In an effort to improve and promote the propagation of Terminalia sericea, the effects of temperature, photoperiod and growth regulators on seed germination were investigated. Seeds were tested with different temperature regime (10, 15, 20, 25, 30, 35 and 40C) and in photoperiod (4/20, 8/16, 12/12, 16/8 light/dark hrs and 24 hours continuous dark). Pre-treatments with growth regulators were don...
The effect of cadmium chloride concentrations (25.50, 75, and 100 mg/kg soil), seeds pre-irradiated by low doses of gamma rays (15, 30, 45, and 60 Gy), potassium chloride (60 mg/kg soil) and the combination of cadmium + gamma and cadmium + potassium on Brassica rapa germination, oxidative stress and antioxidant system were investigated under laboratory and greenhouse conditions. Germination per...
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
background: this work investigated the dosimetry limitations of the random and systematic uncertainties of sliding window (sw) intensity modulated radiation therapy (imrt). materials and methods: a varian 21ex linear accelerator, pinnacle3 treatment planning system and radiographic film dosimetry was used. the limitations of the sw were studied using beam modulation ranging from 2 to 100 mu/bea...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...
Ferula ovina Boiss. is one of grazing species whose seed germination faces certain problems. The dormancy characteristics of and optimum conditions for seed germination of this species have not been investigated so far. The present research was designed to investigate the effect of GA3 and moist chilling on seed germination of this plant. At first, a factorial the experiment in a completely ran...
