Salt effects on seed germination and seedling emergence of two Acacia species
Germination is the first stage in plant life cycle confronted with soil salinity and because of expanded saline areas around the world it is important to determine salt effects on this stage. In this study, we report an in vitro procedure for studying germination of Acacia spp. under salt stress with different NaCl and KCl concentrations. Seeds of Acacia tortilis (Forssk.) Hayne and Acacia oerf...
متن کاملeffects of concentrated acid and hot water scarification treatments on germination parameters of tamarindus indica and acacia arabica
tamarinda (tamarindus indica) and indian gum arabica (acacia arabica) are two ornamental trees of beautiful shape, extensive shading, and tolerant to high temperatures, making them suitable alternatives for landscape design in warm- arid regions. tamarinda and indian gum arabica are commonly propagated by seed. however, seed physical dormancy causes delay in seed germination. this study was car...
متن کاملComparative Salt Tolerance Study of Some Acacia Species at Seed Germination Stage
Objective: The purpose of this study was to assess and compare the seed germination response of six Acacia species under different NaCl concentrations in order to explore opportunities for selection and breeding salt tolerant genotypes. Methodology: Germination of seeds was evaluated under salt stresses using 5 treatment levels: 0, 100, 200, 300 and 400 mM of NaCl. Corrected germination rate (G...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولDormancy and Germination Pre-treatments in Willamette Valley Native Plants
Seeds from 30 species of grasses and forbs native to Pacific Northwest prairies were tested for physical and physiological dormancy. The physical dormancy was determined by mechanically and chemically scarifying seeds. Physiological dormancy was evaluated with cold stratification before germination. Experiments were analyzed individually with ANOVA analysis, and by seed lots through time using ...
