effect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولImproving germination of Prunus avium L. seeds
To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...
متن کاملEffect of ventilation on growth of Prunus avium seedlings grown in treeshelters
Treeshelters are widely used to protect tree seedlings against animal browsing or rubbing. They reduce the tree transpiration as a result of the low ventilation rate of the shelter. Photosynthesis is impeded by low levels of available CO2 due to poor gas exchange with the outside. We assess the impact of ventilating a treeshelter on the microclimate, on the transpiration and on the photosynthes...
متن کاملEffect of temperature on pollen tube kinetics and dynamics in sweet cherry, Prunus avium (Rosaceae).
Prevailing ambient temperature during the reproductive phase is one of several important factors for seed and fruit set in different plant species, and its consequences on reproductive success may increase with global warming. The effect of temperature on pollen performance was evaluated in sweet cherry (Prunus avium L.), comparing as pollen donors two cultivars that differ in their adaptation ...
