Evaluation of the incidence of the leaf spot disease caused by the biotrophic pathogen Fusicladium oleagineum on two olive cultivars (Olea europaea L.) was carried out during six years (2009/2015) in groves located at Touiref (North West of Tunisia). The studies focused on Meski and Chetoui cultivars. The evaluated foliar incidence of disease was analyzed in relationship with some factors. Dise...

The aqueous extracts of sweet basil (Ocimum basilicum L.), tarragon (Artemisia dracunculus L.), fennel (Foeniculum vulgare Miller), olive (Olea europaea L.), sage (Salvia officinalis L.), thyme (Thymus vulgaris L.), wild thyme (T. serpyllum L.), tea (Camellia sinensis (L.) Kuntze), and verbena (Verbena officinalis L.) were investigated for polyphenol, tannins, antocyanins and flavonoids. Among ...

An investigation to optimize the extraction yield and the radical scavenging activity from the agricultural by-product olive tree wood (Olea europaea L., cultivar Picual) using six different extraction protocols was carried out. Four olive wood samples from different geographical origin, and harvesting time have been used for comparison purposes. Among the fifty olive wood extracts obtained in ...

Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...

A oliveira (Olea europaea L.) é uma planta frutífera, nativa das regiões tropicais e temperadas mais antigas cultivadas. O uso de extratos vegetais conhecida atividade antimicrobiana podem adquirir significado nos tratamentos terapêuticos. objetivo do trabalho avaliar a antifúngica dos resíduos da indústria Oliveiras (bagaço) na variedade Picual partes vegetativas cultivares variedades Arbequin...

Recent evidence indicates that fruit size has evolved according to dispersers' size. This is hypothesized to result from a balance between factors favouring large seeds and dispersers setting the maximum fruit size. This hypothesis assumes that (1) the size of fruits that can be consumed by dispersers is limited, (2) fruit and seed size are positively correlated, and (3) the result of multiple ...

The polyphenolic distribution of Vitis vinifera seeds (GSE), Citrus spp. fruits (CE) and Olea europaea L. leaves (OL) extracts were characterized and quantified by HPLC methods. Radioprotective effects of these extracts and the reference flavonoids diosmin and rutin, widely used as pharmaceuticals, were determined by using the micronucleus test for anticlastogenic activity, evaluating the reduc...

Pseudomonas fluorescens strain PICF7 is a native endophyte of olive roots. Previous studies have shown this motile, Gram-negative, non-sporulating bacterium is an effective biocontrol agent against the soil-borne fungus Verticillium dahliae, the causal agent of one of the most devastating diseases for olive (Olea europaea L.) cultivation. Here, we announce and describe the complete genome seque...

Maslina (Olea europaea L.) je važna kultura koja se uzgaja u mediteranskom dijelu Republike Hrvatske. U posljednje vrijeme gljivične bolesti maslina predstavljaju sve veći izazov za proizvođače. Kao najčešća mjera suzbijanju primjenjuju kemijska sredstva zaštitu bilja. Međutim, ispoljavaju vrlo štetan utjecaj na okoliš i zdravlje ljudi životinja ne samo da suzbijaju štetne organizme već čine št...

This study was conducted to examine the ameliorative effects of foliar application some micro-algal (Chlorella vulgaris and Spirulina platensis) medicinal plant leaves (Salix alba, Psidium guajava, Olea europaea) extracts on Phaseolus (Bean) under salinity stress. On a loamy soil, pots trial carried out bean plants grown Growth characteristics, pigments, osmolytes, total phenol, antioxidant enz...
