced the rate of photosynthesis [31,32]. The climate conditions during 2016 were lower than in the 2015 cycle (Figure 1), which resulted in a reduction of biomass accumulation.…”

Determination of Micronutrient Accumulation in Greenhouse Cucumber Crop Using a Modeling Approach

Abstract:The control of micronutrient application in cucumber cultivation has great importance as they participate in many functions of metabolism. In addition, micronutrient application efficiency is fundamental to avoid periods of overconsumption or deficits in the crop. To determine micronutrient accumulation using a dynamic model, two cycles of Vitaly and Luxell cucumber crops were grown. During the development of the crop, micronutrient content (Fe, B, Mn, Cu, and Zn) in the different organs of the cucumber plant was quantified. The model dynamically simulated the accumulation of biomass and micronutrients using climatic variables recorded inside the greenhouse as inputs. It was found that a decrease in photosynthetically active radiation and temperature significantly diminished the accumulation of biomass by the cucumber plants. On the other hand, the results demonstrated that the model efficiently simulated both the accumulation of biomass and micronutrients in a cucumber crop. The efficiency evaluation showed values higher than R 2 > 0.95. This dynamic model can be useful to define adequate strategies for the management of cucumber cultivation in greenhouses as well as the application of micronutrients.
