Propagating Liriodendron tulipifera L. (Magnoliaceae) from seeds for introduction trials in the dendrology department of N. V. Tsitsin Main Botanical Garden RAS

Abstract

The seeds of Liriodendron tulipifera L. were collected from cultivated plants in Europe and Moscow for the purpose of collection replenishment in the arboretum of N.V Tsitsin Main Botanical Garden, RAS. In order to get seedlings we have specialized and tested a method of short stratification cycling and also used a standard procedure of sowing in containers combined with natural cycles of warm and cold conditions. Two of four samples of seeds exposed to short stratification cycling yielded a number of germinations in a month. This phenomenon complements the known literature data concerning the type of dormancy in the seeds of this species, being also of a practical value for its propagation.
