Airborne Pollen Concentration In Kütahya, Adem Biçakci, Osman Nuri̇ Benli̇oğlu, Di̇lek Erdoğan Jan 1999

Airborne Pollen Concentration In Kütahya, Adem Biçakci, Osman Nuri̇ Benli̇oğlu, Di̇lek Erdoğan

Turkish Journal of Botany

The airborne pollen cocentration in the atmosphere of Kütahya was determined by gravimetry with a Durham sampler in 1996. During this study, 23 taxa of arboreal and 14 taxa of herbaceous pollen grains were collected and identified. Pollen from the following taxa were also found to be prevalent in the atmosphere of Kütahya: Pinus L., Cupressaceae, Platanus orientalis L., Quercus L., Oleaceae, Gramineae, Urticaceae, Chenopodiaceae/ Amaranthaceae, Compositae and Plantago L. The effects of meteorological factors (temperature, humidity, wind speed, rainfall) on pollen production, dispersal and concentration in the atmosphere of Kütahya were observed.


In Vitro Micropropagation Of Sainfoin ( Onobrychis Viciifolia Scop.), Cengi̇z Sancak Jan 1999

In Vitro Micropropagation Of Sainfoin ( Onobrychis Viciifolia Scop.), Cengi̇z Sancak

Turkish Journal of Botany

A method for in vitro micropropagation of sainfoin was developed. Following optimization of the growth regulator combinations in the media, large numbers of shoots were propagated from a single embryonic axis within 8 weeks on Murashige and Skoog (MS) media supplemented with combination of different 6-benzylaminopurine (BAP), indole-butyric acid (IBA) and ?-naphthaleneacetic acid (NAA) concentrations. The highest number of shoot multiplication was obtained on the media containing 2 mg/l BAP and either 0.05 or 0.1 mg/l IBA, and on the media supplemented with 2 mg/l BAP and either 0.05, 0.1 or 0.5 mg/l NAA, or 8 mg/l BAP and 0.05 …


The Moss Flora Of The Uludağ National Park (Bursa/Turkey), Barbaros Çeti̇n Jan 1999

The Moss Flora Of The Uludağ National Park (Bursa/Turkey), Barbaros Çeti̇n

Turkish Journal of Botany

Field studies were conducted to determine the flora of Uludağ (Bursa) National Park during 1988, 1989 and 1996. Almost 180 plant specimens were collected in these studies. After the identification of these specimens, 85 taxa at specific and sub-specific ranks were determined. Of these, 28 taxa are new to the Al grid-square. In addition, Polytrichum commune var. perigoniale (Michx.) Hampe is a new record for the moss flora of Turkey.


The Effect Of Uracil On The Germination And Growthof Some Leguminous Plants, Yusuf Turan, Muhsi̇n Konuk Jan 1999

The Effect Of Uracil On The Germination And Growthof Some Leguminous Plants, Yusuf Turan, Muhsi̇n Konuk

Turkish Journal of Botany

All known pyrimidine and pyrimidine-derived secondary producs originate from uracil or its precursor, uracil-6-carboxylic acid. The biosynthesis of these products has been suggested to be uracil detoxication mechanisms. The possible toxic effects of uracil on the germination and growh of Pisum sativum L. cultivar Meteor, Lathyrus tingitanus L. in which pyrimidine-derived secondary products occur naturally, and of Phaseolus aureus Roxb. and Glycine max (L.) Merr., in which these compouns do not occur, were examined. The results show that the germination and growth of the P. aureus and G. max seeds under investigation were considerably inhibited by exogenous uracil. The effect …

The Liverworts ( Hepaticae) Of Uludağ National Park (Bursa), Barbaros Çeti̇n

Turkish Journal of Botany

During the vegetation period, a total of 52 plant specimens were collected from Uludağ National Park (Bursa) between 1988 and 1989. At the end of this investigation, 23 liverwort species were identified, belonging to 15 families and 17 genera. Of these, 4 taxa are new for the Al grid-square. Jungermannia hyalina Lyell, Marsupella funckii (Web. & Mohr) Dum and Calypogeia azureaStotler & Crotz, are reported for the second time from Turkey.

The Woody Vegetation Of The Kelkit Valley, Fergan Karaer, Mahmut Kilinç, H. Güray Kutbay Jan 1999

The Woody Vegetation Of The Kelkit Valley, Fergan Karaer, Mahmut Kilinç, H. Güray Kutbay

Turkish Journal of Botany

In this work, the forest, macchie and hygrophilous vegetation of Kelkit Valley was studied. Interesingly the study area is a transitional zone along the boundries of Central Anatolia and the Central and East Black Sea regions. From the phytogeographical point of view this area is situated between the Euro-Siberian and Irano-Turanian floristic regions. This study was carried out according to the Braun-Blanquet method. Twelve plant associations and 2 subassociations were identified belonging to four different vegetation types. Ten of the associations and two subasociations here are determined as new associations. Vegetation tables are given.


An Investigation On Rooting Of Juglans Regia L. Hardwood Cuttings, Tohi̇t Güneş Jan 1999

An Investigation On Rooting Of Juglans Regia L. Hardwood Cuttings, Tohi̇t Güneş

Turkish Journal of Botany

The rootinf of Juglans regia L. ( Juglandeceae) hardwood cuttings was investigated. The cuttings were treated with a solution of 100 and 1000 ppm IBA concentrations. One and two year old shoot cuttings were used and carbohydrate changes were recorded during rooting. No rooting was observed in any cutting, 32% callus formation was observed on the basal parts of the cuttings. The flower buds burst earlier than the vegetative buds and developed male or female flowers. Callus formation rate or bud burst was not significantly affected by the treatment of IBA. Carbohydrate changes occurred during the culture, but there was …

Genetic Variation In Chrysopsis Floridana Small, The Endangered Florida Golden Aster, As Revealed By Random Amplification For Polymorphism Detection (Rapd), Laurie Lysle Walker Markham Nov 1998

Genetic Variation In Chrysopsis Floridana Small, The Endangered Florida Golden Aster, As Revealed By Random Amplification For Polymorphism Detection (Rapd), Laurie Lysle Walker Markham

USF Tampa Graduate Theses and Dissertations

Chrysopsis fioridana Small (Asteraceae) is a federally endangered plant endemic to the Tampa Bay area of west central Florida. It is confined to the sand pine scrub community, growing in open, sunny, and sandy areas or in disturbed areas at the edges of scrub. As a means ofassessing the genetic variability ofthis species, eight populations in Hillsborough County were compared with a seed stock collection housed at Bok Tower Gardens in Lake Wales using random amplification for polymorphism detection (RAPD). The objectives of this study were to (I) describe the overall genetic variation among and within populations and subpopulations of …

Bird Use Of Riparian Vegetation Along The Truckee River, Califonia And Nevada, Suellen Lynn, Michael L. Morrison, Amy J. Kuenzi, Jennifer C. C. Neale, Benjamin N. Sacks, Robin Hamlin, Linnea S. Hall Oct 1998

Bird Use Of Riparian Vegetation Along The Truckee River, Califonia And Nevada, Suellen Lynn, Michael L. Morrison, Amy J. Kuenzi, Jennifer C. C. Neale, Benjamin N. Sacks, Robin Hamlin, Linnea S. Hall

Great Basin Naturalist

The Truckee River in California and Nevada is subject to diverse water regimes and a corresponding variety of flow rates. Original riparian vegetation has been altered by these variable flow rates and by a variety of human uses resulting in loss of native riparian vegetation from its historic extent. We conducted bird surveys along the Truckee River during spring 1993 to (1) determine relationships between birds and the present vegetation; (2) determine the importance of different vegetation types to sensitive bird species that have declined recently in the western United States due to competition from exotic plant species, cowbird ( …

Ecological Evaluation For The West Ash Creek Potential Research Natural Area, Pine Ridge Ranger Unit, Nebraska National Forest, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The West Ash Creek Potential Research Natural Area is located within pastures 6, 7, and 11 of the Pine Ridge Unit of the Nebraska National Forest ca 18 mi. (30 km) southwest of Chadron, Nebraska. The area consists of ca 1020 acres of mostly successional pine forest burned in a 1985 wildfire, with unburned forest, some grassland, and riparian canyon bottoms. The area is within the Pine Ridge ecosystem of the White River watershed in northwestern Nebraska. The area has remained ungrazed nearly continuously since 1986.

This document was prepared to provide the Forest Service with information to determine the …
