Gene Transfer in Woody Plants: Perspectives and Limitationseny has been demonstrated. Unexpected genetic variability may be associated with foreign gene transfer in plants. This variability may be a cause of concern in long-lived tree species, following foreign gene transfer. Perspectives and limitations of foreign gene transfer will be discussed in plants, in particular tree species.

Tissue Culture Studies on Mahogany Tree, ,appearance. Callus obtained from leaves were almost transparent and colorless. Experiments on . culture and micropropagation of mahogany suggest that mass propagation of this tree is possible using this method, particularly because of decline in natural populations.

Differential Norms of Reaction in Tissue Culture of Birch MS-medium (Murashige and Skoog 1962)..The results show, that under the applied conditions the genotypic effects have a stronger influence on the phenotype than the environmental effects have. They depend on the genotypes, so that at least one-sided separability of the genotypic from the environmental effects could be observed.

Antizyklone oder ein Hochdruckgebiet ist entsprechend ein Gebiet, in dem der Luftdruck allseitig zum Zentrum hin zunimmt. Beide Drucksysteme sind durch geschlossene, meist kreisförmige bis elliptische Isobaren gekennzeichnet. In Mitteleuropa liegt der Kerndruck der Bodentiefs i. allg. bei 990–1000

Dazu dienen Boden- und Höhenwetterkarten, Diagramme über die vertikalen Verhältnisse an einem Punkt oder längs eines räumlichen Vertikalschnitts sowie Zusatzinformationen, wie z. B. Radaroder Satellitendaten. Aus diesen Unterlagen entnimmt der Vorhersagemeteorologe die Ver
