The effect of O(2) partial pressure on the germination and the respiration of 12 cultivated species was studied. The reciprocal of the time necessary to observe rootlet emergence in 50% of the seeds was used to approach the germination rate. The maximum germination and respiration rates were reached in most seeds at O(2) pressures close to that of air. Decreasing the O(2) pressure produced a gr...
rapeseed is one of the important oilseeds, as its oil ranks second in the world after soybean. the rapeseed cultivation has been increased recently in iran. drying of seeds to a safe moisture level is necessary for storage of oilseeds before processing. rapeseed drying conditions affect the seed quality, total oil and germination capacity. hence in this research the effects of different tempera...
abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
the present study seeks to determine the effect of explicit instruction of metacognitive strategies on iranian high school students’ reading comprehension ability. it also attempts to investigate the relationship between the learners reading comprehension and metacognitive strategies. furthermore, the study investigates whether iranian efl female high school students are high, medium, or low me...
background and purpose: according to fao's report, lentil yield in iran is much lower than average yield in the world. this is due to low quality seedling production, low germination and emergence capacity, biotic and abiotic stresses and poor seedling establishment which was forced to looking for a way to enhance these components. seed priming is one of the strategy for increasing the rat...
Poor emergence resulting in inadequate stand establishment is a major problem associated with direct-seeded rice production, especially for semidwarf cultivars. In order to gain information on the problem, plant type related to gibberellic acid (GA3) and seeding depth was studied. A total of 21 cultivars including 9 semidwarfs and 12 talls had seed treated with GA3 at 25 parts per million (ppm)...
this study was carried out to evaluate the association between laboratory seed characteristics and seedling emergence of canola cultivars that it's were produced under different irrigation regime and planting date. the treatments were included two planting date and two levels of irrigation (main factors) and seeds of five canola cultivars (sub factor) which in first year (2006-2007) had be...
tuberose aesthetically and commercially is an important flower that its importance is due to its potential for trade of cut flower, long vase life and essential oil industry. it is cultivated commercially by bulbs is needed to their storing properly after the harvest and quiescence to increase yield and flowering quality so that can be regulated flowering time according to market. experiments w...
