Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth and development. Each species o...
1- introduction crop development is qualitative changes planned that led the plant to ripening. factors such as water available, nitrogen and photosynthetic materials are affected growth and development. under irrigated conditions expected that all of factors except climate elements be controlled. thus, only climate elements able to change of plant growth and development and under these conditi...

انگور شاهانی vitis vinifera l.(shahani grape) به خانواده vitaceae تعلق دارد. این میوه به دلیل داشتن ترکیبات فنولی در پیشگیری از بسیاری بیماری ها مثل انواع سرطان و عفونت ها مصرف می شود. این پژوهش با هدف بررسی ساختارهای تشریحی-تکوینی خواص ضد میکروبی، ضد جهشی و آنتی اکسیدانی گیاه انگور شاهانی انجام شد. در این تحقیق از روش های متداول سلول-بافت شناسی، تهیه برش های دستی، میکروتومی، رنگ آمیزی های لازم...
Successful anther/microspore culture largely depends on the use of microspores at appropriate developmental stages at the time of culture, which can be specific for each plant species and genotype. This study was carried out to determine the correlation between morphological characteristics, namely floral bud (FB) length and width and anther length, and specific microspore developmental stages ...
background essential oils (eos) possess antibacterial properties and represent a natural source to treat infections and prevent food spoilage. their chemical composition might be affected by the environmental condition and the developmental growth stages of the plant. objectives the current study aimed to determine the variations in chemical compositions and antimicrobial activities of the eos ...
in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...
Plant roots constantly secrete compounds into the soil to interact with neighboring organisms presumably to gain certain functional advantages at different stages of development. Accordingly, it has been hypothesized that the phytochemical composition present in the root exudates changes over the course of the lifespan of a plant. Here, root exudates of in vitro grown Arabidopsis plants were co...
Plant height, which shows dynamic development and heterosis, is a major trait affecting plant architecture and has an indirect influence on economic yield related to biological yield in cotton. In the present study, we carried out dynamic analysis for plant height and its heterosis by quantitative trait loci (QTL) mapping at multiple developmental stages using two recombinant inbred lines (RILs...
