Nouvelles observations sur l'hybride intergénérique expérimental ×Agroelymus PielleiA. de Cugnac

A framework to identify constraints to post-extinction recovery of plant species—Application to the case of Bromus bromoideus

“…Soon after its discovery, B. bromoideus generated a lot of enthusiasm among botanists, with the result that several botanical gardens wanted to have it in their collections. In the 19 th century, the species was grown in and distributed by 35 botanical gardens scattered all over Europe (de Cugnac, 1936). Over the years, due to a gradual decrease in interest in the plant, the number of institutions cultivating this species dropped to 5 in 1936.…”

“…We do not know the number of regeneration cycles, but it is supposed to be very high. According to de Cugnac (1936), no less than 35 botanical gardens throughout Europe cultivated and distributed B. bromoideus at some point during the 19th and 20th centuries. Of these, about ten have distributed the species without significant interruption for at least 20 years.…”
