“…DNA methylation, the most characterized epigenetic mechanism, affects various crucial aspects of the evolutionary biology of fig trees, such as varietal and behavioral differentiation of plants under environmental pressure (Rodrigues et al, 2019b).…”

Commercial fig tree cultivation in Brazil involves a single cultivar, ‘Roxo-de-Valinhos’. The use of a single cultivar results in serious diseases and related problems. The aim of this study was to characterize fig accessions by analyzing the natural root-knot nematode and leaf rust incidence in relation to the epigenomic profile of the plant, since epigenetic variations affect plant–pathogen interactions. All plants were attacked by nematodes, indicating susceptibility; Meloidogyne incognita was the root-knot nematode species involved. Joint analysis of data showed that methylation and leaf rust incidence were correlated when observed in the same phenological phase, presenting initial evidence of the same factorial pressure loads in genotypes, suggesting similar behavior within these genotypes.

“…For soluble solids, 'Troyano', 'White Genova' and 'Roxo de Valinhos' showed the highest averages, while 'PI-189' the lowest one (Table 1). Rodrigues et al (2019b) found higher values of soluble solids contents for 'Roxo de Valinhos' (12.74 ºBrix), 'White Genova' (11.51 ºBrix), 'PI-189' (12.48 ºBrix) and 'Troyano' (13.68 ºBrix); according to them, the highest levels of soluble solids is associated with edaphic and climatic conditions of the growing regions, since high temperature leads to sweeter fig fruits.…”

Figs consumption date back to the beginnings of civilization. Currently, consumers have become more demanding about quality of fruits, and figs are then highly indicated, since it is rich in nutrients, making them a great addition to a healthy diet. Although there is only one commercial fig cultivar that is commonly grown in Brazil, different cultivars should be considered for the diversification of fig production with regards to their yield and fruit quality. This research aimed at evaluating growth, yield, physicochemical characteristics and bioactive compounds of figs grown in Brazil. Then, four cultivars (Roxo de Valinhos, White Genova, PI-189 and Troyano) were studied to determine canopy volume, productive efficiency, soluble solids - SS, pH, titratable acidity - TA, SS/TA ratio, sugars, ascorbic acid, phenolic compounds, pigments and antioxidant activity. The cv. White Genova presented the highest canopy volume, while ‘Roxo de Valinhos’, ‘PI-189’ and ‘Troyano’ performed the greatest productive efficiency. The cvs. Roxo de Valinhos, White Genova and Troyano produced fruits with higher content of SS, reducing sugars and SS/TA ratio, while the fruits of ‘PI-189’ and ‘Roxo de Valinhos’ contained the highest levels of antioxidant activity. PCA enabled to differentiate the studied cultivars, which evidenced that PI-189 was the most different of all.

“…Fig tree as a low chill fruit species has his growth and development highly dependent on the environmental factors, which mainly affects vegetative rest period and consequently, resulting in low yields (Rodrigues et al, 2019). Fig trees can grow in cold and dry climates, since they are native to the Mediterranean area, where prevails an essentially frost-free moderate temperate climate.…”

Chill hours availability influence break dormancy, sprouting and production of temperate fruits trees in different regions. However, there are few reports on the subject for fig tree. This study aimed to evaluate the effects of the accumulated chilling hours on the physiology and dormancy release of fig cultivars. Stem cuttings of five fig cultivars were collected at the end of winter over two crop cycles and exposed to 0, 40, 80, 120 and 160 accumulated chilling hours (CH) in a cold chamber (8±0.5 ºC). Physiology of fig buds was then evaluated with regards to antioxidant enzymes activity, carbohydrate and nitrogen contents. The exposure of fig stem cuttings with two buds to different accumulated CH presented physiological changes for antioxidant enzymes activity, carbohydrates and nitrogen contents and confirming that the cultivars responded differently to the climatic conditions of each crop cycle. Results detected that the lowest accumulated CH in field in 2018 (2.7 CH) enabled a greater effect of the artificial CH when compared to 2017 (19.5 CH). Each fig cultivar had a critical accumulation point. The cultivars Roxo de Valinhos and Pingo de Mel require less CH to break dormancy, while Troyano requires more CH to finish this vegetative rest period.
