Luxuring

The black alder shown here forms luxuriant hybrids with the gray alder

From luxuriate one speaks in hybrids when they surpass the breeding position at desired characteristics, the two parent species. Such characteristics can be productivity, vigor or other properties. One then speaks of the heterosis effect . An example of luxuriant growth is shown by the hybrid Alnus incana × Alnus glutinosa between gray alder and black alder , which grows 16% higher and shows a 45% larger diameter at the chest height than the gray alder and 12% higher and 33% stronger than that Black alder.
