dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...
For the purpose of graphical analysis and estimation of genetic parameters related to yield and its components, six tobacco genotypes was crossed in half -diallel mating design. In this study, the F2 progenies and their parents were evaluated in a randomized complete block design with three replications. The results of analysis of variance indicated a significant difference between genotypes fo...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
three separate experiments were conducted to investigate micropropagation of four pear cultivars. in the first trial, the effect of four cultural media (ms, ms/2, msn/2 and mql) were compared on such traits as shoot length, shoot number and color of leaf. from among the media, ms/2 and msn/2 resulted in the most shoot proliferation and the longest shoots respectively. ms medium produced green d...
abstract in order to investigate the effect of different ratios of cocopeat and vermicompost as a cultural media on seed emergence and some qualitative and quantitative characteristics of sweet pepper transplant (cv. colifornia wonder). the treatments include: vermicompost + cocopeat (3:1), vermicompost + cocopeat (1:3), vermicompost + cocopeat (1:1) (v/v) and normal soil of transplant. the tre...
Carrizo citrange (Citrus sinensisxPoncirus trifoliata) is a citrus hybrid widely used as a rootstock, whose genetic manipulation to improve different growth characteristics is of high agronomic interest. In this work, transgenic Carrizo citrange plants have been produced overexpressing sense and antisense CcGA20ox1 (a key enzyme of GA biosynthesis) under control of the 35S promoter to modify pl...

The invasive species Elodea nuttallii was recorded for the fi rst time in the Croatian fl ora in 2006, in the drainage channels of Kopački rit (Baranja). After its establishment, E. nuttallii begins to spread to the eastern and northern part of the drainage channel network from 2006–2009. High water levels are responsible for the linear spreading direction of E. nuttallii, E. nuttallii and E. c...
Juvenile growth and bud set phenology were analyzed to study the biological basis of heterosis (hybrid vigor) in interspecific hybrids of Populus tremuloides Michx. (T) and P. tremula L. (Ta). Growth, measured as seedling volume index, was significantly higher for each of the two reciprocal interspecific crosses, T x Ta and Ta x T, than for the T x T intraspecific cross. Broad-sense heritabilit...
