Genetic Diversity Among Nile Delta Isolates Of Rhizoctonia Solani Kühn Based On Pathogenicity, Compatibility, Isozyme Analysis And Total Protein Pattern, Yehia A.G. Mahmoud, Reda M. Gaafar, H. M. Mubarak
Turkish Journal of Botany
The present study obtained 12 isolates from Rhizoctonia solani Kühn isolated from Cotton L., Trifolium L. and Vicia faba L. from different localities in the Nile Delta of Egypt. All strains were pathogenic and caused seed rot, wilt, stunting, and pre-emergence and post-emergence damping-off. The isolated strains produced different forms of infection cushions that ensure the pathogenicity of these strains. SDS-PAGE of the 12 R. solani isolates showed that although the R. solani isolates were isolated from very divergent host plants, the total soluble protein patterns among them were similar. Isozyme analysis revealed higher polymorphism among R. solani isolates using …

Germination And Seedling Behaviours Of Seeds Of Peltophorum Pterocarpum D.C.Baker Ex K.Heyne Growing Under Motor Vehicle Emission, Muhammad Shafiq, Muhammad Zafar Iqbal
Turkish Journal of Botany
Motor vehicle emission showed toxic effects on seed germination and seedling growth of Peltophorum pterocarpum D.C.Baker ex K.Heyne. Germination and growth of P. pterocarpum seeds were significantly (P < 0.05) affected in the seeds collected from the polluted areas as compared to the less polluted areas. A higher percentage of decrease in seed germination was found for the seeds collected from the extremely polluted area, followed by very much polluted, polluted, and a little polluted areas as compared to the unpolluted area (control). Seedling and root lengths were also highly decreased for the seeds of the same species collected from the extremely polluted area as compared to the control. A high percentage of seedling dry weight was found for the seeds of the same species collected from the extremely polluted area (62%), followed by very much polluted area (58%), polluted area (38%), and a little polluted area (28%) as compared to the control. According to the tolerance test, seedling growth of P. pterocarpum showed the lowest percentage of tolerance in the samples collected from the extremely polluted area (53%), followed by very much polluted area (71%), polluted area (89%), and a little polluted area (92%) as compared to the campus.

The Effect Of Seed Mass On Germination, Seedling Survival And Growth In Prunus Jenkinsii Hook.F. & Thoms., Krishna Upadhaya, Harendra Nath Pandey, Pynsakhiat Law
Turkish Journal of Botany
The effect of seed mass on germination, seedling survival and growth was investigated in Prunus jenkinsii Hook.f. & Thoms. (Rosaceae), an evergreen tree species. Seed mass varied from a minimum of 0.5 g to a maximum of 2.72 g. Seed mass had a significant effect on the percentage of seeds that germinated: 28%, 41% and 42%, respectively, of light- (1.5 g), intermediate- (> 1.5 to 2 g) and heavy-weight (> 2 g) seeds germinated. After 1 year of germination, the seedlings that arose from heavy-, intermediate- and light-weight seeds showed 80%, 63% and 42% survival, respectively. Seedling vigour, expressed in …

Temporal Changes In Environmental Characteristics And Diversity Of Net Phytoplankton In A Freshwater Lake, C. Chattopadhyay, T. C. Banerjee
Temporal Changes In Environmental Characteristics And Diversity Of Net Phytoplankton In A Freshwater Lake, C. Chattopadhyay, T. C. Banerjee
Turkish Journal of Botany
Temporal changes in the species composition, seasonal abundance, and diversity of net phytoplankton (NPP) were investigated in relation to some environmental characteristics of the water and sediment of Lake Krishnasayer, an ancient man-made shallow freshwater lake, located at Burdwan, India, between January and December 2003. In all, 43 species and 7 genera were identified from the weekly samples taken from a 1 x 1 x 1-m water column at sites I and II. The most abundant taxa were Cyanophyta (34.8%-37.8%) and Bacillariophyta (34.2%-34.3%), whilst Euglenophyta was the least abundant (4%-5.3%). The relationships (r) were significant (P < 0.05) and positive between water temperature and abundance of Euglenophyta, Secchi transparency, and Chlorophyta and Bacillariophyta, dissolved oxygen and Chlorophyta, dissolved chloride, and Cyanophyta and Euglenophyta, phosphate-phosphorus and Cyanophyta, and organic carbon and Bacillariophyta. In contrast, the relationships (r) were significant (P < 0.05), but inverse between water temperature and abundance of Bacillariophyta, Secchi transparency and Euglenophyta, dissolved chloride and Bacillariophyta, nitrate-nitrogen and Euglenophyta, and organic carbon and Euglenophyta. Furthermore, regression coefficients (b) indicated a significant (P < 0.05) positive relationship between Secchi transparency and overall NPP abundance, and a significant (P < 0.05) inverse relationship between silica and overall NPP abundance. The diversity indicated high values with peaks in species abundance in March, May, and September at site I, and in May, September, and November at site II. The seasonal abundance and frequency of occurrence for a few dominant species of Cyanophyta (e.g., Anabaena circinalis, Nostoc carneum, Oscillatoria formosa, Rivularia haematitis, and Spirula subsalsa), Chlorophyta (e.g., Spirogyra communis, Ulothrix tenerrima, and Zygnema pectinum), Euglenophyta (e.g., Euglena viridis), and Bacillariophyta (e.g., Cyclotella glomerata, Navicula capitata, Nitzschia acicularis, and Pinnularia major) in the surface water of this lake were 3.3%-5.5%, respectively.

Combining Ability Analysis Of Yield And Yield Components In Tomato (Lycopersicum Esculentum Mill.), Mohammad Mofidul Hannan, Manosh Kumar Biswas, Mohammad Bulbul Ahmed, Monzur Hossain, Rafiul Islam
Turkish Journal of Botany
The nature of the inheritance of plant height at 60 days, number of flowers per cluster, number of fruits per plant, fruit weight per plant, and number of seeds per fruit was studied from a 10-parent diallel cross of Lycopersicum esculentum Mill. Due to their high general combining ability effects, Pusharubi, Bari-4, and Dynasagor parents were suggested for future hybridisation programmes. For yield, the crosses Deshy x Ratan, Deshy x Epoch, Dynasagor x Ratan, Bari-4 x Pusharubi, and Dynamo x Namdhari had good specific combining ability effects and they were recommended because they produce stable performing rare transgressive segregants.

Effects Of Salinity: Calcium Interaction On Growth And Nucleic Acid Metabolism In Five Species Of Chenopodiaceae, Essam E. M. Abo-Kassem
Effects Of Salinity: Calcium Interaction On Growth And Nucleic Acid Metabolism In Five Species Of Chenopodiaceae, Essam E. M. Abo-Kassem
Turkish Journal of Botany
Seed germination, seedling growth, and some enzyme activity of nucleic acid metabolism were studied in 5 members of Chenopodiaceae [Beta vulgaris L., Chenopodium quinoa Willd., Spinacea oleracea L., Allenrolfia occidentalis (S.Watson) Kuntze, Atriplex hortensis L.] under NaCl salinity alone or combined with 0.5 mM CaSO_4. High salinity delayed radical emergence and decreased germination percentage in all plants. Combined CaSO_4 reduced inhibition of seed germination in B. vulgaris, S. oleracea, and A. hortensis, but increased it in C. quinoa and A. occidentalis. CaSO_4 reduced plant growth to a greater degree than high salinity did. High salinity decreased total nucleic acid content …
