The influence of two carbon sources, sorbitol and sucrose on In vitro shoot proliferation and rooting of peach rootstock GF 677 was compared at 15, 30, 45 and 60 g l concentrations. The highest number of shoots per proliferated explant, usable shoots and shoots having maximum fresh weight were obtained on sorbitol at 30 g l. GF 677 does not seem to be an efficient utilizer of sucrose for In vit...

A simplified method for building three-dimensional (3D) mock-ups of peach trees is presented. The method combines partial digitizing of tree structure with reconstruction rules for non-digitized organs. Reconstruction was applied at two scales: leaves on current-year shoots (CYS) and shoots on 1-year-old shoots (OYOS). Reconstruction rules make use of allometric relationships, random sampling o...

otostegia persica (burm.) boiss. is used for the treatment of various diseases in traditional medicine. the aim of this study was to assess the effects of hydroalcoholic extract of the aerial parts of o. persica in dexamethasone (dex) induced hypertension in male wistar rats. for induction of hypertension, dex at 30 µg/kg/day was administered subcutaneously for 14 days. in a prevention study, a...

plants produce a diverse array of secondary metabolites, many of which have antimicrobial activity. otostegia persica bioss. (labiatae) grows in south east of iran. no previous investigation on antimicrobial effects of this plant has been reported. thus, the aim of this work was to examine the antimicrobial effect of o. persica extracts with different polarity on several microorganisms. aerial ...

Objective: To evaluate the hepatoprotective properties of Otostegia persica (O. persica) ethanol extract on carbon tetrachlo‌‌ride-induced liver damage in rats. Materials and Methods: Fifty adult male Wistar rats were randomly divided into five groups. Group I served as normal control and was given only olive oil intraperitoneally (i.p.). Group II, III, IV, and V were administered CCl4 mixed wi...

Prunus persica fruits were removed from 1-year-old shoots to analysis photosynthesis, chlorophyll fluorescence and genes changes in leaves to low sink demand caused by fruit removal (-fruit) during the final stage of rapid fruit growth. A decline in net photosynthesis rate was observed, accompanied with a decrease in stomatal conductance. The intercellular CO2 concentrations and leaf temperatur...

We investigated the influence of bud position, cultivar, tree age, tree carbohydrate status, sampling date, drought and light exposure on the number of leaf primordia formed in dormant vegetative peach buds (Prunus persica (L.) Batsch) relative to the number of primordia formed after bud break (neoformed). During winter dormancy, vegetative peach buds from California and Italy were dissected an...

Genetic interrelatedness among 13 strains of mycoplasmalike organisms (MLOs) from various sources was evaluated by dot hybridization and restriction fragment length polymorphism analyses using cloned DNA probes derived from Canadian peach X (CX) and western X (WX) MLOs. Dot hybridization analysis indicated that CX, WX, and clover yellow edge MLOs are closely related and form a distinct strain c...
