Abstract:

The article discusses the results of the use of root formation stimulants in the green propagation of four varieties of juniper: juniperus scopilorum 'Moonglow', juniperus squamata 'Blue Star', juniperus communis 'Hibernica', juniperus virginiana in a tree-decorative nursery. Rooting was carried out in summer cultivation facilities under conditions of artificial fog. Four serial production stimulants were tested: Kornevin, Heteroauxin, Root, Zircon. Statistical processing of data showed that the use of all considered stimulants allowed us to obtain results other than control. This suggests tha

Abstract:

In recent years, the demand for effective and low-toxic stimulators of rhizogenesis, which are used in microclonal propagation of plants, has been increasing in Ukraine. One of the promising directions in the search for effective compounds is molecular modeling based on known natural and synthetic compounds. The development of new highly effective and low-toxic biologically active compounds is largely based on derivatives of nitrogen-containing heterocycles, and quinoline occupies a significant place among them. Modern methods of chemometric analysis make it possible to find certain regulariti

Abstract:

The rooting of rootstocks is considered a critical point in the production of high-quality grapevine planting material. To maximize the cutting rhizogenesis process, plant hormones, such as auxins, are used for the development of adventitious roots. In addition, some groups of biostimulant have as their main role the development of root system, ensuring good growth of the plant aerial part. However, research using algae extract-based biostimulants in vegetative propagation of vine rootstocks is scarce. In this sense, the objective of this work was to evaluate the use of the biostimulant based

More than 100 explants were used to stimulate the indirect and direct morphogenesis. Mesophilic explants were cultured on the MS nutrient medium containing auxin to callus proliferation (2 mg/L NAA, 1 mg/L BA).

ABSTRACT When surface-sterilized spores of the arbuscular mycorrhizal fungus (AMF) Glomus intraradices Sy167 were germinated on agar plates in the slightly modified minimum mineral medium described by G. Bécard and J. A. Fortin (New Phytol. 108:211-218, 1988), slime-forming bacteria, identified as Paenibacillus validus, frequently grew up. These bacteria were able to support growth of the fungus on the agar plates. In the presence of P. validus, hyphae branched profusely and formed coiled structures. These were much more densely packed than the so-called arbuscule-like structures which are fo

Abstract:

Bark necrosis (BN), described and first studied in Côte d'Ivoire in the 1980s (2), affects most modern rubber plantations (i.e., grafted trees with high-yielding clones, intensive exploitation due to tapping frequency, and use of Ethrel as a yield stimulant) worldwide with a wide range of severity across sites. While previous (3) and recent (4) etiological analyses remain inconclusive, environmental factors were shown associated with BN. Numerous epidemiological surveys conducted in various African and Asian plantations on recently tapped blocks (less than 10-year-old trees) revealed the nonra

Abstract:

Tissue and cellular plant in vitro breeding is a promising trend that complements and accelerates traditional breeding. Stress modelling under strictly controlled conditions on selective media allows for selection based on resistance to negative environmental factors (including drought and salinity), and preserving and cloning in vitro of selected variants with the desired traits. For forest woody plants, issues related to the adaptation of tolerant genotypes to ex vitro conditions have not been sufficiently studied. This research examines the adaptation features to non-sterile soil conditions

One of the important groups of roses are ground cover roses, used not only as garden plants but also in urban green areas for covering scarps and hill slopes. Roses are mostly propagated in vitro and by budding, grafting, and cuttings however, the latter is feasible only in certain rose groups. To hasten the production of plant material, preparations that stimulate rhizogenesis are used, which are based mainly on auxins and enhance the growth of adventitious roots in cuttings. Other substances capable of stimulating plant growth are biostimulators, which can be an alternative to rooting formul
