** Botanic Garden “A. Fatu”, 7-9, Dumbrava Rosie Street, Iasi, Romania
Abstract: In order to assist the Romanian Government in fulfilling their obligations required to become a full member of the European Union, the Dutch Agency for International Business and Cooperation (EVD) developed a special project, focused on Habitat Directive plants, having as result a preinventory for a draft list of Natura 2000 sites (SCIs) for plant species. In this frame the Romanian botanists evaluated the existing lack of information concerning the plants distribution in Romania, the difference between national and internal approach and the requirements for well understand and document this group of taxa, very important for Habitat Directive implementation in Romania.

| CONSIDERATIONS REGARDING THE ALIEN
PLANTS FROM MOLDAVIAN FLORA (ROMANIA), DELIBERATELY INTRODUCED BY
* University of Agricultural Sciences and Veterinary Medicine Iasi, Faculty of Agriculture, 3, Mihail Sadoveanu Street, Iasi, Romania
Abstract: The most plant species cultivated in Moldavia (Romania) for various uses aren’t native in this territory. Their introduction by man, from various geographical regions, started long time ago, in ancientness, and now it is also in a continuous evolution. The most of these plants are met in crop only but a small proportion of them, escape from crops (they turn to wildness), becoming elements of the spontaneous flora. Such plants named hemerophytes can cause peculiar damages to the natural or anthropic invaded ecosystems and their knowledge represents an essential support in the rational management of the biological immigration and invasion. After consulting a great lot of bibliographic sources and based on the field observations of the author in the last years, it results for the Moldavian territory a number of 169 vascular hemerophytes, among which 21.3% have an invasive character, 15.4 % are naturalized ones, and 63.3% are only occasional escaped from crops. The paper gives informations about geographical provenance of these species; period, place and reason of their introduction; types of affected habitats; first mention in the wild, and their current spreading in Moldavia.

DALECHAMPII ASSOCIATION IN THE LOWER BASIN OF THE MOTRU RIVER
* The University of Craiova, The Horticulture Faculty, Biology Department, 15 Libertatii Street, 200583 Craiova, Romania
Abstract: From the geographical point of view, the Lower Basin of the Motru River lies in the western part of the Getic Piedmont, with the coordinates: 44055' north latitude and 23045' east longitude. The studied area covers 691 Km2. The physical-geographical position and the pedo-climatic particularities specific to the territory under research confer the vegetation a mosaic nature with a particular specificity, determined by the quite strong Balkan and sub-Mediterranean influences. With the territory under research located just on the line between the nemoral area (of the oak forests) and the floor of the hilly common oak (up to the sub-Carpathian Hills), we cannot talk about the presence of the acidophilus common oak forests, which is characteristic to the sub-Carpathian region. In this transition area, between the altitudes (200) 250 and 380 (402) m, we have identified mixed common oak forests, associated with Hungarian oak and Turkey oak, belonging to the association Potentillo micranthae-Quercetum dalechampii A.O.Horvát 1981 (Syn.: Potentillo micranthae-Quercetum (petraeae resp. dalechampii-cerris) A.O.Horvát (1956) 1959). The affiliation of these phytocoenoses to the above mentioned association is done according to its transition association nature, between the silvosteppe forests and the mesophyle, acidophilus forests in the sub-Carpathian area of Oltenia.

| GROWTH RATE TESTS FOR MATERNAL
DESCENDENTS OF PEDUNCULATE OAK (QUERCUS ROBUR L.)
* The Nature Reserve „Plaiul Fagului”, Republic of Moldova
Abstract: The growth rate of Quercus robur L. saplings obtained from the germinated acorns sowed in the autumn and spring was investigated. The growth rate of descendents obtained from the spring sowed acorns was revealed to be much higher than those obtained from the autumn sowing. The differences of their growth rate were significant and therefore those differences have a certain practical value. It was also demonstrated the importance of collecting the acorns formed in conditions that assure cross-pollination of trees (from polymorphic population). Saplings obtained from this population grew much faster than those obtained after self-pollination (in consanguine population). This phenomenon could be a consequence of partial splitting of heterozygote and accumulation of homozygote in posterity after self-pollination, factor that influence the growth of obtained genotypes. In consanguine population was observed the high level of genotypes variation, accompanied with a low level of some part of saplings viability and vigor. Slow growing of oak saplings determines the difficulties of their maintenance, especially during the first years of life. Thus, cross-pollination and spring sowing of the obtained acorns are the two factors that are important to take into account when we want to obtain viable and vigor descendents of pedunculate oak.
