“…In durum wheat, the accumulated growth degree days were revealed as playing a crucial role in determining VOC profiles and other quality parameters under investigation. GDD is in fact an integrated time–temperature index that has been applied to forecast crop harvest date, yield, and quality 37 . ASR was important for durum wheat too; indeed ASR, which is an index of quantity of radiation captured, affects the biomass produced by monocrops, and limiting radiation is responsible for abnormalities and disorders in plants 38 .…”

BACKGROUNDClimate changes associated with global warming are increasingly affecting the quality of cultivated crops. Cultivation at different altitudes and similar latitudes may offer an extraordinarily useful opportunity to obtain a diversificated dataset of climate variables and to further investigate their effect on crop quality. This study evaluated the effect of climate indices – temperature, rainfall precipitation and solar radiation data – on commercial parameters and the volatile organic compound (VOC) profile of wheat at harvest.RESULTSThree common and durum wheat varieties, including two heritage wheats, were sown in experimental fields sited at three altitudes for 3 years consecutively, and they were analyzed for their yield, grading parameters, and VOC profiles. The datasets were processed by partial least squares regression (PLS‐R) and the results indicate that summer days (SU25) and diurnal temperature range (ΔT) are the climate indices mainly responsible for the VOC profile changes in both common and durum wheat. Accumulated growth degree days (GDD), consecutive dry days (CDD), and accumulated solar radiation (ASR) induced species‐specific responses. Terpenes represented the chemical class of VOCs most affected by stresses, followed by ketones and alcohols, which were affected by CDD, GDD, and ASR.CONCLUSIONThis study showed a selective response of wheat to abiotic stresses associated with climate variables in terms of VOC synthesis. Its findings may be relevant in several fields, from plant ecology to agronomy and food quality, with implications for local economic strategies. © 2023 Society of Chemical Industry.

“…Esta diferença de valores pode ser atribuídas as condições climáticas de cada local, sendo que as principais variáveis que afetam o desenvolvimento da cultura são a precipitação pluviométrica, temperatura do ar e radiação solar (HOOGENBOOM, 2000), e influência do fotoperíodo, da umidade do ar e do solo (PEREIRA et. al., 2002;MAVI, TUPPER, 2004), além do material genético selecionado.…”

O preparo em solo coeso melhora as características físicas do solo e promove maior produtividade. O trabalho avaliou o desenvolvimento inicial do eucalipto sob diferentes preparos do solo: subsolagens 1,10 m; 0,90 m e 0,60 m de profundidade e plantio direto com dimensões de 0,30 x 0,30 x 0,30 m. O experimento foi instalado em delineamento experimental inteiramente casualizado (DIC), com 4 repetições com 25 plantas, em Argissolo amarelo no município Esplanada-BA. Sendo analisado aos 1,3 anos de idade da cultura: altura (H), diâmetro a 1,3m de altura (DAP), volume individual (Vi), volume por hectare (Vha) e incremento médio anual (IMA). O experimento apresentou diferenças significativas, sendo que a subsolagem obteve altura (20,8%), DAP (14,8%), Vi (72,7%), Vha (68%) e IMA (68,1%) maior que o plantio direto (preparo por cova). Desse modo, a subsolagem se apresenta como o preparo do solo mais adequado para o desenvolvimento inicial do eucalipto, não sendo observadas diferenças entre as profundidades das subsolagens até a idade de 1,3 anos.

“…PPFD was calculated utilizing data on the average hourly solar radiation (

) obtained from four weather stations [ 40 ] surrounding the study site. We applied the factor

to convert the hourly solar radiation from

and then applied

to convert solar radiation to PPFD [ 41 , 42 ]. We obtained PFT from the forest map provided by the Korea Forest Service [ 43 ] and also estimated LAI values from the normalized difference vegetation index (NDVI) using the empirical equation suggested by Jang et al [ 44 ], which is adequate for South Korea.…”

(1) Background: Recent economic developments in South Korea have shifted people’s interest in forests from provisioning to cultural services such as forest healing. Although policymakers have attempted to designate more forests for healing purposes, there are few established standards for carrying out such designations based on the quantified estimation. (2) Methods: We suggest a modeling approach to estimate and analyze the emission rate of human-beneficial terpenes. For this purpose, we adopted and modified the Model of Emissions of Gases and Aerosols from Nature (MEGAN), a commonly used biogenic volatile organic compounds (BVOCs) estimation model which was suitable for estimating the study site’s terpene emissions. We estimated the terpene emission rate for the whole year and analyzed the diurnal and seasonal patterns. (3) Results: The results from our model correspond well with other studies upon comparing temporal patterns and ranges of values. According to our study, the emission rate of terpenes varies significantly temporally and spatially. The model effectively predicted spatiotemporal patterns of terpene emission in the study site. (4) Conclusions: The modeling approach in our study is suitable for quantifying human-beneficial terpene emission and helping policymakers and forest managers plan the efficient therapeutic use of forests.
