Abstract Critical for conserving endangered orchids is identifying their pollinators and distribution. Caladenia xanthochila an orchid that has floral traits characteristic of pollination by food foraging insects. We identified the pollinator(s), mechanisms attraction presence at natural, existing potential translocation sites. Furthermore, we quantified success sites investigated effect rainfa...

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...

abstract cumin (cuminum cyminum) is one of the most important medicinal plants in iranian dry region. in order to study the effects of irrigation times and salinity stress on yield and yield components of cumin, an experiment was conducted at the research farm ferdowsi university of mashhad in 2009. factors including irrigation times (1: one time irrigation, 2: two times irrigation 3: three tim...

the present study evaluated the effects of different dosages herbicides oxyfluorfen and trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. in this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

plant growth regulators (pgrs) are widely used for lodging control in winter wheat (triticum aestivum l.) grown at high n rates. although the introduction of semi-dwarf wheat cultivars had largely solved the problem of lodging, evidence was already accumu-lating that the timely application of a growth retardant such as chlormequat (ccc) or ethephon could increase the grain yield of wheat, by th...

background & aim: the genus satureja belonging to the family of lamiaceae and consists of over 235 different species throughout the world. fourteen species grow naturally in iran of which eleven species are endemic. different species of satureja are used in food, healthy, cosmetic and medical industry. this reseach has been carried due to selection and introduction of suitable germplasm in ...

Abstract The post-harvest processing of strawberries generates considerable amounts by-products that consist the inedible parts fruit (sepal, calyx, stem, and non-marketable portion fruit), which is an environmental problem for local producers industries. This study aimed to revalue these kinds tissues through identifying quantifying genotype influence on total phenolic content, profile, antiox...

Abstract Arabidopsis sepals coordinate flower opening in the morning as ambient temperature rises; however, underlying molecular mechanisms are poorly understood. Mutation of one heat shock protein encoding gene, HSP70-16 , impaired sepal stress responses (HSR), disrupting lipid metabolism, especially cuticular lipids, leading to abnormal opening. To further explore, what extent, lipids play ro...

the aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of romanian simmental dairy cattle. for the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
