Efficiency of Switchgrass (Panicum virgatum L.) Cultivation in the Ukrainian Forest-Steppe Zone and Development of Its New Lines

Background:

Switchgrass (Panicum virgatum L.) is a promising C4-photosynthetising perennial grass and an important energy crop. It is resistant to drought, cold and winter frost, endures flooding and shows high performance at minimal energy consumption for cultivation.

Methods:

The purpose of the work was to develop and introduce high-yielding genotypes of switchgrass and develop effective cultivation technologies for the Forest-Steppe zone of Ukraine. The objective of the study was to evaluate the introduction potential of switchgrass, to establish biologically productive parameters and energy values of different genotypes and the effectiveness of cultivation techniques in the specific geo-climatic zone of Ukraine. To achieve the objectives, a wide range of introductory, biological-morphological, breeding-biotechnological, and agronomic methods have been used.

Results:

The gene pool of P. virgatum was collected (33 accessions), ten of which have been investigated, including both introduced genotypes and newly developed breeding lines. The bio-morphological, ecological features, the biochemical composition of plants have been evaluated. The productivity of the above-ground biomass and seeds, as well as the energy value of plants, has been evaluated. High-performance forms with specified yield parameters, biomass sugars, total energy and biofuel output per unit area have been determined.

Conclusion:

A new variety of P. virgatum (cv. Zoriane) has been introduced for cultivation. Among the accessions of newly developed genotypes, the most productive lines have been identified. New efficient technologies have been developed to increase the yield potential of switchgrass as a source of raw materials for biofuel production.

Induction of Bacterial Canker Resistance in Tomato Plants Using Plant Growth Promoting Rhizobacteria

Yuliya Kolomiiets, Ivan Grygoryuk, Artur Likhanov, Lyudmila Butsenko, Yaroslav Blume

Background:

By inducing the production of inhibitory allelochemicals and mechanisms of systemic resistance Plant Growth Promoting Bacteria (PGPB) help plants to cope with stresses.

Materials and Methods:

In this study cell suspensions of Bacillus subtilis, Pseudomonas fluorescens or Azotobacter chroococcum were used to test the efficacy of these PGPB in inducing resistance in tomato (Lycopersicon esculentum Mill) against Clavibacter michiganensis subsp michiganensis, a bacteria known to cause canker disease. To test this hypothesis, seedlings of Chaika variety, characterized by short growing, early-ripening, high productivity and resistance against fusarium and the C. michiganensis strain ІZ-38 isolated in Kyiv were employed.

Results and Conclusion:

The use of cell suspensions of the PGPB B. subtilis, A. chroococcum or P. fluorescens induced an increment in the resistance of tomato plants against the causative agent of bacterial canker (C. michiganensis subsp. michiganensis) by 42–50%. PGPB in fact promoted in C. michiganensis infected tomato plants: i) the accumulation of chlorophyll a and b and carotenoids; ii) the thickening of the upper and lower epidermis of leaves; iii) the deposition of biopolymers with protective properties in epidermal cells; iv) the activity of the peroxidase enzyme and v) the net productivity of photosynthesis.
