1. Effects of Citrus Sudden Death Disease on Fatty Acid Profile of Orange Tree Bark
Citrus sudden death (CSD) is a disease that has affected millions of orange trees in Brazil, leading to economic losses in the order of billions of US dollars. This article examines the effects of CSD on the fatty acid composition of triacylglycerides (TAG) extracted from rootstock and scion bark. The fatty acid profile determined by gas chromatography showe

2. Use of mineral particle film to protect ‘Okitsu’ tangerine and ‘Valencia’ orange against Anastrepha fraterculus and the effect on fruit quality
ABSTRACT The particle film technology has been reported as a promising tool in pest control. The objective of this work was to evaluate the efficiency of kaolin-based products against the oviposition of South American fruit fly, Anastrepha fraterculus (Dip.:Tephritidae), and its effect on the quality of citrus fruits. The experiment was conducted in orchards

3. Evaluation of Lignins of Trunk and Roots from Citrus sinensis L. Osbeck: A Large Available Brazilian Biomass
Citrus biomass is a source of biobased products and presents extensive chemical diversity. Among the structural macromolecules, lignins have been used in resins, bioplastics, and nanoencapsulation. Brazil has a large source of lignins, which are orange trees removed from groves that need to be renewed. However, the knowledge about these lignins is limited an

4. Response of grey slug to entomopathogenic nematodes
ABSTRACT Biological control using entomopathogenic nematodes (EPNs) is known as an ecofriendly strategy in integrated pest management. The terrestrial slug Parmacella ibera is a major pest of vegetables and citrus trees in north of Iran. The heavy costs and environmental concerns of synthetic molluscicides led the study to use EPNs, against the slug P. ibera

5. Compatibility and horticultural performance of Pera sweet orange clones grafted to Swingle citrumelo rootstock
ABSTRACT Despite its interesting agricultural traits, Swingle citrumelo (Citrus paradisi Macfad. ‘Duncan’ × Poncirus trifoliata L. Raf.) rootstock exhibits severe incompatibility when grafted with Pera sweet orange [Citrus sinensis (L.) Osb.] scions, and this fact limits its use for propagation purposes. Nonetheless, the existence of certain Pera sweet

8. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

10. Dwarfing-canopy and rootstock cultivars for fruit trees
Resumo Como as plantas frutíferas apresentam em geral porte elevado, a obtenção de plantas de porte reduzido, ou até anãs, é de grande interesse na fruticultura. Nesta revisão são comentadas algumas das principais plantas frutíferas de clima tropical, subtropical ou temperado que têm variedades de porte reduzido, ou mesmo anãs. As causas do nanis

12. Soil quality indicators under management systems in a Quilombola community in the Brazilian Cerrado
ABSTRACT: Soil management systems exert different effects on soil attributes, especially on the organic matter content, and, consequently, the soil aggregation. The aim of this study was to evaluate the impact of different land uses practiced by quilombola family farmers on water stable aggregates, glomalin and organic carbon in soil aggregates. Soil samples
