Abstract: In this paper it is analysed the vegetative organs (the stem and the leaf) on the transversal and superficial sections of the folowing woody species: Colutea arborescens L., Coronilla emerus L. ssp. emeroides (Boiss. et Sprun.) Hay, Prunus tenella Batsch., Paliurus spina-Christi Mill., Ziziphus jujuba Mill.
It is evidenced some structural peculiarity which are diagnostical importance: in the stem, the structure of the periderm, of the pericycle and of the vascular tissue (the size and the shape of the woody vessels, the presence of the woody parenchyma); in the leaf, the petiole contour in transection, type of the trichomes; the presence of the secretary cells in the epidermis and the mesophyll structure.

Abstract: Testing in vitro the biological action of some fungicides for seed treatment on the fungus Ph. occulta in the Laboratory of Mycology at R.I.P.P. Bucharest it was concluded that the most toxic against the pathogen were the products: Bavistin DF, Konker, Curzate Manox, Tiramet 60 PTS, Tiracarb 60 PTS, Tirametox 90 PTS, followed by Gammavit 85 PSU, Sancozeb 80 WP, Ronilan DF and Sumilex 50 WP.
It has been established the in vitro relationships between the fungus Ph. occulta and various taxa of saprophytic fungi (Trichoderma, Gliocladium, Trichothecium, Coniothyrium, Epicoccum, Verticillium, Sordaria), with a view to selecting strongly antagonistic isolates showing capacity of biological agents for controlling the pathogen, test having priority in special literature. Only Trichoderma viride isolates and mutants and Sordaria fimicola proved a strong antagonistic capacity against the test-fungus Ph. occulta.

Abstract: The paper presents a semi-ruderal vegetal association edified by Daucus carota and Picris hieracioides species; this association hasn’t yet been cited from our country until now; this is known from some central-European countries, under the name Dauco-Picridetum hieracioides (Fab. 1933) Görs 1966. We have identified this association in the semi-ruderal habitats from Iasi and Cotnari vineyards (Iasi county).

Abstract: The psammophytic vegetation from the Tecuci Plain (Galati county) is presented in this paper. This kind of vegetation is represented, in that area, by eleven vegetal associations, distributed on the sandy soils in the Southern part of Moldavia region of Romania. All of these associations were analysed from floristical, phytocoenological, live’s forms, and phytogeographycal points of view. The floristic composition of psammic associations is influenced by the penetration of the species belonging to the Festuco-Brometea class.

Abstract: There is described a new association for the vegetation of Danube Delta. The dominant species in this association is Centaurea pontica Prodan & E. I. Nyárády, as an endemic one for the Romanian flora. All the phytocoenoses of this association are settled down in the ruderal places, on river-maritime sands, moderately salted and light nitrophylous. The characteristic species for this new association are Centaurea pontica and Plantago coronapus . The halotype of the association is the releve no. 6.

Abstract: Further on our geobotanical investigations upon Cernovca River Island (Danube Delta Biosphere Reserve), we are presenting now other twenty-seven vegetal associations. All of these associations can be alloted to the ruderal vegetation, halophytic vegetation, meadow vegetation, and bush vegetation. These types of vegetation were installed as a human influence over the natural succesion, resulting thus a secondary change of the vegetational cover.

Key words: secondary succesion, deflected association, ruderal association, halophytic associations, meadow associations, bush associations.

Abstract: The paper present 5 collections of decorative plants which have a small attack of phytopatogens in cultural conditions from Ornamental Department of Jassy Botanical garden. These collections are unique because of their size and their scientific value. They have 709 taxas (92 taxas – Begonia L. Collection, 500 taxas – Chrysanthemum L. Collection, 30 taxas – Cucurbitaceae B. Juss. Collection, 88 taxas Pelargonium L. Hérit & Ait. Collection, 7 taxas – Zantedeschia (L.) Spr. Collection).
We found only 14 phytopatogens from the 40-s which are cites by literature being parasite on our taxas.
For Begonia, the literature cites 8 phytopatogens (3 micromycetes, 2 bacterias, 2 viruses) but we found only Oidium begoniae Putt, Agrobacterium tumefaciens (E.F. Smithrand) Towsend and Lycopesicum virus 3.
In Chrysanthemum collection, we found only 8 phytopategens from the 29-s cites by literature. The phytopatogens (find by us) are: Erysiphe cicoracearum D.C., Septoria chrysanthemella Sacc., Alternaria chrysanthemi (only in some years), Fusarium chrysanthemi Litt (some years), 4 viruses in latency.
In Cucurbitaceae Collection, we didn’t find any phytopatogens, but the literature didn’t cites anything too.
For Pelargonium, the literature cites 13 phytopatogenes (4 viruses, 6 bacterias, 3 mycromicetes) but we found only 2 micromycetes (Puccinia pelargoni zonale Doige, Pythium de barianum Hesse) and one viruses in latency (cucumber mosaic virus).
Zantedeschia collection wasn’t attacked by phytopatogens.
Because of cultural technology, warning and control methods, our collections have a small attack of phytopatogens.

Key words: phytopatogens, decorative plant colections.
