Testig Growth Of Elodea Nuttallii (Palnch.) H. St. John With Different Culture Media, Hani̇fe Özbay
Turkish Journal of Botany
The Growth rate of Elodea nuttallii (Planch.) H.St.John was tested in different culture media. Effects of snail was also determined on the growth rate of the plant.

Callus Development And Indirect Shoot Regeneration From Seedling Explants Of Sugar Beet ( Beta Vulgarisl.) Cultured In Vitro, Songül Gürel, Ekrem Gürel, Zeki̇ Kaya
Turkish Journal of Botany
For callus production, hypocotyl, cotyledon, petiole and leaf explants from seedlings of different sugar beet ( Beta vulgaris L.) breeding lines were cultured on MS medium containing BAP or KIN in combination with NAA or 2,4-D at 0.0, 0.5 or 1.0 mg/l. The use of both auxins in combination with 0.5 mg/l BAP or 0.5 mg/l KIN resulted in greater amounts of callus from all types of explants. However, hypocotyl and cotyledon explants produced significantly more callus than petiole and leaf explants when the means of all lines were taken into account. Two types of callus were usually obtained, white …

The Clypeate Pollen Grains Of Turkish Iris L. (Iridaceae): Subgenus Scorpiris Sach, Emel Oybak Dönmez, Münevver Pinar
Turkish Journal of Botany
The clypeate pollen grains of some species of Turkish Iris L. (Iridaceae) taxa belonging to the subgenus Scorpiris Spach have been investigated. Attention is given to characteristics of exine sculpturing and the exine shields using light microscopy and scanning electron microscopy. The pollen grains of the Scorpiris are shown to be uniform, especially with regard to pollen shape and exine sculpturing. However, a trend towards greater pollen size accompanied by higher exine shield number is noted from the less specialised taxa to the more specialised taxa. It is also considered that the clypeate pollen type is unique to subgenus Scorpiris …

Growth And Proline Content Of Germinating Wheat Genotypes Under Ultraviolet Light, Yavuz Demi̇r
Growth And Proline Content Of Germinating Wheat Genotypes Under Ultraviolet Light, Yavuz Demi̇r
Turkish Journal of Botany
The effect of ultraviolet light on the growth and proline contents of four wheat cultivars ( Triticum aestivum L., cvs. Bezostoja-1, Dogu-88, Turkey-13, Yayla-305) was investigated. Ultraviolet light inhibited the growth of all of the four wheat cultivars and increased the daily proline contents of both the radicle and coleoptile. Ultraviolet light is a stress factor in the growth of plants but the wheat cultivars tested produced proline against this stress. From the results obtained, it is suggested that proline can protect cells against damage induced by ultraviolet radiation.
