Phases of the phenological of Wistaria floribunda

Phases of the phenological of Wistaria floribunda (Willd.) DC are shown to disclose the perspective dates of the vegetation embracing the phases of flowering (March-April), of ripening of the fruits (October) and of having complete foliage (April-October). The first course of development or ontogeny, the germination, covers a period of 10 – 12 days; the growing phase embraces a period 2 – 3 years and development to maturity from 3 to 5 or 6 years, before the generative phase begins. A huge quantity of seeds is required in the fields in comparison to the cultivation in botanical gardens, where only 50 – 70 % of this demand is needed

Degree of Adaption of Lianas (Parthenocissus quinquefolia (L.) and Campsis radicans (L.)) to the Environmental Conditions of Towns

Results of anatomic investigations are discussed, being carried out at leaves of lianas (Parthenocissus quinquefolia (L.) and Campsis radicans (L.)), growing under environmental conditions of towns. It could be found from the result, that xerographic phenomenons are reflecting the environmental conditions in towns. The effects of environmental pollution can be found at necrotic cells in the mesophyll of leaves. Demages of the leaves could be found by only visual investigations of the leaves
