Blüte Des Diptam |
Description |
500px provided description: In the summer months, the whole plant is covered with a kind of flammable substance, which is gluey to the touch, and has a very fragrant, lemony aroma; but if it takes fire, it goes off with a flash all over the plant. The name "burning bush" derives from the volatile oils produced by the plant, which can catch fire readily in hot weather. The volatile oils have a reputed component of isoprene. The leaves have a bitter and unpalatable taste. Despite the lemon-like smell, the plant is acrid when eaten. All parts of the plant may cause mild stomach upset if eaten, and contact with the foliage may cause photodermatitis. Die Frucht ist eine Kapsel. Bei viel warmem Wind trocknen die Fr?chte ein. Dabei rei?en die Fruchtschalen auf, rollen sich ein und schleudern den kugelf?rmigen, etwa 4?mm kleinen Samen heraus. Da der Diptam meist klonal in Gruppen w?chst, kann man das manchmal gemeinsame Knallen der Fr?chte im Sommer h?ren. Die Samen k?nnen bis etwa f?nf Meter weit weggeschleudert werden. Zur Reifezeit geben die Dr?sen der Fruchtst?nde so viel ?therisches ?l ab, dass die Pflanze schon von weitem gerochen werden kann. Der Duft des Diptams kann durch Mischung von Vanille- und Zitronenaroma nachgeahmt werden. Die vor allem in der dr?sigen Beborstung enthaltenen Furanocumarine sind phototoxische Stoffe, die bei Ber?hrung mit der Haut diese gegen Sonnenlicht sensibilisieren und bei nachfolgender Besonnung zu schweren, oft langwierigen verbrennungsartigen Verletzungen f?hren k?nnen. Die ?therischen ?le enthalten die extrem fl?chtige und hochentz?ndliche Fl?ssigkeit Isopren, deren D?mpfe schwerer als Luft sind. In der Reifezeit k?nnen die freigesetzten Isopren-D?mpfe an windstillen Tagen durch eine Z?ndquelle unterhalb der Bl?tenrispe entz?ndet werden, worauf die Feuerfront schnell die Bl?tenrispe emporl?uft und dann erlischt. Die Pflanze nimmt dabei keinen Schaden. An extrem hei?en Tagen k?nnen sich die D?mpfe auch selbst entz?nden. Erkl?rt wird dies durch die Brennglaswirkung bei Tr?pfchenbildung. In der D?mmerung kann man bei Windstille und gro?er Hitze an der Pflanze kleine blaue Flammen sehen.
