Sources of Variation in Olive Flower and Fruit Populations

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...

Flower size variation in Rosmarinus officinalis: individuals, populations and habitats.

BACKGROUND AND AIMS Flowers are relatively invariant organs within species, but quantitative variation often exists among conspecifics. These variations represent the raw material that natural selection can magnify, eventually resulting in morphological divergence and diversification. This paper investigates floral variability in Rosmarinus officinalis, a Mediterranean shrub. METHODS Nine pop...

From the Olive Flower to the Drupe: Flower Types, Pollination, Self and Inter-Compatibility and Fruit Set

The Role of Olive Trees Distribution and Fruit Bearing in Olive Fruit Fly Infestation

The role of fruit bearing percentage in olive fruit fly infestation is investigated through a simulation model where the spatial law of dispersion distances were modeled via an appropriate exponential law. The dispersal of olive fruit flies was simulated for two distinct cases, an olive grove with no olive fruits and an olive grove with 100% olive fruit bearing. Results showed that when no oliv...

Chromosome Number Variation in Iranian Populations of Acorus calamus

Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
