“…In general highest values of weight were observed in autumn. These data seem to indicate that the effect can be dependent on the integral thermal with reduced cell division and cell expansion rate in low temperatures, as suggested elsewhere (Klopotek & Klaring, 2014). Thus, in autumn the weight is greater with 2900 ºCd and in spring it was lower with 2400 ºCd.…”

“…In the case of ʽLazarinoʼ higher values of chlorogenic acid, gallic acid, quercetin and total phenolics, were observed, which may be due in part to that high temperatures can increase the photosynthesis, as suggested elsewhere (Klopotek & Klaring, 2014). However, in this study it was also observed that the effect was dependent on the variety as ʽSummerbrixʼ had different behavior.…”

“…In general, lower levels of individual and total carotenoids were observed in autumn. In relation to this, it is thought that low temperatures and short photoperiod can decrease photosynthesis (Klopotek & Klaring, 2014;Gerszberg, Hnatuszko-Konka, Kowalczyk, & Kononowicz, 2015).…”

Nitrogen Limited Red and Green Leaf Lettuce Accumulate Flavonoid Glycosides, Caffeic Acid Derivatives, and Sucrose while Losing Chlorophylls, Β-Carotene and Xanthophylls

Reduction of nitrogen application in crop production is desirable for ecological and health-related reasons. Interestingly, nitrogen deficiency can lead to enhanced concentrations of polyphenols in plants. The reason for this is still under discussion. The plants’ response to low nitrogen concentration can interact with other factors, for example radiation intensity. We cultivated red and green leaf lettuce hydroponically in a Mediterranean greenhouse, supplying three different levels of nitrogen (12 mM, 3 mM, 0.75 mM), either in full or reduced (-50%) radiation intensity. In both red and green lettuce, we found clear effects of the nitrogen treatments on growth characteristics, phenolic and photosynthetic compounds, nitrogen, nitrate and carbon concentration of the plants. Interestingly, the concentrations of all main flavonoid glycosides, caffeic acid derivatives, and sucrose increased with decreasing nitrogen concentration, whereas those of chlorophylls, β-carotene, neoxanthin, lactucaxanthin, all trans- and cis-violaxanthin decreased. The constitutive concentrations of polyphenols were lower in the green cultivar, but their relative increase was more pronounced than in the red cultivar. The constitutive concentrations of chlorophylls, β-carotene, neoxanthin, all trans- and cis-violaxanthin were similar in red and green lettuce and with decreasing nitrogen concentration they declined to a similar extent in both cultivars. We only detected little influence of the radiation treatments, e.g. on anthocyanin concentration, and hardly any interaction between radiation and nitrogen concentration. Our results imply a greater physiological plasticity of green compared to the red lettuce regarding its phenolic compounds. They support the photoprotection theory regarding anthocyanins as well as the theory that the deamination activity of phenylalanine ammonia-lyase drives phenylpropanoid synthesis.

“…Given that the leaf dry matter (DM) content in Moneymaker was unaffected by SOT ( Supplementary Figure 1A,B), the reduction of SLA was likely offset by the increase in leaf thickness. According to Hoek et al (1993) the larger size of the cells at SOT is the cause of the increase in leaf thickness, and these larger cells are able to store more starch (Venema et al 1999a, Klopotek andKläring 2014). In addition, the increase in leaf thickness and total protein concentration has been suggested to be connected to acclimation to low temperature (Pyl et al 2012).…”

Exploring natural variation in sucrose metabolism to improve tomato growth and development at sub-optimal temperature

Plant growth, development and yield of current tomato cultivars are directly affected by low temperatures. Although wild tomato species have been suggested as a potential source for low temperature tolerance, very little is known about their behaviour during the reproductive phase. Here we investigated the impact of suboptimal temperatures (SOT, 16/14˚C), as compared to control temperatures (CT, 22/20˚C), on plant growth, photosynthetic capacity, and carbohydrate metabolism. Under these conditions, two genotypes were analysed: a Solanum lycopersicum cultivar Moneymaker and a high altitude wild species Solanum arcanum LA385, from flowering onset until a later stage of fruit development. Total dry matter production in cv Moneymaker was reduced up to 30% at SOT, whereas it was hardly affected in wild accession LA385. Specific leaf area, total leaf area, and number of fruits were also decreased at SOT in cv Moneymaker. In contrast wild accession LA385 showed an acclimation to SOT, in which Φ PSII and net CO 2 assimilation rates were less affected, a similar specific leaf area, higher total leaf area, and higher number of fruits compared to those at CT. In addition, LA385 appeared to have a more distinct sucrose metabolism than cv Monemaker at both temperatures, in which it had higher contents of sucrose-6-phosphate, sucrose, and ratio of sucrose: starch in leaves and higher ratio of sucrose: hexose in fruits. Overall our findings indicate that wild accession LA385 is able to acclimate well to SOT during the reproductive phase, whereas growth and development of cv Moneymaker is reduced at SOT.
