Fruiting biology of Staphylea pinnata l. (Staphylaceae) in the Republic of Moldova

Abstract

The study presents the results of the fruiting biology in the interaction with the environmental factors of the Staphylea pinnata L species, a rare species for the Republic of Moldova, protected by law (1998). At the European level, the species is included in the national red lists of Switzerland, France, the Czech Republic and Poland, while in Armenia and Ukraine, it is even included in the Red Cards with different degrees of endangerment. European bladdernut is a relict species with a fragmented distribution area and includes the Mediterranean, Central and East Europe regions. It grows under the canopy, in forest phytocenoses: of oak with lime and ash; of pedunculate oak with hornbeam. During the study, the morphometric parameters of the fruits and seeds of the european bladdernut were studied to determine the productivity of the species in different stations. The collected seed samples are to be preserved in the seed collection `Rare Plants of the Republic of Moldova`, within the research project `The safe conservation of the germplasm of rare plants from the Republic of Moldova` (24.80012.7007.08TC).
