Thidiazuron-induced morphogenetic response in petiole cultures of Pelargonium x hortorum and Pelargonium x domesticum and its histological analysis.

摘要: The possibility of inducing somatic embryogenesis in petiole cultures two cultivars Pelargonium x hortorum and one cultivar domesticum using thidiazuron (TDZ) was investigated. Petioles were cultivated on a modified Murashige Skoog medium with different concentrations application periods TDZ. Regeneration achieved all TDZ treatments for highly variable. Shoots shapes embryo-like structures observed. Histological examination revealed that no embryos formed, regenerants had to be classified as shoots shoot-like or leaf-like structures. importance these results the classification regeneration induced by species propagation pelargoniums is discussed.
