Title : A Comparative Investigation On Two Different Populations of Papaver pilosum subsp. spicatum (Papaveraceae) endemic to Turkey
Abstract:
- How much do the populations differ from each other morphologically?
The two populations in the present study correspond to P. spicatum Boiss. & Balansa var. spicatum and var. luschanii Fedde, respectively, described by Cullen (1965) in the first volume of the Flora of Turkey. P. spicatum Boiss. & Bal. has been regarded as synonym of P. pilosum subsp. spicatum by Kadereit (1996) in the last volume of the Flora of Turkey (Özhatay 2000). According to the recent treatment of the genus Papaver sect. Pilosa (Kadereit 1996), the two varieties have been combined in a new status, P. pilosum subsp. spicatum.
In this section, we will present detailed morphological descriptions by photographs, illustrations and measurements on the two populations. In order to understand how much they differ from each other morphologically, we will make a morphological comparison between the two populations under the treatments of Cullen (1965) and Kadereit (1996). The number of flower in spike-like raceme, the peduncles of flowers, the posture of peduncles, the indumentum and shape of capsules are significantly different. We think that the two populations appear different enough morphologically from each other to be evaluated in different taxonomic categories.
- How much do the populations differ from each other anatomically?
We will present detailed anatomical descriptions of the investigated populations of P. pilosum subsp. spicatum by photographs and measurements in tables. The two populations had laticifers reflecting general characteristics of Papaveraceae family and the genus Papaver described by Metcalfe & Chalk (1950). However, certain anatomical differences were detected between the two populations, such as distribution of the xylem vessels in central cylinder of the roots, arrangement of vascular bundles in both the stems and the peduncles and density of trcihomes. Anatomical differences between the two populations support the morphological differences.
- How much do the populations differ anatomically from the other investigated Papaver taxa and some other members of the family Papaveraceae?
In this section, we will compare the populations with the other investigated Papaver taxa, anatomically. There are very few anatomical studies on the genus Papaver in the literature. Our anatomical results are to some extent comparable with those of P. somniferum L., P. rhoeas L., P. orientale L., P. dubium L. and some other members of the family Papaveraceae.
