QUESTION: Does water loss during drought stress represent an important physiological constraint on the evolution of flower size? ORGANISM: A genetically diverse population of Mimulus guttatus (yellow monkeyflower) originally sampled from an alpine meadow in Oregon, USA. METHODS: We grew plants of three different genotypic classes (small, medium, and large flowered) under both well-watered and d...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
Air-dried flower heads of 20 Finnish tansy genotypes were extracted with petroleum ether and analyzed using GC-MS. A total of 55 volatile compounds were detected, and 53 were identified. Of the tansy genotypes studied, 15 were well defined and five were mixed chemotypes. Complete linkage analysis differentiated the populations into six clusters. The most frequently found monoterpene was camphor...
1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...
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...
Preliminary study on Ipomoea phylogeny shows that species selection may influence flower-color evolution in this genus. Evolutionary transitions between pigmented flower and white flower appear to be highly asymmetrical. White-flowered lineages are less speciose than their pigmented sister clade and evolutionary transitions to white flowers occurred almost exclusively at the tip of phylogeny. A...
Pea cultivation in autumn has a higher yield compared to its spring cultivation. In order to investigate the possibility of changing the planting date of chickpea from spring to autumn in (Kerman province, Iran) and obtaining cultivars that could withstand cold winter and produce more yield, 63 chickpea genotypes were planted in pots at Dec/2016 and evaluated in field .The agronomic traits inc...
BACKGROUND AND AIMS Ultraviolet-B (UV-B) radiation effect on reproductive parts of the plants has received little attention. We studied the influence of UV-B radiation on flower and pollen morphology, pollen production and in vitro pollen germination and tube growth of six genotypes of soybean (Glycine max). METHODS Soybean genotypes were investigated by growing them under four levels of biol...
