Some Characteristics Of The Stagnation Stage In The Development Of Silver Fir (Abies Alba Mill.) Trees In Selection Forests In Serbia, Damjan Pantic, Stanisa Bankovic, Milan Medarevic, Snezana Obradovic
Turkish Journal of Agriculture and Forestry
A period of stagnation in silver fir development has been recorded in all felled trees in selection forests of Serbia (233 trees on Mt. Goc and 451 trees on Mt. Tara). In the selection forests on Mt. Goc, the stagnation stage ranges between 40 and 330 years, but on Mt. Tara, it ranges from 15 to 185 years. It was concluded that the duration was caused not by the ecological and productivity potential (site class) of the soil for fir development, but primarily by the growth space, resulting from the application of single-tree selection or group selection systems. It was …

Turkish Journal of Agriculture and Forestry
Na^+/H^+ antiporters have been suggested to play important roles in salt tolerance in plants. English cordgrass (Spartina anglica) is a gramineous halophyte with very strong salt tolerance. It possesses salt glands in its stems and leaves, through which excess salt can be excreted. In this study, a vacuolar Na^+/H^+ antiporter homologous gene (temporarily named SaNHX1) was isolated from Spartina anglica by RT-PCR and rapid amplification of cDNA ends (RACE). Southern blot analysis suggested that there might be 2 or 3 copies of the vacuolar Na^+/H^+ antiporter genes in the English cordgrass genome. Northern blot analysis showed that the expression of …
