ABSTRACT For the Caatinga passion fruit (Passiflora cincinnata Mast.), there are no indications of varieties specific for the Brazilian Savanna conditions, as well as conduction techniques that make it possible to express a greater yield potential. This study aimed to evaluate the yield and quality of CPEF2220 and CBAF2334 populations in espalier and trellis conduction systems. A completely randomized design was used, in a 2 x 2 factorial arrangement, with three replications of four plants per plot. The fruit yield and physical characteristics were evaluated throughout the production cycle. The average yield was 8.0 kg plant-1 (3.5-14.9 kg plant-1) and the average number of fruits per plant was 139.1 (55.8-283.5), with average pulp yield of 29 %. There was a tendency to increase the number and yield of fruits for the CPEF2220 population conducted in the espalier system. The plant survival rate was 41 % (CPEF2220) and 87.5 % (CBAF2334), with a higher adaptation to the Brazilian Savanna conditions, while the CPEF2220 population presented a higher yield potential. Reductions in mass, longitudinal and equatorial diameter and fruit shape were observed throughout the harvest, with some exceptions for the espalier system, which showed more elongated fruits. The trellis system showed a greater yield potential for the parent populations of the passion fruit BRS Sertão Forte, for the study conditions.

Abstract Eucalyptus urophylla hybrids are important raw materials for the forest industry in Brazil, and large quantities of barks are available at mill site that may be used for added-value products. The chemical composition of barks of six commercial hybrids clones of E. urophylla×E. grandis, E. urophylla×E. Camaldulensis, and undisclosed E. urophylla hybrids was studied. The hybrids had similar composition, on average (data based on oven dry bark): 16% extractives, mainly corresponding to polar compounds that are soluble in ethanol and water, 19% lignin, 47% polysaccharides, 1% suberin, and 2% ash. The polysaccharides consists mainly of cellulose as indicated by 84% of total neutral monosaccharides in the acid hydrolysate and 10% xylose. The compositions of the lipophilic extracts was determined by GC-MS before and after alkaline hydrolysis. In all the barks, fatty acids, and triterpenes (namely: betulinic and ursolic acids) were the most abundant compounds followed by smaller amounts of sterols, long-chain aliphatic alcohols, phenolic acids, and acylglycerols. The ethanol-water bark extract had a high phenolic content: total phenolics ranged 211–551 mg gallic acid equivalents (GAE) g-1 of extract, tannins 76–184 mg catechin equivalents (CE) g-1 extract, and flavonoids 98–234 mg CE g-1 of extract. The antioxidant activity corresponds to 338 mg Trolox g-1 of extract. Development of high-value products is proposed through an integrated biorefinery approach including valorisation of extractives and targeting for cellulose-based applications.

O presente trabalho teve como objetivo avaliar a resposta das espécies arbóreas Schizolobium parahyba (Vell.) Blake (guapuruvu), Mimosa scabrella Benth. (bracatinga), Peltophorum dubium (Spr.) Taubert (canafístula), Parapiptadenia rigida (Benth.) Brenan (angico-vermelho) e o híbrido Eucalyptus urophylla S.T. Blake x Eucalyptus grandis Hill ex Maiden (eucalipto) em consórcio com a cana-de-açúcar (Saccharum spp.) em dois arranjos de sistemas agroflorestais (faixa - 3x3m + 12m e linha - 6x1,5m) submetidos a extremos climáticos de geada, na região Noroeste do Rio Grande do Sul. Os danos (resistência á geada) foram avaliados segundo o sistema de notas utilizado por HIGA et al. (2000) no qual atribuiu-se uma nota de 0 a 10 conforme a intensidade do dano na planta. Para os graus de resistência à geada, adaptou-se metodologia utilizada por CARVALHO (1981), a qual também é em função da intensidade do dano na planta. Diante da condição de geada estudada, observa-se que os diferentes arranjos de sistemas agroflorestais afetam a resistência da espécie guapuruvu, sendo sensível no sistema agroflorestal faixa e moderadamente tolerante no sistema linha. Em ambos os sistemas, as espécies angico-vermelho, bracatinga e eucalipto mostram-se resistentes, enquanto que a canafístula demonstra ser tolerante.
