Future climatic conditions might have severe effects on grapevine architecture, which will be highly relevant for vineyard management decisions on shoot positioning, pruning or cutting. This study was designed to help gaining insight into how, in particular, increasing temperatures might affect grapevine canopies. We developed a functional-structural model for Riesling, Virtual Riesling, based on digitised data of real plants and a comprehensive state-of-the-art data analysis. The model accounts for the variability in temperature-sensitive morphological processes, such as bud break and appearance rates. Our simulation study using historical weather data revealed significant effects of the thermal time course over the year on bud burst of the cane and on primary shoots. High variabilities in these events affect canopy growth and leaf area distribution. This report shows that Virtual Riesling can be useful in assessing the significance of changing temperatures for grapevine architecture and thereby considering management techniques such as vertical shoot positioning. Further developments of Virtual Riesling might support the knowledge gain for developing necessary adaptations in future vineyard management and, thus, facilitate future work on climate change research using functional-structural model approaches.

“…Several experiments were carried out to investigate the responses of biomass and productivity to e[CO 2 ] among different functional groups (Hooper & Vitousek, 1998;Reich et al, 2004). Research shows that the effects of [CO 2 ] are not just presented in cereals (Wohlfahrt, Smith, Tittmann, Honermeier, & Stoll, 2018).

The increasing [CO 2 ] in the atmosphere increases crop productivity. However, grain quality of cereals and pulses are substantially decreased and consequently compromise human health. Meta‐analysis techniques were employed to investigate the effect of elevated [CO 2 ] (e[CO 2 ]) on protein, zinc (Zn), and iron (Fe) concentrations of major food crops (542 experimental observations from 135 studies) including wheat, rice, soybean, field peas, and corn considering different levels of water and nitrogen (N). Each crop, except soybean, had decreased protein, Zn, and Fe concentrations when grown at e[CO 2 ] concentration (≥550 μmol/mol) compared to ambient [CO 2 ] (a[CO 2 ]) concentration (≤380 μmol/mol). Grain protein, Zn, and Fe concentrations were reduced under e[CO 2 ]; however, the responses of protein, Zn, and Fe concentrations to e[CO 2 ] were modified by water stress and N. There was an increase in Fe concentration in soybean under medium N and wet conditions but nonsignificant. The reductions in protein concentrations for wheat and rice were ~5%–10%, and the reductions in Zn and Fe concentrations were ~3%–12%. For soybean, there was a small and nonsignificant increase of 0.37% in its protein concentration under medium N and dry water, while Zn and Fe concentrations were reduced by ~2%–5%. The protein concentration of field peas decreased by 1.7%, and the reductions in Zn and Fe concentrations were ~4%–10%. The reductions in protein, Zn, and Fe concentrations of corn were ~5%–10%. Bias in the dataset was assessed using a regression test and rank correlation. The analysis indicated that there are medium levels of bias within published meta‐analysis studies of crops responses to free‐air [CO 2 ] enrichment (FACE). However, the integration of the influence of reporting bias did not affect the significance or the direction of the [CO 2 ] effects.

“…For example, Bindi et al [4] noted that atmospheric CO 2 enrichment stimulated grapevine growth and enhanced fruit and total biomass. Stimulated growth and yield, as well as enhanced stomatal conductance and transpiration, under elevated CO 2 , were also reported from a vineyard free-air carbon dioxide enrichment (FACE) facility in Geisenheim, Germany [5].…”

“…Higher atmospheric levels of CO 2 have been shown to result in a higher biomass, increased yield, and lower nutritional values in grapevine and other plants [2,5,44]. However, plant tissues and fluids vary in their response to elevated CO 2 [2,3,45] and influence different feeding guilds of herbivores in different ways [3,7].…”

Carbon dioxide (CO 2 ) is one of the primary factors driving climate change impacts on plants, pests, and natural enemies. The present study reports the effects of different atmospheric CO 2 concentrations on the vine mealybug Planococcus ficus (Signoret) and its parasitoid wasp Leptomastix dactylopii (Howard). We investigated the life-history parameters of both species on grapevine Vitis vinifera (L.) plants grown under elevated (eCO 2 ) and ambient (aCO 2 ) CO 2 levels in a greenhouse and in a vineyard free-air carbon dioxide enrichment (FACE) facility. The greenhouse experiments with an eCO 2 level of around 800 ppm showed a significant increase in survival rates, a strong trend towards declining body size, and an increasing fecundity of female mealybugs, while fertility and development time did not change. However, none of these parameters were altered by different CO 2 concentrations in the VineyardFACE facility (eCO 2 level around 450 ppm). On the other hand, the parasitism success, development time and sex ratio of L. dactylopii, reared on P. ficus under eCO 2 or aCO 2 , varied neither in the greenhouse nor in the FACE facility. These results suggest that future CO 2 levels might cause small-scale changes in vine mealybug fitness; however, this is not necessarily reflected by parasitoid performance.Agronomy 2019, 9, 326 2 of 12 while phloem-feeders seem to be less affected. Several studies report an improved aphid fitness under elevated CO 2 (eCO 2 ) [3,8], although the mechanisms behind this are not yet fully understood. While aphids are a primary pest in many agricultural and horticultural systems, mealybugs, such as the vine mealybug Planococcus ficus Signoret (Hemiptera: Pseudococcidae), are a much bigger concern in grapevine production.Planococcus ficus is an invasive phloem-feeding insect from the Mediterranean area, which has become a serious invasive pest in many grape-growing regions worldwide [9,10]. Mealybugs affect grapevines both directly and indirectly. By feeding on the phloem sap of all plant organs, mealybugs weaken the plants' vigour. Furthermore, the excreted honeydew promotes the growth of sooty mould on leaves and fruits, reducing photosynthesis, grape marketability and wine quality [9,11,12]. Planococcus ficus is also known to transmit grapevine leafroll-associated virus (GLRaV) and other diseases, which reduce the crop yield and wine quality [13,14]. Mealybug control was based on repeated applications of broad-spectrum insecticides, although with limited success, as mealybugs feed not only on the canopy, but also under the bark and in the root area [15], where they are inaccessible to contact-active pesticides. Additionally, the reiterated use of broad-spectrum insecticides is associated with negative effects on non-target organisms, including biological control agents, and the risk of future pesticide resistance [10,16,17]. Therefore, alternative methods for mealybug control include employing new pesticides, pheromone-based mating disruption, and biological control [18][19][20][21][...
