The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of six Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected between June and Aug...

in order to evaluate the effects of planting date and corm density on yield and some other traits of saffron under climatic conditions of malayer in the west of iran, an experiment was conducted using split plots based on randomized complete blocks design with four replications. different planting dates (15th july, 15th august and 15th september) were allocated in the main plots and different c...

in order to investigate the response of coneflower to applying chemical fertilizer and incorporation with municipal solid waste compost (mswc), a pot experiment was conducted as completely randomized design with six treatments included: control (without applying chemical fertilizer and compost), chemical fertilizer (150 kg n, 120 kg p2o5 and 250 kg k2o per hectare from urea, triple super phosph...

this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...

To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...

Pistachio is one of the most important horticultural crops in Iran.  There is a unique role for amino acids in the plant response to stressful conditions, and special physiological role for Arginine (Arg) compared to other amino acids.  The effects of this compound were investigated on vegetative and reproductive characters of bearing pistachio trees of ‘Ahmad-Aghaei’. The experiments were done...
