Abstract

Rare and endemic plant species represent important components of plant biodiversity which require protection to ensure their sustainable conservation. Cerastium banaticum (Rochel) Heuff. is such an endemic and rare species from Romania, for which the genetic variability of two natural populations was studied by SSR markers. Shannon’s information index revealed low levels of genetic diversity in both populations (I = 0.296). As the first attempt in a conservation program a reproducible micropropagation protocol was established starting from seeds, followed by multiplication, rooting, and ex vitro acclimatization. Among the various plant growth regulators tested the highest multiplication coefficient was achieved on a culture medium with 0.5 mg L-1 6-furfurylaminopurine (K) and 1 mg L-1 α-naphthaleneacetic acid (NAA). On this PGRs concentration a number of 26.6 shoots/individual explant with a mean length of 7.9 cm for new generated shoots was registered. The highest number of roots/individual initiated shoot was 2.6 and it was recorded on a culture medium with 0.5 mg L-1 2-isopentyl-adenine (2iP) and 0.1 mg L-1 NAA. The outdoor acclimatization was successfully performed in a specially designed rocky area in the ‘Alexandru Borza’ Botanical Garden, Cluj-Napoca (Romania).

Abstract

The article addresses the topic of the professional contacts between the renowned Polish histor-ian, Józef Andrzej Gierowski, and Romanian historians from academic institutions in Bucharest, Iasi and Chisinau. Following an analysis of the extant sources, it has been concluded that these contacts were the most intensive in the 1970s. They included participation in academic con-ferences, congresses and symposia, as well as private correspondence, e.g. with Veniamin Ciobanu from Iasi. In this particular case, the professional relationship evolved into a personal friendship. Józef Andrzej Gierowski’s recognisability among historians on a foreign academic forum attests to the fact that his achievements in research on the history of Central and Eastern Europe earned him considerable standing and respect among his peers.
