In the past, members of Cactaceae family were mostly propagated by seeds or vegetatively cuttings and grafting. Seeds, however, do not guarantee genetic stability and, in case some cacti, are difficult to obtain, their germination rates low, they need be stored for a long time specific light temperature conditions. Traditional vegetative reproduction vivo, on other hand, may less efficient insofar as limited number plants can obtained. Major issues associated with traditional propagation...

Echinacea purpurea (L.) Moench is a plant species important for the phytopharmaceutical industry and in horticulture. Currently, there lack of standardized material with an increased content secondary metabolites purple coneflower. The following research meets expectations industry, as new selected lines coneflower were micropropagated by somatic embryogenesis. analyzed both terms main High Performance Liquid Chromatography (HPLC), well genetic stability within line distance between using...

Abstract Random amplified polymorphic DNA (RAPD) markers were used to study the molecular characterization of 10 new radiomutants chrysanthemum. The original cultivar ‘Richmond’ differed in genetic distance from its Lady group mutants. analysis similarity indices revealed low diversity within radiomutants. dendrogram obtained after cluster separated cultivars as a that ‘Richmond’. cultivars, derived one by radiomutation, could be distinguished each other using RAPD only single primer or sets...

Having produced the embryos of cactus Copiapoa tenuissima Ritt. forma monstruosa at globular stage and callus, we investigated effect abscisic acid (ABA) in following concentrations: 0, 0.1, 1, 10, 100 μ M on successive stages direct (DSE) indirect somatic embryogenesis (ISE). In process also a combined ABA (0, 1 M) sucrose (1, 3, 5%). The results showed that low concentration (0‐1 stimulates elongation number correct embryogenesis, while high (10–100 growth inhibition turgor pressure loss...

Strawberry and wild strawberry are among the most popular horticultural crops. Due to development of soilless cultivation systems, whole-year production these economically important fruit crops is achievable even in countries with temperate climate. However, responses (Fragaria × ananassa Duch.) vesca L.) microclimate conditions greenhouse gutter autumn–winter season Poland have not been yet determined. The aim this study was analyze physiological, biochemical, biometrical two cultivars...

Cacti are important in agricultural economies and one of the most popular horticultural plant groups. The genus Astrophytum is valuable desirable cacti for growers collectors around world. By selecting appropriate breeding methods to induce variations combination with modern biotechnology tools rapid change detection, it possible meet challenges world creating new variability plants. However, there exists a lack research concerning impact ionizing radiation on cacti. aim study was assess...

Identification of cultivars is essential both in breeding and to settle cultivar disputes. The purpose the study has been examine identities based on absorption spectra plant pigments confirm a genetic stability with SCoT RAPD molecular markers new Polish lines Chenopodium quinoa Willd. Spectral analysis extracted from inflorescences gives an opportunity identity identification 'Faro' 'Titicaca' their lines. effective method confirming it should be used practice for or Analysis indicated by...

Cactaceae are a significant group of ornamental plants in the horticultural market. In present study, X-rays were used for first time to induce mutational changes cactus Copiapoa tenuissima. The aim this study was assess genetic variability seedlings exposed vitro X-ray irradiation at doses 0, 15, 20, 25, and 50 Gy (radiation from 5 min 13 s 17 22 s) by morphological analysis, spectrophotometric evaluation plant pigment content, confirmation level using SCoT (start codon targeted) markers....

Background. The Astrophytum and Frailea genus are very important cacti for horticultural production collectors over the world. problem is their similarity at seedling or cutting stage. Additionally many of cactus species endangered in natural habitats require protection. aim study was to develop a reliable system molecular markers based on multiple loci genomes species. Material methods. seeds all (or shoot fragment A. caput-medusae) were surface sterilized then grown under vitro conditions...
