  Background: Borage (Borago officinalis L.) is a valuable medicinal plant with a high content of gamma linolenic acid. It has an important place in Iranian traditional medicine. Although the aerial parts of this plant are extensively used in treatment of diseases, detailed knowledge of the active constituent changes in these parts is not readily available. In addition the most data that has be...

in order to study the effect of water deficit stress at different growth stages on yield and seed oil quality of rapeseed cultivars, a field experiment was conducted as split-plot in a randomized complete block design arrangement with three replications in 2009-2010 growing seasons in abarkouh in iran. four levels of irrigation were located in the main plot including, (i1) normal irrigation bas...

Rice (Oryza sativa) is the primary food source for more than one-half of the world's population. Because rice cultivation is dependent on water availability, drought during flowering severely affects grain yield. Here, we show that the function of a drought-inducible receptor-like cytoplasmic kinase, named GROWTH UNDER DROUGHT KINASE (GUDK), is required for grain yield under drought and well-wa...

The transcription factor HAHB10 belongs to the sunflower (Helianthus annuus) HD-Zip II subfamily and it has been previously associated with the induction of flowering. In this study it is shown that HAHB10 is expressed in sunflower leaves throughout the vegetative stage and in stamens during the reproductive stage. In short-day inductive conditions the expression of this gene is induced in shoo...

abstract supplementary irrigation for suitable crops production in most area of iran is necessary. in order to study supplementary irrigation effects on yield and yield components of three lentil (lens culinaris medik.) cultivars, an experiment was carried out as split block based on randomized complete block design with three replications at research field, college of agriculture, ferdowsi uni...

The range grazing and distance walked for diet selection and nutritive value were studied in close and open range systems at the flowering and seed setting stages during the September and November 2009 respectively in El-khuwei locality (El Rosa). A completely randomized design was used (CRD). Sampling was done by two stage flowering and seed sating stage under protected and open range systems ...
