SEED BURIAL EXPERIMENT FOR ALPINE PLANTS
Seed storage experiment was carried out for 28 alpine species in Northwest Caucasus. We tested seed germiability for fresh collected seeds, winter storage on soil surface and soil burial treatment (1, 2, 3 and 5 years). Most of the species showed higher germiability after one winter storage on soil...

Summary: | Seed storage experiment was carried out for 28 alpine species in Northwest Caucasus. We tested seed germiability for fresh collected seeds, winter storage on soil surface and soil burial treatment (1, 2, 3 and 5 years). Most of the species showed higher germiability after one winter storage on soil surface. Germiability of burial seeds decreased from one to five year sto-rage. Only two species (Leontodon hispidus, Senecio aurantiacus) germinated after 5 years burial in soils. Эксперимент с погребением семян 28 видов альпийских растений проведен на Северо-Западном Кавказе. Изучена всхожесть свежесобранных семян, всхожесть семян после зимнего хранения на поверхности почвы и всхожесть погребенных в почву на 1, 2, 3 и 5 лет семян. Всхожесть снижалась с увеличением срока погребения. После 5 лет погребения проросли семена только двух видов – (Leontodon hispidus, Senecio aurantiacus). |
