An Examination Of Relationships Between Vegetation And Rainfall Using Maximum Value Composite Avhrr-Ndvi Data, Murat Karabulut
An Examination Of Relationships Between Vegetation And Rainfall Using Maximum Value Composite Avhrr-Ndvi Data, Murat Karabulut
Turkish Journal of Botany
Global vegetation monitoring with remotely sensed data has the potential of improving our knowledge about the characteristics and spatial distribution of the earth's land cover. The purpose of this study was to assess vegetation response to different rainfall regimes using bi-weekly MVC (Maximum Value Composite) AVHRR (Advanced Very High Resolution Radiometer) data. The results from this research showed that the NDVI (Normalised Difference Vegetation Index) has the potential for evaluating vegetation state, which is related to seasonal variations in climatic conditions. Extreme climatic events such as droughts and abundant moisture conditions can have a strong impact on vegetation development and …

On The Presence Of Heterocapsa Pygmaea A.R.Loebl. (Peridiniales, Dinophyceae) In The Northern Levantine Basin (Eastern Mediterranean), Zahi̇t Uysal, Mitsunori Iwataki, Tufan Koray
Turkish Journal of Botany
The presence of the dinoflagellate Heterocapsa pygmaea A.R.Loebl. in bloom quantity is reported for the first time from Mersin Bay (northern Levantine basin, eastern Mediterranean). Further, it is the only species of the family Heterocapsaceae reported from Turkish seas (southern Black Sea, the Sea of Marmara, Aegean Sea, and north-eastern Mediterranean). Our observations on the fine structure of the body scale of the specimen suggested that the scale morphology is identical to that of H. pygmaea.

Polyphenol Oxidase Activity During Rooting In Cuttings Of Grape (Vitis Vinifera L.) Varieties, Hayrullah Yilmaz, Tuncer Taşkin, Bi̇rol Otludi̇l
Turkish Journal of Botany
Polyphenol oxidase (PPO) activity was investigated during rooting in cuttings from three different grape cultivars (Vitis vinifera L. cvs. Muscat, Cardinal and Perlelte), and the enzyme activity and rooting ability were compared. Rooting was observed on the Muscat and Perlelte cuttings, but not on the Cardinal cuttings. PPO activity started to increase in the early stage of the experiment, and decreased after root emergence in the Muscat and Perlelte cuttings. However, enzyme activity started to increase in the early stages and continued throughout the experiment in the Cardinal cuttings. No apparent correlation was found between PPO activity and rooting ability …

Changes In Abscisic Acid And Indole-3-Acetic Acid Concentrations In Funalia Trogii (Berk.) Bondartsev & Singer And Phanerochaete Chrysosporium Burds. Me446 Subjected To Salt Stress, Serpi̇l Ünyayar
Turkish Journal of Botany
Variations in abscisic acid (ABA) and indole-3-acetic acid (IAA) concentrations were studied in Funalia trogii (Berk.) Bondartsev & Singer and Phanerochaete chrysosporium Burds. ME446 subjected to salt stress. The levels of ABA and IAA were determined by gas chromatography (GC) and UV-VIS spectrophotometry. The levels of hormones vary in the regulation of growth and in response to stress. It was found that ABA concentrations were higher in the salt stressed groups than in the control groups, whereas IAA concentrations were lower. These results show that, in fungi, ABA concentrations are positively and IAA concentrations negatively correlated with salt stress.

An Experimental Approach To Examining The Effect Of Water Depth And Lemna Minor L. On Algal Growth, Hani̇fe Özbay
Turkish Journal of Botany
In order to test how both water depth and Lemna minor L. affect the growth rate of algae, two different experiments were designed. In the first experiment, Scenedesmus quadricauda (Turp.) Breb. was cultured in sterilized Steinberg solution with reduced N and P levels in plastic containers at depths of 5, 10, 15 and 20cm. At the end of the experiment, differences in algal growth with depth were found to be significant between a) 5 cm with 10 cm, 15 cm and 20 cm, and b) 10 cm with 15 and 20 cm depth treatments (p

Effect Of Indole-3-Butyric Acid On In Vitro Root Development In Lentil (Lens Culinaris Medik.), Khalid Mahmood Khawar, Sebahatti̇n Özcan
Effect Of Indole-3-Butyric Acid On In Vitro Root Development In Lentil (Lens Culinaris Medik.), Khalid Mahmood Khawar, Sebahatti̇n Özcan
Turkish Journal of Botany
Lentil is an important crop of the family Leguminosae and is notoriously recalcitrant to rooting in vitro. Shoots of cultivar \"Ali Dayı\" of lentil obtained after culturing seeds for 10 days on MS medium were isolated and rooted on MS medium containing indole-3-butyric acid (IBA) at concentrations of 0.25, 0.5, 1.0 and 2.0 mg/l. The primary response was obtained after 4 weeks; 0.25 mg/l IBA gave the best results, with a rooting percentage of 25%, mean number of 7.87 roots along with mean root length of 7.13 cm. However, all other concentrations of IBA failed to induce roots.
