“…It is evident that other changing environmental factors, such as CO 2 concentration [28,58] and water availability [59,60] will also affect growth and plant architecture of grapevines. Especially growth constraints due to limited water ability drastically affect grapevine shoot architecture (internode length, side shoot growth, leaf size, [21,61,62]) and have to be incorporated into descriptive plant architecture models if climate change effects are to be realistically modelled. Water deficit effects on grapevine growth have not yet been integrated into the virtual Riesling, but will be the next step in model development.…”

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.

“…However, results for grapevine are sparse and sometimes contradictory. Greenhouse experiments have shown a reduced growth under elevated CO 2 [61,62], while field trials using FACE systems have shown the opposite results [28,64]. More research is thus necessary to get reliable field data for modelling CO 2 effects on grapevine growth.…”

“…highlighting the importance of the light environment on berry development. In 16 this report, in order to get a better understanding of how much of the gene 17 expression in Cabernet Sauvignon berry skin could be attributed to 18 environmental influences, we tested the hypothesis that there would be 19 significant differences in gene expression during the late stages of Cabernet 20…”

“…As reported by Ludwig and Vijai Singh (Ludwig et al 2009, Ludwig 2017, Milazzo et al 1994, Singh et al 2017 temperature evaluations have been used to check leaf transpiration as a clue of the good health of greenery. Temperature plays also a key role for the specific case of grapevine, in regulating the chemical-physical features (physiology, phenology and photosynthesis) (Ferrini et al 1995, Kanistras et al 2013, Martínez-Lüscher et al 2016 and the final quality of wine. In fact, temperature affects the development of berries, by inducing a differential accumulation of dry matter and sugar concentration (Costa et al 2010, Gaiotti et al 2018, Greer et al 2014, Idso et al 1981.…”

The paper presents multi-sensor applications of Unmanned Aerial Vehicles (UAVs) on three different cases of study, belonging to the wide category of Cultural Heritage (CH). The contribution aims to examine the efficacy of different methodological approach of surveys made in VIS and TIR range with aerial platforms. The use of UAV on two archaeological areas, Çatalhöyük site (Konya, Turkey) and the Medicean Villa of Pratolino (Florence, Italy) and an application of precision agriculture in Lamole (Greve in Chianti, Italy) will be presented. In particular, the analysis will focus on the accuracy of the obtained data, in terms of both metric and image quality, the possible information to extract from the IR imaging, the relationship between costs and benefits and the total amount of information that can be gained. The two different fields of research (archaeological and agricultural one) show that there are some similarities in the approaches and which could be the improving to obtain using the aerial survey in the visual and IR bands.
