“…According to Asthir (2015), the stress suffered by exposure to high temperatures can decrease the plant metabolism by interfering with electron transport and reducing the effectiveness of photosynthesis. Also, Oliveira et al (2012) reinforce that high exposure to the sun can affect metabolism, reducing coffee yield, predisposing the plant to the manifestation of diseases such as Cercosporiosis (Cercospora coffeicola).This result confirms the importance of temperature in the phenological cycle of coffee and its interference in each stage (Gaspari-Pezzopane et al, 2009). According to Rena and Barros (2004), it is common for up to four blooms to occur in most coffee plantations in Brazil, which results in splitting the fruit development that happens in a non-simultaneous way Rena,1999).…”

“…Main flowerings are generally well defined and occur due to severe water deficiency in the bud resting phase, followed by rainfall and a drop in average temperature. Studies by Gaspari-Pezzopane et al (2009) indicate that the absence of a marked water deficit may be one of the responsible factors for the remaining flowering in the reproductive period.…”

Aiming to determine the interaction between climatic factors, flowering and yield of dry arabica coffee in municipalities in the regions of Southern Minas Gerais and Alto Paranaíba, both in the State of Minas Gerais, this study considered data from the harvest years 2008/2009 to 2017/2018, and climatic data analyzed according to the coffee phenological cycle. The determination of significant variables used the Stepwise method and the Akaike Information Criterion (AIC). The association of yield with climatic variables used a generalized linear model with gamma distribution and logarithmic function. Average flowering (20% to 50% of flowers per branch) used a logistic regression model. The productive variability of arabica coffee showed an association with the biennial cycle, the occurrence of medium and main flowering, flowering period and rains in bean formation. The occurrence of average flowering and the frequency of rainfall during bean formation enhanced coffee yield, at the same time as the increment in maximum temperature in vegetative bud formation reduced flowering and yield.

“…Segundo GASPARI-PEZZOPANE et al (2009) Devido à grande importância econômica do maracujazeiro-azedo, este estudo teve como objetivo, realizar a caracterização da fenologia reprodutiva, elaborar uma escala ao atribuir notas a cada estádio fenológico reprodutivo e avaliar os atributos: taxa e pico de florescimento, além da taxa de frutificação.…”

The objective of this study was to determine the harvest period of coffee fruits based on the relationship between agrometeorological parameters and sucrose accumulation in the seeds. Over the crop years 2004/2005 and 2006/2007, from 150 days after flowering (DAF) onwards, samples of 50 fruits of cultivars Mundo Novo IAC 376-4, Obatã IAC 1669-20 and Catuaí Vermelho IAC 144 were collected from coffee trees located in Campinas, Brazil. The endosperm of the fruits was freeze-dried, ground and analyzed for sucrose content by high-performance liquid chromatography. A weather station provided data to calculate the accumulated growing degree-day (GDD) units, and the reference (ET(o)) and actual (ET(r)) evapotranspiration rates. The results showed that the highest rates of sucrose accumulation occurred at the transition from the cane-green to the cherry phenological stage. Models for the estimation of sucrose content during maturation based on meteorological variables exhibited similar or better performance than the DAF variable, with better results for the variables GDD and ET(o). The Mundo Novo cultivar reached the highest sucrose level in the endosperm after 2,790 GDD, while cultivar Catuaí attained its maximum sucrose concentration after the accumulated evapotranspiration rate has reached a value of 870 mm. As for cultivar Obatã, the maximum sucrose concentration was predicted with the same degree of accuracy using any of the parameters investigated. For the Obatã cultivar, the values of the variables calculated for the maximum sucrose concentration to be reached were 249 DAF, 3,090 GDD, 1,020 ET(o) and 900 ET(r).
