THE BIOSTIMULATOR REGLALG AS AN INDUCTOR OF PLANTS' VIABILITY AND VIGOR
(CEP USM, 2023) Dascaliuc, A.; Jelev, Natalia; Voineac, V.
By the definition for the biostimulator, Reglalg contains substances extracted from algae that stimulate the natural plant processes that improve their tolerance to environmental abiotic stress, nutrient-use efficiency, quantity, and quality of the crop. During several years of testing, it has been demonstrated that due to the beneficial influence of Reglalg on the vigor and viability of different plant species, the plants are also less affected by biotic stress factors. Due to these properties, the biostimulator Reglalg is a highly effective preparation for use in organic agriculture.
Influenţa deficitului hidric asupra germinării seminţelor unor genotipuri de grâu
(CEP USM, 2024-10-07) Jelev, Natalia
In order to determine the parameters that can be used as a rapid criterion for assessing drought resistance, the present investigation was carried out to evaluate six wheat genotypes, to the stress of drought induced by polyethylene glycol during germination and seedling growth. Seven parameters characterizing the germination processes were studied; germination energy, germination capacity, speed of germination, speed of accumulated germination, coefficient of the rate of germination, mean germination time, vigor index and two growth parameters; root length and shoot height were measured under the experimental conditions. The average comparison showed that the highest value for the majority were recorded for the genotypes Moldova 16, Moldova 614 and Lăutarii.
Phenotypic plasticity and plant resistance to abiotic stress
(CEP USM, 2024-10-07) Dascaliuc, Alexandru; Jelev, Natalia; Ralea, Tudor
The phenotypic plasticity of cultivated plants exceeds that characteristic of spontaneous plants. Concerning this, the question arises as to why a commensurate level of genome volume did not accompany the high level of crop plant phenotype changes. More and more data are emerging, demonstrating that, due to the rapid activation of phylogenetic adaptation systems stored in the genome, phenotypic plasticity generates non-random adaptation changes. We present the results of assessing the resistance of plants to the action of extreme temperatures and the influence of the biostimulator Reglalg on the viability, resistance, plasticity, and productivity of wheat and pedunculated oak plants.
