The effects of different concentrations (0, 25, 50, 75 and 100%) of aqueous leachate of Achillea biebersteinii on germination characteristics, seedling growth, photosynthetic pigments and protein contents of pepper (Capsicum annuum L.) were investigated through conducting laboratory and greenhouse experiments. Leachate of A. biebersteinii affected negatively germination percentage, germination ...

Introduction: Intraoperative electron radiation therapy (IOERT) is one of the cancer treatment techniques that delivers high doses to tumor bed during surgery. IOERT can be performed by either conventional LINACs or dedicated IORT accelerators such as LIAC (Light Intraoperative Accelerator). Two types of applicators can be used with LIAC dedicated accelerator including conventi...

Germination of tomato seeds exposed to a single, saturating irradiation from light sources of different spectral energy distribution seems to be dependent upon the photostationary P(FR)/P(R) ratio established by the irradiation. Germination of tomato seeds exposed to prolonged irradiations from the same light sources does not seem to be controlled solely by the P(FR)/P(R) ratio induced and main...

BACKGROUND AND AIMS Ecotypic differentiation has been explored in numerous plant species, but has been largely ignored in the Orchidaceae. Applying a specific germination protocol for widespread seed sources may be unreliable due to inherent physiological or genetic differences in localized populations. It is crucial to determine whether ecotypic differentiation exists for restoration and conse...

Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...

calotropis proceran (asclepidaceae) is an evergreen plant and widely distributed in hormozgan province. this plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. in this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (cucumis sativus), tomat...

the genus thymus is perennial medicinal plants belong to the lamiaceae familythat is used for different propose in pharmaceutical industry. environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. the purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...
