knowledge of environmental and ecological factors as well as growth and development pattern of fruit trees is an important task in orchard management and fruit industry. in addition, determination of growth pattern is an important aspect in the orchard management system. in this research, the total photosynthesis rate and growth pattern was measured in nine asian pear cultivars. experiment was ...

water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...

the purpose of present study was to determine the effect of different levels of balance task difficulty and visual feedback on balance in elderly women. fourteen healthy elderly women (mean age 57/65 yr) were selected voluntarily. participants were asked to stand still on a stability platform under each of two conditions (with visual feedback and without visual feedback) in three levels of diff...

to study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. the effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weigh...

this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...

introduction malachite green (mg) has been used as a food coloring agent, food additive, medical disinfectant as well as a dye in silk, wool, jute, leather, cotton, paper, and acrylic industries. it is also extensively used as a topical fungicide and ectoparasiticide in aquaculture industries throughout the world. the findings reveal that this dye has now become one of the most controversial co...

sesame is one of the most important oil crops in iran. high oil seed content makes it difficult to store for a long period of time. this study was conducted in 2012 to evaluate possible physiological and biochemical changes in seed under different storage conditions. various seed moisture content (5, 9, 13, and 17%) were evaluated under five temperatures (5, 15, 25, 35, 45) for six month. germi...

introduction the main challenge for health in twenty century was survival, but in the new century the life with a better quality is an important matter. aging is an emotion period in human life and attention to needs in this period is a social necessity. therefore, attention to the quality of life of elders is very important in the social policy. the number of the elderly is increasing across t...

zagros forests are a treasure of various valuable species of oak in iran and the world. long-term misuse in the past has caused severe degradation in the zagros forests. recently these forests have become national but misuses by local people to make living because of poverty and unemployment are continued. in order to reduce degradation and improve sustainability, ecological capability for exte...
