the effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...

Because the endosperm half of a barley seed produces several hydrolytic enzymes in response to added gibberellins (1, 4, 5, 8), it is an attractive experimental system for a study of the mechanism of action of gibberellic acid. The only living cells in the half seed are those of the aleurone layers. These are an apparently homogeneous collection of respiring, nondividing cells which have the hi...
متن کاملGibberellic Acid lnduces Vacuolar Acidification in Barley Aleurone
The roles of gibberellic acid (GA3) and abscisic acid (ABA) in the regulation of vacuolar pH (pH,) in aleurone cells of barley were investigated using the pH-sensitive fluorescent dye 2',7'-bis(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF). BCECF accumulated in vacuoles of aleurone cells, but sequestration of the dye did not affect its sensitivity to pH. BCECFloaded aleurone cells retained th...
متن کاملPhysiological Effects of Gibberellic Acid. X. Gibberellin-Like Substances by Germinating The Release of Barley Embryos
Sum,itmary. Barley embryos, completely free from endospernm, wvere excised from germinating grain at various times and al'lowed to diffuse into an aqueous medium for varying lengths of time. At the end of this time, the embrvos and ambient solutioins were separately extracted. Gibberellin-like activity in the extracts was determined with the barley endosperm bioassay using seed from the same va...
