A Possible Mode of Action of Methyl Jasmonate to Induce the Secondary Abscission Zone in Stems of : Relevance to Plant Hormone Dynamics.

Plants can react to environmental stresses through the abscission of infected, damaged, or senescent organs. A possible mode of action of methyl jasmonate (JA-Me) to induce the formation of the secondary abscission zone (SAZ) in the stems of was investigated concerning plant hormone dynamics. Internode segments were prepared mainly from the second or third internode from the top of plants with active elongation.

Development and Characterization of Bioactive Polypropylene Films for Food Packaging Applications.

Bioactive polypropylene (PP) films with active agents) presence for food packaging application have been prepared and characterized. The novel modified PP films were obtained via PP/additives systems regranulation and cast extrusion. The influence of two types of plasticizers (natural agents as well as commercial synthetic product) and bioactive additives on final features, e.

The Simple Method of Preparation of Highly Carboxylated Bacterial Cellulose with Ni- and Mg-Ferrite-Based Versatile Magnetic Carrier for Enzyme Immobilization.

The bacterial cellulose (BC) is a versatile biopolymer of microbial origin characterized by high purity and unusual water and material properties. However, the native BC contains a low number of functional groups, which significantly limits its further application. The main goal of its effective modification is to use methods that allow the unusual properties of BC to be retained and the desired functional group to be efficiently introduced.

Production of Homozygous Red Beet (Beta vulgaris L. subsp. vulgaris) Plants by Ovule Culture.

Hybrid varieties dominate the red beet market. The breeding process necessary to produce these cultivars is very difficult and time consuming. The application of in vitro gynogenesis can reduce the time needed to produce the corresponding homozygous pure lines to a few months.

Production of Homozygous Carrot (Daucus carota L.) Plants by Anther Culture.

Carrot is a vegetable of increasing economic importance. New hybrid cultivars are constantly required to meet the changing market needs. The application of anther culture significantly shortens the difficult and long-lasting breeding of carrot.
