Repensar les nostres arrels: la citricultura a Borriana [PDF]

Anuari De L'agrupaciÓ Borrianenca De Cultura Revista De Red, 2014
Si Borriana ha estat un poble prosper els darrers dos segles, li ho devem a la taronja. En canvi, la citricultura a Borriana actualment no gaudeix d’exit, a consequencia d’errades que s’han anat produint durant el temps. La perdua de rendibilitat, l’especulacio urbanistica i la devaluacio de la taronja han provocat un abandonament de terres massiu i un

Retorno econômico dos investimentos em P&D na citricultura paulista [PDF]

Revista De Economia E Sociologia Rural, 2012
O presente estudo teve como principal objetivo medir o retorno econômico dos investimentos em P&D na citricultura paulista. O Brasil é o maior exportador mundial de suco de laranja, e o estado de São Paulo responde por 98% das exportações brasileiras de suco. A metodologia utilizada foi o cálculo da produtividade total dos fatores (PTF), através do

Field resistance of orange fruit to citrus black spot and citrus canker in D-limonene synthase downregulated trees. [PDF]

Pest Manag Sci
Genetically modified (GM) sweet‐oranges with downregulated CitMTSE1 gene showed reduced citrus black spot severity and citrus canker incidence, confirming terpene modulation as a promising strategy for sustainable field citrus disease resistance. Abstract BACKGROUND Citrus black spot (CBS), caused by Phyllosticta citricarpa, and citrus canker (CC ...

Targeting ParPMC Susceptibility Hubs in Prunus: eEF1A as a Conserved Mediator of Plum Pox Virus Infection in Nicotiana benthamiana. [PDF]

Mol Plant Pathol
ParPMC interactors were screened, highlighting eEF1A proteins; co‐localization and VIGS show their role in PPV infection and sharka susceptibility. ABSTRACT Sharka, caused by Potyvirus plumpoxi (plum pox virus, PPV), is the most destructive viral disease affecting Prunus species worldwide.

Porta-enxertos utilizados na citricultura [PDF]

Ciencia Rural, 2001
A muda cítrica é o insumo mais importante na formação de um pomar. As características mais importantes da muda cítrica são a origem do enxerto e do porta-enxerto, a qualidade do sistema radicular e a sua sanidade. Os porta-enxertos são capazes de influenciar várias características horticulturais e sanitárias nas árvores e nos frutos cítricos, como ...

Sensitivity to demethylation-inhibiting fungicides and induced expression of CYP51 associated with tebuconazole resistance in Alternaria species on mandarin in Brazil. [PDF]

Pest Manag Sci
Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...

Parallel host shifts in a bacterial plant pathogen suggest independent genetic solutions. [PDF]

Mol Plant Pathol, 2023
In Xylella fastidiosa, two parallel host shifts to infect olive trees occurred in Brazil and Italy, but the lack of genetic convergence in olive‐infecting strains across the two distinct clades suggests independent genetic solutions. Abstract While there are documented host shifts in many bacterial plant pathogens, the genetic foundation of host shifts

High Environmental Irradiance Induces Anatomical and Ultrastructural Damage in Citrus Leaves. [PDF]

Physiol Plant
ABSTRACT Climate change is intensifying episodes of high irradiance and thermal stress, posing a major threat to the sustainability of citrus production. Although reflective particle films have emerged as mitigation tools, their protective effects at the anatomical and ultrastructural levels under field conditions remain insufficiently understood. Here,
