“…The average crop yields were (7 517 and 6 597) kg·ha -1 , respectively, with and without cattle manure addition (table IV). Hernandez et al [20] reported that, for a fruit yield of 10 t·ha -1 of ripe figs and (table VII). Proebsting and Warner [22], studying Adriatic and Calimyrna fig varieties, evaluated the N, P, K, Ca and Mg leaf contents between April and September; they observed that the N and P contents decreased with plant development; the K contents showed an unusual tendency, that is, there was a great increase in leaf content between April and June, decreasing thereafter until September; the Ca and Mg contents increased during the period April to September.…”

Preliminary report on yield productivity and mineral composition of the fig tree as a function of boron and cattle manure fertilization in Brazil.Abstract --Introduction. Information correlating leaf nutrient contents to fig tree yield is still rare in Brazil. The objective of our research was to evaluate the effect of fertilization with boron and cattle manure on fig tree productivity and the leaf and fruit nutrient contents, and to estimate the extraction of nutrients by the crop. Materials and methods. The treatments consisted of five boric acid levels [(0, 20, 40, 60 and 100) g per plant] combined with two levels of cattle manure [(0 and 10) kg per plant]. The experimental design was in randomized blocks in a split-plot scheme with four replicates. The cattle manure levels constituted the plots, and the boron levels the subplots. We studied tree productivity, macronutrient and micronutrient leaf and fruit contents, amounts of nutrients extracted per ha and per crop yield, and fig tree leaf and fruit dry matter nutrient contents as a function of sampling dates. Results. Fruit yield productivity, average fruit weight and number of fruits per tree were not affected by B fertilization but they were by cattle manure levels, which increased Résumé --Introduction. Les informations sur le lien entre la teneur en éléments nutritifs des feuilles et la productivité du figuier manquent encore au Brésil. L'objectif de nos recherches a été d'évaluer l'effet de la fertilisation avec du bore et du fumier de bovins sur la productivité du figuier, la teneur en éléments nutritifs des feuilles et d'estimer l'exportation des éléments minéraux dans les fruits récoltés. Matériel et méthodes. Les traitements ont été constitués par cinq niveaux d'acide borique [(0, 20, 40, 60 et 100) g par plant] combinés à deux doses de fumier de bovins [(0, 10) kg par plant]. Le dispositif expérimental a été celui de blocs randomisés selon un schéma de split-plot à quatre réplications. Les doses de fumier ont constitué les traitements et les niveaux de bore les sous-traitements. Nous avons étudié la productivité des arbres en fruits, la teneur des feuilles et des fruits en macro et microéléments, la quantité d'éléments minéraux extraite par ha et par récolte, la teneur minérale de la matière sèche des feuilles et des fruits en fonction des dates de prélèvement. Résultats. La productivité, le poids moyen des fruits et le nombre de fruits par arbre n'ont pas été affectés par la fertilisation en bore, mais ces paramètres ont varié avec les doses de fumier, qui ont amélioré le rendement du figuier. La teneur des feuilles et fruits en macro et micro éléments sont discutés par rapport aux résultats obtenus au Brésil déjà publiés. Les doses de fumier n'ont pas affecté de manière significative la quantité d'éléments extraits à partir de la récolte de figues vertes. Les teneurs des feuilles en Mn, Zn et B et l'extraction par le fruit du Mn et du B ont augmenté linéairement avec les différents niveaux d'acide borique. Le contenu en éléments minéraux des fe...

“…[20], avaliando plantas com 12 ramos, na terceira colheita de frutos maduros, observaram médias de comprimento de frutos variando de 42,9 a 52,9 mm e diâmetro de 39,8 a 47 mm, valores bem inferiores ao presente trabalho e aos relatados por PEREIRA [35], que descreveu frutos com comprimento de 75 mm. Isto se deve ao fato de os estudos terem sido realizados em condições edafoclimáticas diferentes, tendo a planta um comportamento característico para cada região.…”

A figueira (Ficus carica L.) pertence à família das moráceas e é originária da Ásia Menor e Síria, de onde se dispersou posteriormente pelos países da Bacia Mediterrânea [31].Atualmente, tem sido introduzido no norte de Minas Gerais o cultivo da figueira. Nessa região, além da possibilidade de se obter safras com produtividade superior às das áreas tradicionais, é possível obter safras extemporâneas, como ocorre em outras localidades de condições climáticas semelhantes. Entretanto, tambem é importante a qualidade dos frutos produzidos no norte de Minas Gerais, pois cada As polyphenoloxidase and peroxidase activity was decreasing, polygalacturonase activity increased throughout the development of the fruits. The fruits reached harvest point for industry and in natura consumption at 30 and 75 days from the differentiation of the buds in syconium, respectively. A significant increase took place in the contents of total soluble solids, total soluble and reducing sugars during the development of the fruit. Both pH and TTA ranged very little during fruit development. The average diameter of the fruits was always inferior to the average length, reaching 51.99 mm and 59.18 mm, respectively at 75 days. The average weight of 53.23 g was reached at 75 days. Predominating neutral sugars were galactose, arabinose and xylose whereas fucose, mannose and glucose and rhamnose were those present in smaller amount in the cell wall during the different developmental stages of the fruits. With the maturation of the fruits, there was a reduction of the chief components of pectic polysaccharides (galactose, arabinose and rhamnose), whilst the components of the hemicellulose fraction (xylose, glucose and mannose) tended to increase. Cellulose solubilization and fall in the contents of hemicellulose took place from 60 days when the fruit already in the physiological maturity, starts softening process, as related with pectin solubilization by the higher activity of the pectinnemethylesterase and polygalacturonase enzymes.
