“…The means found for Fv/Fm (0.689 to 0.788) were consistent with other Fv/Fm results reported for arboreal species. Ammar et al (2020) found means ranging from 0.493 to 0.741 in an experiment in Tunisia, with the lowest means found in summer and early autumn when temperatures and light incidence were higher. Similarly, Gomes et al (2008) found Fv/Fm means close to 0.741 in a study characterizing the photosynthetic performance of fig trees in the state of Espirito Santo, Brazil; the authors noted that other fruit tree species grown in the same area, such as coconut and mango trees, had Fv/Fm means of 0.74 and 0.76, respectively, which are similar to the results found in the present study.…”

“…The means of stomatal conductance (gs) varied from 0.280 to 0.584 mol m -2 s -1 , which are similar to results reported in the literature. Ammar et al (2020) evaluated physiological dynamics in 5-year-old fig trees over 259 days in Tunisia and found maximum means of 0.370 and 0.435 mol m -2 s -1 during late spring when temperatures ranged from 28 to 31 °C; however, the lowest means (below 0.100 mol m -2 s -1 ) were found during summer when temperatures were higher than 35 °C. Can et al (2008) and Ammar et al (2020) reported that the maximum gs was found when daytime temperatures were around 30 to 32 °C, as at these temperatures, water viscosity decreases and mesophyll conductance increases, increasing guard cell turgor pressure and stomatal opening.…”

This work aimed to evaluate changes in gas exchanges and chlorophyll a fluorescence in fig plants due to the film formed on the leaf surface by Bordeaux mixture applied to control rust. The experiment was conducted in an orchard with 7-month-old fig trees of the cultivar Roxo de Valinhos, in April 2020. A completely randomized experimental design with four replications was used, consisting of two treatments (with and without application of Bordeaux mixture), evaluating leaves in three different parts of the branch (apical, middle, and basal) in five evaluations. The evaluated gas exchange parameters were: carbon, leaf temperature, transpiration, stomatal conductance, and photosynthesis. The evaluated chlorophyll fluorescence parameters were: maximum and effective quantum yield of the photosystem, electron transport rate, photochemical and non-photochemical quenching, and leaf area. The film formed by Bordeaux mixture application did not affect the photochemical phases of photosynthesis and chlorophyll a fluorescence. The leaf position on the branch affected internal CO2 concentration and net CO2 assimilation over time. Leaves in the middle part of the branch presented larger leaf areas than those in the apical and basal parts. Keywords: Ficus Carica L.; chlorophyll a; rust; leaf area. A película formada pela calda bordalesa na superfície foliar das figueiras interfere nos processos fotoquímicos? RESUMO: O objetivo desse trabalho foi avaliar se a camada formada pela solução da calda bordalesa na superfície foliar altera as características das trocas gasosas, bem como a Fluorescência da clorofila A, quando aplicada no combate a ferrugem. O delineamento experimental utilizado foi o inteiramente casualizado com 2 tratamentos (com e sem calda bordalesa) com folhas em 3 partes distintas do ramo da figueira (apical, mediana e basal), sendo feitas 5 avaliações, com 4 repetições, em um pomar de 7 meses de idade da cultivar Roxo de Valinhos, no mês de abril de 2020. As avaliações das trocas gasosas foram referentes a: variação do carbono, temperatura da folha, transpiração, condutância estomática e fotossíntese. As avaliações da fluorescência da clorofila A, foram referentes a: rendimento quântico máximo e efetivo do fotossistema, taxa de transporte de elétrons, dissipação fotoquímica e não fotoquímica e área foliar. A película formada pela aplicação da calda bordalesa não interferiu nas etapas fotoquímicas da fotossíntese e na fluorescência da clorofila A. A Concentração interna, e a assimilação líquida do CO2 foram influenciadas pela posição da folha no ramo ao longo do tempo. As folhas da parte mediana do ramo apresentam a maior área, em detrimento das partes apical e basal. Palavras-chave: Ficus Carica L.; clorofila A; ferrugem; área foliar.

“…Native to the Middle East, it was domesticated in the Mediterranean region, where it was among the first crops to be cultivated in association with grape and olive trees, marking the beginning of horticulture in this region [39]. F. carica L. cultivation has expanded mostly due to its adaptability to different environmental conditions, as well as the economic importance of its fruit, which provides an excellent source of nutrients and antioxidants [40][41][42]. This study aimed to determine whether climate change and pest invasion affect fig tree yield in Northeast Algeria (Bejaïa province), where figs are renowned to be of high quality at both the national and international level.…”

Fig cultivation has long been an agricultural tradition in the Mediterranean region, providing economic and social benefits to local communities. Understanding fig tree yield response to the rapid invasions of fig pests and shifts in climatic conditions is essential for developing appropriate sustainable agricultural strategies. In this context, we investigate whether rapid changes in climate and pest invasions have had a combined effect on fig (Ficus carica L.) tree yield. We used data collected over 10 years in Bejaïa province, Algeria, and conducted a regression analysis to investigate the relationship between fig tree yield and two key factors. Results revealed a significant warming trend (0.057 °C yr−1), and a decrease in precipitation (−27.1 mm yr−1), in the region. Multiple pests, including pathogenic fungi (Diaporthe cinerascens, Fusarium spp.) and ravaging bark beetles (Hypocryphalus scabricollis), have spread in the region. Fig tree yield declined by 25% during the study period and was affected by both factors. Our findings provide valuable insights that can aid farmers and practitioners in mitigating risks that arise from the combined effects of climate change and pest invasions, thereby promoting sustainable farming practices.

“…Although fig can easily adapt to climatic conditions, its growth and development vary in different environments (AMMAR et al, 2020). Thus, crop management may improve the plant vegetative growth, productivity, and fruit quality, in addition to reducing the attack of phytopathogens and maximizing the effect of phytosanitary treatments.…”

Fig (Ficus carica L.) is widely accepted due to its organoleptic and pharmacological properties. Search for innovations to improve the crop management has increased to reduce environmental impacts and improve the organoleptic quality and food safety of the fruits. Thus, this study aimed to evaluate the influence of fertilization methods and plant training systems on the production and physicochemical traits of fig. The experiment was carried out in a randomized complete block design in a 5 × 4 factorial scheme, with three blocks and three plants per plot. The factors corresponded to five fertilizers (chemical, cattle manure, sheep manure, poultry litter, and organic compost) and four training systems (two branches, three branches, four branches, and espalier). Results showed that, when using chemical fertilizer and poultry litter, plants showed similar productivity and number of fruits, which had similar firmness, length, and peel color (L and °h). The highest production and number of immature fruits were obtained using cattle manure. Soluble solids content and soluble solids content/ titratable acidity ratio were higher in fruits from plants fertilized with cattle manure, sheep manure, and organic compost. On the other hand, plants trained with three and four branches or in espalier produced fruits with the highest soluble solids content and weight. Also, heavier fruits were obtained using chemical fertilization and conducting plants with two, three, and four branches.
