Turkish Journal of Botany
Allium dentiferum Webb & Berthel and Allium dodecanesii Karavokyrou & Tzanoudak were collected during a floristic study of South Anatolia. A. dodecanesii is reported as a new record for the flora of Turkey. Although collected earlier by Aznavour, Bothmer, and Brullo, specimens of A. dentiferum were misinterpreted and the species was thus not recorded for the flora of Turkey. We provide drawings and photographs of the species, and maps of their distribution in Turkey.

A Survey Of The Vascular Flora Of Beaufort County, South Carolina, Daniel Payne
All Theses
Beaufort County has historically been one of the most poorly botanized counties in the state. Geographically, it lies farther from the major research institutions than most other counties and has therefore received little attention from modern botanists. Major waterways, numerous private communities and an oppressive summer climate further complicate botanical research. Beaufort has one of the fastest growing human populations in the state. Natural areas are rapidly being converted into residential and commercial developments. An understanding of the county's flora is necessary to focus conservation efforts to preserve critical habitat and develop management plans for maintaining biodiversity. This project was …

Enhanced Adventitious Shoot Regeneration From Aerial Stem Explants Of Ginger Using Tdz And Its Histological Studies, Adinkudikuyyal Lincy, Bhaskaran Sasikumar
Turkish Journal of Botany
A protocol for direct plantlet regeneration from aerial stem explants of ginger (Zingiber officinale Rosc.) has been developed. Adventitious shoots and roots were regenerated from in planta aerial stem explants of 2 ginger varieties viz. var. 'Jamaica' and var. 'Varada'. Maximum shoot and root regeneration were observed in the cultures containing TDZ and IBA (1:1; 1:0.1 mg L-1) in both varieties. Cultures containing TDZ alone showed poor shoot and root formation. Histological studies revealed that the shoot initials originated from the primary thickening meristem and apical meristem, while the root primordial originated from the primary thickening meristem present in the …

Development Of A Highly Responsive Leaf-Based Regeneration System For Peperomia Species, Mohammad Ahmadabadi, Ralph Bock
Turkish Journal of Botany
Several species in the genus Peperomia Ruiz & Pav. have giant chloroplasts in the palisade parenchyma of their leaves. Because of this unique feature, Peperomia metallica L. Linden & Rodigas has become a valuable model plant for studying plastid biology. However, the use of Peperomia for molecular studies has been limited by the lack of efficient regeneration and transformation protocols. In this work, we aimed to develop a reliable regeneration system for Peperomia from leaf explants. Using MS medium complemented with different combinations of phytohormones, a highly efficient in vitro regeneration protocol was developed for P. metallica and P. peduncularis, …

Male Individuals In Cultivated Fritillaria Persica L. (Liliaceae): Real Androdioecy Or Gender Disphasy?, Elisa Mancuso, Lorenzo Peruzzi
Turkish Journal of Botany
In the last twenty years the growing number of studies about the reproductive biology in angiosperms has brought to light new cases of andromonoecy and androdioecy, the rarest sexual models among flowering plants. Female-sterile sexual systems, especially within order Liliales and family Liliaceae, often seem to occur in the particular form of size/age dependent sex allocation, known as "gender disphasy". The presence of male individuals of Fritillaria persica (Liliaceae) is here documented. Comparative morphological and functional sexual expression of this species, among males and hermaphrodites, was investigated by means of flowers counting, morphometric measurements of plants and pollen-grains, pollen viability …

Carbon Dynamics In A Phragmites Australis Invaded Riparian Wetland, Steven Walters
School of Natural Resources: Dissertations, Theses, and Student Research
Invasive plant species are widely recognized as a major threat to biodiversity and ecosystem stability. Wetland ecosystems tend to be much more susceptible to invasions because of their location on the landscape where water, nutrients, and the impacts of disturbances accumulate. Invasive plants have the ability to alter ecosystem processes and community/population dynamics. The ability of invasive plants to alter these processes can have profound economic consequences. In the United States, control of invasive wetland species alone costs approximately 155 million dollars annually. The state of Nebraska spends 2 million dollars annually controlling invasive plant species in the Platte River …
