The olive tree (Olea europaea L.) is among the oldest and most widespread crops in Mediterranean basin. Portugal third producer European Union, Trás-os-Montes region, located northeastern Portugal, second Portuguese producing region. moth, Prays oleae (Bernard) (Lepidoptera: Praydidae) a key pest Trás-os-Montes. This natural host/prey of several organisms which include larvae generalist special...

Oleuropein (OE), the main polyphenol in olive leaf extract, is likely to decompose into hydroxytyrosol (HT) and elenolic acid under the action of light, acid, base, high temperature. In the enzymatic process, the content of OE in olive leaf extract and enzyme are key factors that affect the yield of HT. A selective enzyme was screened from among 10 enzymes with a high OE degradation rate. A sin...

This research is a double blinded clinical study that tries to assay the thrapeutical effects of olive leaf extract on the oral minor aphthous ulcers in comparison with dexametasone mouth wash. The statistical society of the study was 80 patients which were equally divided into 2 groups. One group received olive leaf extract and the other group received dexametasone mouth wash (elixir 0.1%). Th...

the cotton leaf roller moth, haritalodes derogata (fabricius, 1775) (lepidoptera: crambidae) was collected on two kinds of flowering shrubs, hibiscus syriacus l. and hibiscus mutabilis l., in rasht, guilan province, during august 2013. this species represents a generic new record for the fauna of iran. a brief description of the species is provided to facilitate the identification.

abstract- olive (olea europaea l.) is one of the most valuable and widespread fruit trees in iran. salt stress-induced changes in membrane stability, photosynthesis and antioxidant enzyme activity were examined on four olive cultivars (dakal, shiraz, zard and amigdalifolia) by emphasizing the correlation between measured parameters and ion (k+, na+) accumulation. plants were subjected to four s...

Olive (Olea europaea L.) is an important source of edible oil which was originated in Near-East region. In this study, two cDNA libraries were constructed from young olive leaves and immature olive fruits for generation of ESTs to discover the novel genes and search the function of unknown genes of olive. The randomly selected 3840 colonies were sequenced for EST collection from both libraries....

Monitoring of diamondback moth (Plutella xylostella L) population on cabbage and Chinese cabbage over the past eight years has indicated that heavy rains from June to September limit the population of the insect. Therefore, during the dry period when diamondback moth is a serious pest, water was applied by sprinkler system placed 1.5 m over the cabbage crop rather than by traditional furrow irr...

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...
