The Effect Of Glycinebetaine On The Heat Stability Of Photosynthetic Reactions In Thylakoid Membranes, Yagut M. Allakhverdieva, Mahir D. Mamedov, Ralphreed A. Gasanov Jan 2001

The Effect Of Glycinebetaine On The Heat Stability Of Photosynthetic Reactions In Thylakoid Membranes, Yagut M. Allakhverdieva, Mahir D. Mamedov, Ralphreed A. Gasanov

Turkish Journal of Botany

Heat inactivation of various photosynthetic electron transport reactions were investigated in the presence/absence of glycinebetaine (betaine) in unstacked thylakoid membranes from spinach. The activity of Photosystem II (PS II) is more sensitive to heat than that of Cytochrome bf (cyt.bf) and Photosytem I (PS I) complexes. The data obtained clearly demonstrated the protection of PS II and PS I electron transfer by betaine under high temperatures. The phenomena observed are probably related to the stabilization of the higher-order structures of PS II and PS I by betaine.

Using The Green Flagellate Euglena Gracilis Klebs As Physiological Dosimeter: Is A Long-Term Bioassay More Significant Than A Short-Term One?, Roman A. Danilov, Nils C. A. Ekelund

Turkish Journal of Botany

The use of short-term tests with E. gracilis Klebs in order to assess toxicity cannot be viewed as absolutely preferable. At least in the case with wastewater from the pulp and paper industry, 7 day-tests could lead to more explanatory and significant results.


The Effects Of Different Mineral Nutrients On The Levels Of Cytokinins In Maize (Zea Mays L.), Peyami̇ Battal, Beki̇r Ti̇lekli̇oğlu Jan 2001

The Effects Of Different Mineral Nutrients On The Levels Of Cytokinins In Maize (Zea Mays L.), Peyami̇ Battal, Beki̇r Ti̇lekli̇oğlu

Turkish Journal of Botany

In this study, Z (trans-Zeatin) and ZR (trans-Zeatin Riboside) levels in the roots, stems, leaves, flowers and fruits of maize plants (Zea mays L.) were determined using high performance liquid chromatography (HPLC). Plants were grown in media containing macro elements (nitrogen, phosphorus, potassium, calcium, magnesium, sulphur and iron) in optimum, deficient and excess concentrations. According to the average Z values for all periods, the highest Z levels were determined in the roots of plants treated with excessive P (-P); in stems, female flowers treated with excessive K (-K) and in leaves and kernels treated with excessive Ca (-Ca).

Pollen Flora Of Pakistan-Xxxi Capparidaceae, Anjum Perveen, Mohammad Qaiser Jan 2001

Pollen Flora Of Pakistan-Xxxi Capparidaceae, Anjum Perveen, Mohammad Qaiser

Turkish Journal of Botany

The pollen morphology of 14 species belonging to seven genera viz., Cadaba Forssk., Capparis L., Cleome L., Dipterygium Decaisne, Gynandropsis DC., Maerua Forssk., of the family Capparidaceae, was investigated using a light microscope and scanning microscope.

Pollen grains usually radially symmetrical, isopolar, sub-prolate to prolate, generally tricolporate, often tetra-colporate. Tectum generally spinulose, or striate-rugulate, or rugulate-reticulate often sub-psilate.

The Origin Of The 'Wild Orchards' Of Central Anatolia, Henk Woldring, Rene Cappers Jan 2001

The Origin Of The 'Wild Orchards' Of Central Anatolia, Henk Woldring, Rene Cappers

Turkish Journal of Botany

Palynological investigations have revealed that the deforestation of Central Anatolia started c. 4000 BP. At present, most of the land is cultivated and only small patches of woodland occur in remote mountain areas. These woodlands are dominated by deciduous oaks ( Quercus L. spp.) or locally by junipers ( Juniperus L. spp.). A pattern of scattered fruit trees, the so-called wild orchards, characterizes the cultivated fields. Another type of arboreal vegetation is found on isolated rock outcrops in the fields. Surveys of the vegetation types show that oaks are uncommon among the fields and on the rock outcrops. By contrast, …

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 …

Turkish Journal of Botany

The pollen morphology of 8 species belonging to a single genus, i.e., Impatiens L., of the family Balsaminaceae, was studied by light microscope and scanning microscope. It is stenopalynous in nature. Pollen grains oblate to sub-oblate, rectangular, tetra-colpate, colpi very short (brevicolpate). Tectum reticulate. Palynology of the family confirms its monotypic status.


Pollen Flora Of Pakistan - Xxviii: Resedaceae, Anjum Perveen, Mohammad Qaiser Jan 2001

Pollen Flora Of Pakistan - Xxviii: Resedaceae, Anjum Perveen, Mohammad Qaiser

Turkish Journal of Botany

The pollen morphology of 4 species belonging to the 3 genera of the family Resedaceae was investigated using a light microscope and scanning microscope. Pollen grains usually radially symmetrical, isopolar, sub-prolate, rarely prolates pheroidal, tricolpate or tricolporate. Tectum reticulate. However, apertural type and pollen shape are the most significant pollen characters for delimiting the genera. On the basis of apertural types 2 distinct pollen types are recognized, namely, I: Tricolpate-type and II: Tricolporate-type.

Different distribution patterns discriminated in the study area were used to evaluate air quality. A predominant part of the city area is heavily polluted; this pollution decreases in green spaces and in the outer zone of the study area. The best air quality values were determined in the southern and western parts of the city zone. A value of 7.3 for the width of the air quality classes shows …


The Clypeate Pollen Grains Of Turkish Iris L. (Iridaceae): Subgenus Scorpiris Sach, Emel Oybak Dönmez, Münevver Pinar Jan 2001

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 …

The Low Above-Zero Temperature Effect In The Zone Of Roots On Nitrate Reductase Activity In Pea Organs In The Process Of Vegetating, G. G. Vasilieva, N. V. Mironova, A. K. Glyanko Jan 2001

The Low Above-Zero Temperature Effect In The Zone Of Roots On Nitrate Reductase Activity In Pea Organs In The Process Of Vegetating, G. G. Vasilieva, N. V. Mironova, A. K. Glyanko

Turkish Journal of Botany

Experiments with pea (Pisum sativum L.) cv. Marat) in a phytotron chamber showed that the process of nitrate assimilation in pea organs depends on temperature in the zone of the roots and on the phase of development of the plants. The potential of tissues of different organs for nitrate reduction was compared to the amount of nitrates which they accumalated. A decrease in nitrate reductase activity during certain phases of development is assumed to be related to the process of formation and functioning of nodules.
