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.


Agrobacterium Tumefaciens-Mediated Transformation Of Sesame (Sesamum Indicuml.), Kemal Meli̇h Taşkin, A. Gülhan Ercan, Kenan Turgut Jan 1999

Agrobacterium Tumefaciens-Mediated Transformation Of Sesame (Sesamum Indicuml.), Kemal Meli̇h Taşkin, A. Gülhan Ercan, Kenan Turgut

Turkish Journal of Botany

Sesamum indicum L. cv. Özberk was infected with various Agrobacterium tumefaciens strains to screen susceptibility to infection by Agrobacteria. Following infection, tumorigenesis was efficient with wild type A. tumefaciens strains, A281 and A136 NC, and transgenic cells were obtained with disarmed A. tumefaciens strain LBA4404/pBI121, harbouring a reporter gene. At the wound sites, tumorigenesis induced by the succinamopine strain A281 was more extensive than by the octopine strain A136 NC.


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 …

Kansas Agricultural Experiment Station Research Reports

It might be a simple question, such as "Which tall fescue cultivars are best suited for use on lawns?" or possibly a more complicated one, such as "What causes the quality of my bentgrass greens to decline in July?" Answers to these questions and many others are contained in this 1999 edition of Turfgrass Research.


Transgenic Cotton Research Paves The Way For A New Industry In The Kimberley, Geoff Strickland, Amanda Annells Jan 1999

Transgenic Cotton Research Paves The Way For A New Industry In The Kimberley, Geoff Strickland, Amanda Annells

Journal of the Department of Agriculture, Western Australia, Series 4

The use of transgenic cotton varieties (INGARD®) in conjunction with t_x integrated pest management (IPM) systems in the Kimberley region is producing excellent yield and quality prospects for an emerging cotton industry in Western Australia. Geoff Strickland and Amanda Annells report on the value of transgenic cotton and the additional benefits being gained from the use of multi-faceted IPM systems.

Journal of the Department of Agriculture, Western Australia, Series 4

Cavity spot is the most serious disease affecting carrot production in Ly Western Australia. With carrots now being the State's most important horticultural export, Agriculture Western Australia has undertaken extensive research to ensure the export market continues to grow.


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.


Elaeagnus Angustifolial. As A Biomonitor Of Heavy Metal Pollution, Ahmet Aksoy, Uğur Şahi̇n Jan 1999

Elaeagnus Angustifolial. As A Biomonitor Of Heavy Metal Pollution, Ahmet Aksoy, Uğur Şahi̇n

Turkish Journal of Botany

The leaves of Elaeagnus angustifolia L. (Elaeagnaceae) were tested as a possible biomonitor of heavy metal pollution in Kayseri. Concentration of Pb, Cd and Zn were determined in unwashed and washed leaves and soils. Differences between the unwashed and washed samples varied according to the metal pollutant levels. Significant correlations were obtained between the heavy metal concentrations in surface soil and washed leaf samples. E. angustifoliawas found to be a useful biomonitor of the heavy metals investigated.

Soluble Sugar Composition Of Elaeagnus Angustifolial.Var. Orientalis (L.) Kuntze (Russian Olive) Fruits, F. Ahmet Ayaz, Asim Kadioğlu, Ali̇ True

Turkish Journal of Botany

Soluble sugar composition from ethanolic extract of Elaeagnus angustifoliaL. (Russian olive) ( Elaeagnaceae) collected from six different populations in the Gümüshane-Bayburt Valley was determined by gas chromatography. In the fruits, fructose and glu-cose were determined to be the major sugars. The analysis showed the occurrence of fructose and glucose in concentrations (w/w) of 32.62-34.60% and 23.37-24.10% (minimum-maximum), respectively. Sucrose was not detected in mature fruits while fruc-tose and glucose were identified as the major sugars among these populations.

Accelerating Variety Release With Double Haploids, Sue Broughton

Journal of the Department of Agriculture, Western Australia, Series 4

The use of plant tissue culture to produce special lines called doubled haploids is reducing the time taken to breed new varieties of cereal crops by up to three years. Sue Broughton outlines what doubled haploids are, how they are produced, and why they have been able to short circuit the usual lengthy breeding process.
