Abstract
În articol sunt redate particularităţile structurale ale algoflorei edafice din serele s. Chiştelniţa. Structura taxonomică
este constituită din 53 de specii şi varietăţi intraspecifice de alge, care aparţin la 31 genuri, 22 familii, 16 ordine şi 7 clase,
dintre care cea mai înaltă diversitate au clasele Hormogoniophyceae – cu 16 specii şi Xanthophyceae – cu 14 specii. Caracteristica
ecologică a algoflorei demonstrează predominarea ecobiomorfelor P, care sunt lipsite de heterociste şi răspândite
printre particulele de sol sau se dezvoltă la suprafaţa lui. În algoflora solurilor au fost depistate 4 specii ce aparţin
ecobiomorfei CF şi sunt azotfixatoare: Anabaena sp., Cylindrospermum licheniforme (Bory.) Kütz., Nostoc linckia
(Roth.) Born. et Flah. şi Nostoc sp., care, în conformitate cu datele din literatura de specialitate, reprezintă tulpini de
perspectivă pentru promovarea agriculturii ecologice
n this article are presented structural features of edaphical algal flora of greenhouses from village Chistelnita. Taxonomic structure consists of 53 species and varieties of algae belonging to 31 genera, 22 families, 16 orders and 7 classes, of which the highest diversity have Hormogoniophyceae an d Xanthophyceae classes, with 16 and 14 species. Ecological characteristics of algal flora demonstrates th e predominance of P ecobiomorphic, which are devoid of heterocyst and spread through the particles of ground or on the surface of it. In soils algal flora were discovered four species belonging to CF ecobiomorphic and they are nitrogen fixing: Anabaena sp., Cylindrospermum licheniforme (Bory.) Kutz., Nostoc linckia (Roth.) Born. et Flah. and Nostoc sp., which according to data from the literature, is promising strains for promoting organic farming.
