Introduction & Aim: The aim of this study was evaluating effect of methanol and ethanol foliar application as a new and safe technology in plant production on lemon balm’s (Melissa officinalis L.) volatile oil components. Experimental: Experimental carried out based on a Randomized Complete Block Design (RCBD) with fifteen treatments and three replications in the experimental field of...

Production, transformation and essential oils composition of leaves and stems of lemon verbena [Aloysia triphylla (L’Herit.) Britton] grown in Portugal. More than seventy compounds, including 13 n-alkanes, were identified by GC and GC-MS in essential oils from leaves of lemon verbena [Aloysia triphylla (L’Herit.) Britton] plants harvested and analysed with intervals of around two months during ...

Oils extracted from Cymbopogon citratus, Lantana camara, Artemisia camphorata, and Imperata cylindrica plants were used as potential insecticides against the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae). The phytochemical composition of isolated oils was identified by gas chromatograph-mass spectrometry (GC-MS). Oil contact toxicities evaluated adults S. oryzae. activities ac...

application of organic fertilizers increases quality and yields in the sustainable crop production and considerably replaces or reduces chemical fertilizers. in order to study the effects of different manure and vermicompost rates on yield and essential oil contents of dragonhead, an experiment was conducted as a randomized complete blocks design with eight treatments and three replications in ...

Geranyl diphosphate (GPP), the precursor of most monoterpenes, is synthesized in plastids from dimethylallyl diphosphate and isopentenyl diphosphate by GPP synthases (GPPSs). In heterodimeric GPPSs, a non-catalytic small subunit (GPPS-SSU) interacts with a catalytic large subunit, such as geranylgeranyl diphosphate synthase, and determines its product specificity. Here, snapdragon (Antirrhinum ...
