Rosemary (Rosmarinus officinalis L.) is an important medicinal plant that contained a wide range of secondary metabolites such as rosmarinic acid. In this study, essential oil content and composition and rosmarinc acid were determined at three phenological stages (before flowering, full flowering and fruit set stages). Hydro distillation method was used for essential oil extraction and GC and ...

The present work aimed to improve rose flowering during Winter where most flowers are disappeared and marketing is very profitable. Pruning experiments were carried out on the essential oil yielding hybrid tea rose cultivar (Eiffel tower) at the Floriculture Experimental Farm of Agriculture Faculty, Sohag University, Egypt during two successive years of 2007/2008 and 2008/2009. Four pruning typ...

During the initial vegetative phase, the Arabidopsis shoot meristem produces leaves with associated lateral shoots at its flanks, while the later reproductive phase is characterized by the formation of flowers. The LEAFY gene is an important element of the transition from the vegetative to the reproductive phase, as LEAFY is both necessary and sufficient for the initiation of individual flowers...

the responses of isabgol (plantago ovata forsk.) to micronutrient foliar application under low irrigation condition were investigated. the experiment was carried out in agricultural research farm of zabol university, iran, during growing season of 2007-2008. the experiment was conducted in spilt plot using randomized complete block design with four replications. three irrigation regimes defined...

This study was conducted to investigate the photoperiodic flowering response of Elsholtzia angustifolia. Plants were grown under 9/15 h (day/night) (short day, SD), 16/8 (long LD), and night interruption (NI, 4 around midnight) conditions. Supplemental lighting with a light intensity µmol·m-2·s-1 applied for LD NI treatments. continuous SD conditions developed first floral bud at 5 weeks after ...

A number of Eucalyptus species exhibit precocious flowering, flowering within a year of germination and often while still exhibiting juvenile foliage. To understand the nature of precocious flowering in Eucalyptus occidentalis, partial homologues of the inflorescence meristem identity gene TERMINAL FLOWER1 and of the floral meristem identity genes LEAFY and APETALA1 (EOTFL1, EOLFY and EOAP1, re...

Background & Aim: Deanaie thyme (Thymus daenensis Celak.), a member of the Lamiaceae family.  Thymus in one of the most important medicinal and aromatic plants that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. Recent studies have showed that thyme have strong antibacterial, antifungal, spasmolytic and antioxidant acti...

This study aims to evaluate the flowering phenology of selected 95 Elepidote Rhododendron taxa. The period was assessed, distinguishing ten developmental stages. Flowering observed every three days. comparative scale prepared indicates exact succession bloom taxa lasted from end April second half June. individual cultivars ranged 2 9 weeks. time belonging same species mostly similar. term in fo...
