    EFECTUL PĂSTRĂRII ÎNDELUNGATE A RELEVEELOR DE SOL ÎN CONDIŢII DE LABORATOR ASUPRA COMPONENŢEI ALGOFLOREI EDAFICE DIN PĂDURILE DE FAG
    (CEP USM, 2009) Şalaru, Victor; Şalaru, Vasile; Melnic, Victor
    The analysis of brown soil on which has been kept in the laboratory conditions for 15-18 years and helped us to distinguish 22 species of algae in comparison with these 48, which was established in the first period of investigation (1984-1987 years). The algae community which was established in the years 2000-2002, are characterized by the predominance of representatives green algae fillum. A long preservation of soil samples in the laboratory for 15-18 years, is contributing to the disapperence of algae from Bacillariophyta fi llum, decreasing green and from Xanthophyta fillum algae diversity, which decreases the number more than twice with a lesser extent it influences on the Cyanophyta fillum. The most resistant were found to be Cyanophyta fillum fi laments form, which are characterized by the presence of a mucilaginous sheath which is well pronounced.

    GRUPELE ECOLOGICE DE ALGE EDAFICE DIN SOLURILE UNOR TIPURI DE AGROFITOCENOZE
    (CEP USM, 2008) Şalaru, Victor; Şalaru, Vasile; Chicu, Neli
    Dans le présent article on analyse les résultats des recherches consacrées à l’évidence des groupes écologiquesdes algues édaphiques les plus fréquentes chez les cultures agricoles par rapport aux écobiomorphes algales descommunités d’algues édaphiques des sols plantés de différentes cultures agricoles. On a constaté que des écobiomorphes comme les formes algales du type: X, Ch, C, CF, P, H et B étaient communes pour les types d’agrophitocénoses étudiés;à la fois pour chacune d’entre elles des traits spécifiques ont été dépistés.

    PARTICULARITĂŢILE STRUCTURII TAXONOMICE ŞI ALE ECOBIOMORFELOR ALGELOR EDAFICE DIN VEGETAŢIA DE STEPĂ DUPĂ O PERIOADĂ DE PĂSTRARE ÎNDELUNGATĂ ÎN STARE DE ANHIDROBIOZĂ
    (CEP USM, 2012) Şalaru, Victor; Melnic, Victor
    The paper presents the results obtained in the years 2000- 2002 of analysis of edaphic algal communities and their life forms witch were contained in soil samples collected in the steppe vegetation in the years 1894-1987 and were kept in laboratory able to desiccation. There was a determinate taxonomic structure of comm unities of algae and the life forms with germination capacity after a desiccation period of 15-18 years.
