“…A importância em se conhecer a influência das condições climáticas sobre os processos reprodutivos e, assim, possibilitar o desenvolvimento de tecnologias que minimizem os possíveis efeitos, aumenta à medida que as projeções de aquecimento global são cada vez mais alarmantes, pois, conforme já mencionado, este aumento da temperatura tem influência sobre as plantas, induzindo mudanças em diversos setores, como na época de floração (ROOT et al, 2003;CHMIELEWSKI et al, 2004;FUJISAWA;KOBAYASHI, 2010); no crescimento, maturação e, consequentemente, qualidade pós-colheita de frutos (WARRINGTON et al, 1999); na fotossíntese e na eficiência produtiva da planta pelo aumento elevado de CO 2 (HAN et al, 2012) (EMBRAPA, 2006). A média da precipitação pluvial anual é de 1.670mm, e a umidade relativa do ar média é de 78% (CIRAM/EPAGRI).…”

PHenologicAl evAluAtion of different fruiting HAbits of 'gAlA' And 'fuJi' APPles in tHe soutHern brAZilAbstrAct -Apple shows two distinct phases that characterizes its annual cycle: dormancy and vegetative/ reproductive growth. The importance of knowing the influence of climate conditions on tree reproductive processes and furthermore, developing technologies that minimize the future effects increases upon the global warming predictions becomes concerning. The goal of this study was to characterize the behavior of the main phenological events of apple, from bud break to harvest, on different fruiting habits under the subtropical climatic conditions of the South of Brazil. The experiments were carried out on nine year old 'Gala' and 'Fuji' apples in the Experimental Station of EPAGRI (Brazil -26°50'S, 50°58'W, altitude 950m) during two different growing seasons, 2011/12 and 2013/14. Date and days after dormancy breaking treatment and heat requirements of the main phenological stages from bud break to harvest were evaluated. Evaluations were performed on each fruiting habit: spur buds, terminal and axillary buds on long shoots. Differences found on the onset of bud break and flowering among fruiting habits greatly depended on climate conditions of the particular year. High temperatures conditions after the dormancy breaking treatment induced to a phenological synchrony among fruiting habits, and vice versa. From dormancy breaking treatment, spur buds, especially 'Gala' buds, required less heat accumulation to bud break. Terminal buds of long shoots required higher amount of heat than spur buds to start flowering. index terms: Malus domestica Borkh., degree-days, bud break, flowering.

“…However, berry size was discussed to be related to berry and wine quality [14][15][16][17][18][19][20][21]. Hence, the quality of grapes grown under eCO 2 might be affected.In other perennial fruit crops like pears and sour oranges, enhanced fruit weight, volume, and diameter were detected under eCO 2 [22][23][24]. Soluble solids content of pears was also increased under eCO 2 , but the effect depended on growth stages of the fruit [22,23].…”

The Effect of Elevated CO2 on Berry Development and Bunch Structure of Vitis vinifera L. cvs. Riesling and Cabernet Sauvignon

Carbon dioxide (CO2) as one of the main factors driving climate change is known to increase grapevine growth and yield and could, therefore, have an impact on the fruit quality of vines. This study reports the effects of elevated CO2 (eCO2) on berry development and bunch structure of two grapevine cultivars (Vitis vinifera L. cvs. Riesling and Cabernet Sauvignon) within the VineyardFACE (Free-Air Carbon Dioxide enrichment) experiment, using must analysis and non-invasive fluorescence sensor technology. Berry development was examined on five dates over three consecutive years by analyzing total soluble solids (TSS), pH, total acidity, organic acids, nutrition status, and non-invasive Multiplex measurements. Before harvest, secondary bunches were collected to examine bunch and berry parameters. Results showed that eCO2 had little impact on berry composition of Riesling and Cabernet Sauvignon during berry development, which could be related to bunch structure or single berry weight within single seasons. Elevated CO2 (eCO2) did not result in modified TSS accumulation during ripening but was directly related to the chlorophyll index SFR_R. Higher single berry weights (SBW), higher malic acid (MA), and lower tartaric acid (TAA) were examined at some stages during development of berries under eCO2 levels. Our study provides evidence that eCO2 did alter some bunch and berry parameters without a negative impact on fruit quality.

“…Even under low g s at 11:00, the higher VPD caused increased E. High values of VPD (1.5 kPa) affect the leaf gas exchange. Higher air temperature and VPD negatively affect CO 2 assimilation due to stomatal closure (Han et al 2012;Niu et al 2012;Tretiach et al 2012). G. soja has lower resistance and higher transpiration; thus having the ability to cope with high temperatures.…”

The diurnal variations of photosynthesis of three dominant species, including Glycine soja, Phragmites australis, and Cynanchum chinensis, in the Yellow River Delta in China have been studied under the same natural conditions using a Li-6400 portable photosynthesis system. The results showed that the curves of diurnal variations of net photosynthetic rate (P N ) of the three plants were different. The diurnal variation of P N on C. chinensis was a midday depression pattern and had two peaks. However, P N of G. soja and P. australis showed single-peak curves. The transpiration rate (E) of G. soja was significantly higher than that of P. australis and C. chinensis, both showed single-peak curves. In general, the diurnal course of stomatal conductance (g s ) followed the same pattern of P N . A similar diurnal pattern of intercellular CO 2 concentration (C i ), vapor pressure deficit (VPD), and water use efficiency (WUE) was observed among different species. VPD showed single-peak curves, while WUE was characterized by double-peak curves, which was contrary to C i . Linear correlations among photosynthetic variables and key environmental factors indicate high positive correlations between P N and E, P N and photosynthetic active radiation, P N and leaf temperature (T leaf ), P N and VPD, and between P N and g s except C. chinensis. Negative correlations among P N and relative humidity, P N and C i were found. The irradiance response curves derived from the leaves were substantially affected by different species. C. chinensis showed highest apparent quantum efficiency, followed by P. australis and G. soja, while apparent dark respiration (R d ), convexity (k), light saturation point, and maximum gross CO 2 assimilation rate (P max ) of G. soja were higher than those of P. australis and C. chinensis. The irradiance response curve of P N and WUE of different plant species followed the same order: G. soja . C. chinensis . P. australis. They were both higher than most of other species. It was concluded that plant species adapting to the saline -alkaline habitat showed higher photosynthesis. In addition, G. soja is also effective to improve saline -alkaline soil quality.
