摘要:

Flora and vegetation of the Loppio lake (western Trentino, Italy). - The characteristics of the flora and the vegetation of the Loppio lake (western Trentino, Italy) are presented. The study point out the variation in species composition of the flora and vegetation after the lake was drying up in 1958; in fact 25 species of the 129 present before are desappeared and particularly are desappeared all hydrophytes.

摘要:

Purpose of the study is to find a faster and simpler way to identify the silver fir (Abies albaMill.) from Serra San Bruno (Catanzaro). A morphological and anatomical analysis comparing the Serra San Bruno provenance and the Vallombrosa provenance detected that the SSB provenance had a higher percentage of needles with pointed apex and with stomata on the adaxial side, a greater number of stomatal rows per band, a greater number of stomata per 1 mm segment and per mm2, a greater thickness of the mechanical tissue (epidermis and hypodermis) and the palisade parenchyma, and a smaller diameter of the resin ducts.

摘要:

Growth and development of Rhodymenia ardissonei J. Feldmann (Rhodymeniales, Rhodymeniaceae). - Rhodymenia ardissoneispores give rise in culture to a disc from which the young fronds develop. The annual development of this species in the world includes passage through different forms, among which the winter one is similar toRhodymenia phylloidesL'Hardy-Halos (1970); the autumnal forms is that described by Maggs& Guiry(1982) from Ireland asRhodymeniasp. on the coasts of Brittany and Ireland.

摘要:

On the culture of spores and the development of the thallus of Botryocladia chiajeana (Menegh.) Kylin (Rhodymeniales, Rhodymeniaceae). - The complete development ofBotryocladia chiajeanahas been studied in culture. Spore germination and sporeling development is of thediscalis mediatustype described by Inoh(1947). The hollow vesiculous branches filled with a mucilage derive from the spacing of the erect filaments which form the stipe. The authors compare this development of the thallus with that described for other Rhodymeniales.

摘要:

Carteria wettsteiniiSchiller (1913) has been isolated from Golfo di Napoli and investigated by means of electron microscopy which revealed micro-anatomical features characteristic of the genusTetraselmis. The species is commonly present in Golfo di Napoli during summer with cell numbers 102–106cells-litre−1, occasionally producing blooms of 107cells·litre−1.
