The substratum influence on cutting's rooting of Taxus baccata.

Abstract

Taxus baccata is an ornamental tree, 3rd stature, with large-pyramidal crown and several stems. The truncks are covered with red scales, the scales takes of in plates. The wood of Taxus baccata is compact, strong and is of a great demand in caving. The shoots are green, the buds are oval, are green color, and are clumped to the top of the shoots. The leaves are 2-3 cm long, 0.15-0.2 cm broad, dark-green on the adaxial side, light-green on the abaxial side. The flowers are unisexual and the plants are dioic. The seed is ovoid with a hard and brown tegument, covered by a fleshly aryl, green at the beginning, becoming red. The aryl is eatable but the plant contains poisoning alcaloid named taxyn. Taxus baccata vegetates also in vegetated areas from plain, as well as in vegetated areas from hills and mountains. It is resistant on frost, drought and dust. In Romania the species exhibits a restricted spread is little spread, tha cause might be the absence of the planting material. To rise the efficiency of the vegetative multiplication by, we investigated the substratum influence on cuttings rooting.
