A study was made of the stimulating effect of benzolinone (3-benzyloxycarbonyl-methyl)-2-benzothiazolinone in powder form (P) and its mixture with indole butyric acid (IBA), the biofungicide Supresivit and fungicide Captan 50 WP on the root formation of 17 species of ornamental plants, park and fruit woody species. Under the action of benzolinone, the yield of rooted cuttings in the category of ornamental plants amounted to 44.5% (in the Dianthus sp.) up to 83.7% (in Rosa canina), in the category of park woody species it was from l6.7 (in Magnolia stellata) to 100% (in Forsythia intermedia). In fruit trees...

Leaf samples from 12 peach cultivars (Prunus persica [L.] Batsch.) (Early Crest, May Crest, Flavor Crest,Sun Crest, Fayette, Katherina, Loadel, Andross, Everts, May Grand, Firebrite and Fairlane) grafted on four peach root-stocks were analyzed for their nutrient content. The analysis of variance for leaf nutrient concentrations indicated very significant effects and interactions among cultivars and rootstocks. The rootstock effect on the absorption of nutrient elements was higher for Ca, K, P, Mg, N, and lower for Cu, Zn, Fe, Mn, and B. Generally cultivars grafted on GF 677 had higher N, K, Fe, Cu and lower Zn, Mn, and B, while leaves from...

Of about 100 Lactuca species, there are only 22 represented in world gene bank collections. The description of morphological and other important features of wild lettuce accessions and a correct taxonomic ranging increase their potential successful utilization. A broad study of 22 wild Lactuca species, their morphology, anatomy, karyology, DNA content and isozyme variation, and a search of large number of literature sources (description keys, floras, monographs) provided a base for an elaboration of a descriptor set. This set consists of 88 descriptors and 24 of them are elucidated by figures. It provides a tool for Lactuca...
