“…Similar values of F PSII /F CO2 have been previously reported in other low-temperature-grown Z. mays cultivars (Pietrini and Massacci 1998; Leipner et al 1999) and Leipner et al (1999) similarly concluded that alternative electron sinks do not function under these conditions. In contrast, other reports show alternative energy sinks functioning in low-temperature-grown Z. mays (Andrews et al 1995;Fryer et al 1998).…”

“…In the absence of alternative sinks of energy, whole-chain electron transport through PSII is directly proportional to the rate of CO 2 assimilation in C 4 photosynthesis. If there are non-photosynthetic sinks for energy, e.g., Mehler reactions or photorespiration, then the intercept of the relationship between F PSII versus F CO2 will be positive (Andrews et al 1995). In C 4 species, the Mehler reaction may be a more significant source of alternative electron flow to oxygen than photorespiration; however, data on intact leaves is limited (Laisk and Edwards 1998;Badger et al 2000).…”

“…Although low, photorespiration is a competing alternate photochemical energy pathway that can operate within C 4 species and is therefore a potential factor that may decrease efficiency (e.g., Dai et al 1993Dai et al , 1996Maroco et al 1997Maroco et al , 2000Laisk and Edwards 1998). Also, Z. mays grown at low temperatures has been shown to develop large alternative sinks for electron transport, possibly associated with the Mehler reaction (Andrews et al 1995;Fryer et al 1998). Siebke et al (2003) reported that non-photorespiratory lightdependent O 2 uptake at high CO 2 concentrations was, on average, 18% of gross O 2 evolution for several NAD-ME and NADP-ME grass species, suggesting a high capacity for the Mehler reaction in C 4 grasses.…”

Miscanthus x giganteus (Greef & Deuter ex Hodkinson & Renvoize) is unique among C4 species in its remarkable ability to maintain high photosynthetic productivity at low temperature, by contrast to the related C4 NADP-malic enzyme-type species Zea mays L. In order to determine the in vivo physiological basis of this difference in photosynthesis, water vapor and CO2 exchange and modulated chlorophyll fluorescence were simultaneously monitored on attached leaf segments from plants grown and measured at 25/20 degrees C or 14/11 degrees C (day/night temperature). Analysis of the response of photosynthesis to internal CO2 concentration suggested that ribulose bisphosphate carboxylase/oxygenase (Rubisco) and/or pyruvate orthophosphate dikinase (PPDK) play a more important role in determining the response to low temperature than does phosphoenolpyruvate carboxylase (PEPc). For both species at both temperatures, the linear relationship between operating efficiency of whole-chain electron transport through photosystem II (Phi(PSII)) and the efficiency of CO2 assimilation (Phi(CO2)) was unchanged and had a zero intercept, suggesting the absence of non-photosynthetic electron sinks. The major limitation at low temperature could not be solely at Rubisco or at any other point in the Calvin cycle, since this would have increased leakage of CO2 to the mesophyll and increased Phi(PSII)/Phi(CO2). This in vivo analysis suggested that maintenance of high photosynthetic rates in M. x giganteus at low temperature, in contrast to Z. mays, is most likely the result of different properties of Rubisco and/or PPDK, reduced susceptibility to photoinhibition, and the ability to maintain high levels of leaf absorptance during growth at low temperature.

“…Only the value of the coefficient of photochemical quenching (qP) in lemon leaves was different, where the lowest level of this parameter was noted in density classes IV and V. The maximum quantum efficiency of PSII of the dark-adapted leaves indicates the efficiency of the photochemical system, specifically, how much captured light energy is being used by the reaction centre and propagated through the photoelectron transport chain. Measuring F v /F m provides a rapid method for determining changes in the maximum efficiency of PSII photochemistry (Andrews et al 1995). The relative decrease in F v /F m has also been used in the rapid assessment of plant susceptibility or resistance to aphids (Blanco et al 1992).…”

The aim of this experiment was to determine plant responses to Coccus hesperidum L. infestation on two host plants. Groups of five lemon and five fern plants were colonised by various numbers of mobile C. hesperidum instar nymphs. After 6 months, all scale insect individuals were counted on each plant. According to the insect density, the plants were divided into a five-degree series. In all density classes of host plants tested, the infestation of scale insects decreased the chlorophyll and carotenoid content as well as the value of three indicators of photosynthetic activity. The strongest decrease in the analysed pigments was observed for the smallest abundance of insects (firstclass density) in lemon leaves and in second-class density in fern leaves. The strongest reactions of the chlorophyll fluorescence indicators were observed in density classes III and IV in the fern leaves and density classes IV or V in the lemon leaves. The reactions depended on the specific properties of plants and abundance of insects feeding on them.

“…Estimated using atomic absorption spectroscopy Plant Growth Regul (2013) is widely used as a screening in vivo parameter for stress response in plants (Schreiber et al 1994;Andrews et al 1995;Waldhoff et al 2002;Mallick and Mohn 2003). It has been show that in vivo fluorescence measurements are reliable and fast method used for assessing changes in photosynthetic activity in leaves induced by stress factors, both of natural and anthropogenic origin.…”

We investigated the impact of low zinc (Zn) concentrations in the substare on the onset of flowering in Arabidopsis arenosa (Brassicaceae). Experiments were carried out in controlled conditions using plants from four different populations. The research was aimed to verify experimentally the following hypotheses: (1) Zn content in the growth medium promote the onset of flowering in A. arenosa, (2) Changes in the onset of flowering induced by Zn depend on Zn concentration employed; (3) Zn-induced early onset of flowering is an universal plant response present within the species and is not an effect of stress or physiological adaptation to high Zn content in the environment. Investigated plants were subjected to four different Zn concentrations: 0.4 (control), 155, 775 and 1,550 lM Zn 2? . To asses stress level in investigated plants we calculated biomass accumulation and employed fluorometric methods. Zn content was estimated in shoots using atomic absorption spectroscopy. Differences in the onset of flowering were assessed using Kaplan-Meier curves. Our results showed that Zn was transported form growth medium to roots and shoots of investigated plants and that the content of Zn increased with the increase of Zn concentration in the growth medium. We evidenced that apart from one (1,550 lM Zn 2? ) applied Zn concentrations did not caused stress in investigated plants what was confirmed by two independent experimental approaches: measurement of biomass accumulation and chlorophyll a fluorescence. Flowering curves obtained on the basis of calculation of Kaplan-Meier estimator showed that: (1) control plants originating from four different populations did not differ in terms of the onset of flowering, (2) plants from each population tested tends to enter flowering phase earlier in response to applied Zn concentrations than control plants, (3) plants treated with the lowest tested Zn concentration (155 lM Zn 2? ) tend to flower earlier than plants treated with the higher concentration (775 lM Zn 2? ), (4) the impact of Zn on the onset of flowering did not depend on the origin on the plant material used (Zn-rich or Zn-poor soils). Our results indicate that Zn ions present in the growth medium promote early flowering in A.arenosa and that this effect may depend on Zn concentration used. Zn-induced early flowering in A. arenosa seems to be an universal plant response present within the species and is not an effect of stress or physiological adaptation to high Zn content in the environment.
