identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. in order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in minoodasht region in golestan province (north of iran) were evaluated. traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

the first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. hence, there are various walnut breeding programs in various areas of iran. a study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the shahroud region in 2011-2012.  the following genotypes were selected in this stu...

the oak genus (quercus l.) is one of the most important genera of beach family (fagaceae) that has ecological and economical importance. chestnutleaf oak (quercus castaneifolia c.a. mey.) is native to iran and distributed in hyrcanian forests. pure and mixed stands of this taxon have covered about 6.5 % of hyrcanian forests. this study was undertaken to evaluate the effects of ecological factor...

rapid exploratory field survey, to identify indigenous chicken ecotypes was conducted in north gondar zone of ethiopia. chicken ecotypes including necked neck, gasgie and gugut from quara, alefa and tache armacheho districts were identified, respectively. morphological variations among the three study populations and nine measurable traits were evaluated. general linear model, canonical discrim...

in order to the effects of macronutrients  and micronutrients on morphological traits and yields of rice, an examination as factorial in random complete block design and 3 replicate in galoogah region during the year of 2014 conducted. the treatments of nutrients were microelements, microelements, and the mixture of microelements, macro elements and control. the results showed the treatments ha...

The present review describes the morphological, phytochemical and pharmacologyaspects of Cinnamomum tamala (Lauraceae). The plant grows wild in the tropical and subtropical Himalayas, the Khasi hills, the nilgiri hills and at the foot of the Sikkim Himalayas. There are many plantation of this species. Used as carminative, used in colic and diarrhoea. Bark is aromatic, stimulant, antigonorrhoeic...

Background: Rosemary (Rosmarinus officinalis L.) as a member of the Lamiaceae family is a valuable aromatic and medicinal plant which is cultivated in large scale in Iran. Therefore, it is necessary to determine influence of factors affecting plant growth and drug metabolite production. Objectives: This experiment was carried out to evaluate the effects of bio-stimulators compounds on growth a...
