This research was conducted to determine the effects of different seaweed doses on yield and nutritional values of hydroponic wheatgrass (Triticum aestivum L.) juice in the climatization chamber of Karabuk University, Eskipazar Vocational School, Department of Crop and Animal Production between the dates of 15.01.2015 and 15.06.2015. In the research, four different seaweed doses (Control; 0, D1; 150, D2; 300, D3; 450 and D4; 600 ppm) and control were applied to irrigation water and their effects on the content of biomass rate, biomass and grass yield, grass juice yield and pH, plant height and root length, biomass and grass dry matter rate, grass juice energy and macronutrient values (protein, carbohydrate, fat, dietary fiber and ash) were analysed. According to the results, while the highest biomass and grass yield, plant height values were obtained from D1, D2, D3 and D4 treatments, the highest grass juice yield and root length were obtained from D3 treatment. The highest pH, grass dry matter content was obtained from control treatment. Seaweed dose treatments were not had influence on grass juice energy values. However, the rise in the grass juice yield was caused a rise in the total energy values in the unit area. D3 treatments can be recommendable to achieve the highest grass juice yield.

118 accessions of the genus Lycopersicon were characterized and evaluated to determinate the genetic potential, using the IBPGR descriptors. The experiment was conducted, using a complete random design and two repetitions. Characteristics concerned to the plant, fruit, yield components and resistence to insects and disease was studied. Important fenotipic differences were founded. The varieties of the cultivated specie L. esculentum, showed heigh productions per plant and heigh average fruit weight. The wild accessions showed heigh resistence to the insects and pathogens. ADBI8, ADB 400, 1600, 1601 and Rio Fuego accessions of the L. esculentum showd heigh productions per plant and heigh resistence to the insects and pathogens. | Mediante los descriptores de IBPGR se caracterizaron y evaluaron 118 introducciones del género Lycopersicon, en el Centro Experimental de la Universidad Nacional Sede Palmira. Se utilizó el diseño experimental de Bloques al azar con dos repeticiones; la parcela experimental estuvo constituida por seis plantas. Se estudiaron nueve caracteres relacionados con la planta, diez caracteres relacionados con el fruto, componentes del rendimiento y presencia o ausencia de plagas y enfermedades. Se encontró gran variabilidad para la mayoría de los caracteres. Las variedades de la especie cultivada, L. esculentum, presentaron las mayores producciones por planta y el mayor tamaño de fruto. Las especies silvestres; presentaron mayor resistencia a plagas y enfermedades. Se destacaron los siguientes variedades de L. esculentum por presentar altas producciones y tolerancia a plagas y enfermedades: ADB 18, ADB 400, 1600, 1601 Y Rio Fuego.

Collected blue-green algae (cyanobacteria) from freshwater sites throughout Tokat province and its outlying areas were isolated in laboratory environment and their morphological systematics were determined and also their species identifications were studied by molecular methods. Seven different species of blue-green algae collected from seven different sites were isolated by purifying in cultures in laboratory environment. DNA extractions were made from isolated cells and extracted DNAs were amplified by using PCR. Cyanobacteria specific primers were used to amplify 16S rRNA and phycocyanine gene regions using PCR. Phylogenetic identification of species were conducted by evaluation of obtained sequence analysis data by using computer software. According to species identification by sequence analysis, it was seen that molecular data supports morphological systematics.

En casa de malla de la Universidad Nacional de Colombia sede Palmira (3° 30' 45.6" N y 76° 18' 29.911" O, 1050 m.s.n.m., 23.5 °C y 77% de HR) se midieron los requerimientos hídricos del cilantro (Coriandrum sativum L.) variedad Unapal Precoso y se relacionaron con el rendimiento de follaje fresco y materia seca. Las plantas fueron sembradas en macetas con 6 kg de suelo y por ciclo de cultivo se aplicaron láminas de agua de 140, 160, 200 (testigo propuesta por Vallejo y Estrada, 2004), 240 y 280 mm. Se utilizó un diseño completamente al azar con cinco tratamientos, cuatro repeticiones y 36 plantas por unidad experimental. Cada día, durante la fase experimental, se realizaron mediciones de evapotranspiración y cada 35 días después de la siembra se midieron las producciones de follaje y biomasa. La mayor producción de follaje se obtuvo con 200 mm de agua, valor asociado con la mayor eficiencia en el uso de ésta, medida como producción de MS, (0.64 g/lt de agua aplicado). En la etapa de germinación el coeficiente Kc del cultivo (relación evaporación real/evaporación de referencia) fue de 0.83, 1.12 en la etapa de crecimiento lineal y 1.40 en la etapa de formación de tallo floral y cosecha. | An experiment was conducted to determine water requirements of coriander Unapal Precoso related to fresh foliage yield and dry matter. Plants were sown in pots with 6 kg of soil and water depths of 140, 160, 200 (witness proposed by Vallejo y Estrada, 2004), 240 and 280 mm were applied. A random complete block design was used with 5 treatments and 4 replications, with 36 plants per experimental unit. Daily evapotranspiration measurements were made. Production of foliage and biomass was evaluated 35 days after sowing. Increased production of foliage was obtained with 200 mm of water depth, value associated with greater efficiency in water use (0.64 grams of dry matter per liter of water applied). The crop Kc was determined: 0.83 at the stage of germination, 1.12 in linear growth stage and 1.40 on the stage of forming flower stems and harvesting.
