This paper reports the effect of modified nutrient media on biotechnologically growing rootstock plants (Gizella – 5 and VSL – 2) at the stages of introduction and grafting. Murashige and Skoog medium was modified by adding 25 mg/l Chelate-Fe and 500 mg/l of Ca(NO)3 to the basic nutrient at the stage of introduction of the plant. At the grafting stage 0.1 mg of 6-Benzylaminopurine (6-BAP) was added to Murashige and Skoog, where the effect of regeneration was 2 times higher than in experimental control. The results obtained prove that modified Murashige and Skoog medium is to be the best nutrient media for root-plant introduction and regeneration processes in Vitro followed by Chelate-Fe, Ca(NO)3 and 6-BAP respectively.
The transition to a highly productive and environmentally friendly agricultural sector, the development and implementation of systems for the rational use of mineral fertilizers for obtaining safe and high-quality, including functional, food products is one of the main tasks allocated by the President of the Russian Federation V. V. Putin. Due to this decree, the theory of mineral nutrition has received rapid development in recent decades within scientific and technological progress in the field of analytical chemistry and physics, molecular biology, and genetics. Information on various physiological and biochemical functions of plant nutrients has been obtained, and the regularities of the distribution of elements in various parts of plants and fruits (berries) have been also generalized. The main forms of nutrients in the soil and the factors determining the bioavailability of macro and micronutrients have been identified. The aim of this research paper is to produce a biodegradable fertilizer where Azofoska Universal (N16: P16: K16) was uniformly coated within layer size by water-soluble biopolymer through continuous flow reactor V-star. The obtained samples were further tested and compared to well-known American analog slow-released fertilizer TAGROW on berry plants under greenhouse conditions within, berry root plant volume, stress resistance of plants, yield, the resulting fruits were studied for sugar levels using an RHB-32ATC refractometer. Moreover, infrared spectroscopy data for obtained biopolymer coated Azafoska Universal is illustrated in this research.
This research project is about the advantages and disadvantages of using white LED bulbs and fluorescent lamps when growing fruit rootstocks (VSL -2 fruit rootstock) in Vitro. The comparative analysis of using two different lamps will be based on subject of plant growing, development of root system and green leaf pigmentation. Moreover, pros and cons are summed up in terms of the resulting plant yield, where LED bulbs and fluorescent lamps were used within different illumination.
The aim of the work was to see if the direction of angular momenta in atoms is quantised. In order to do it, a beam of atoms is split, and deflected because of interactions between atomic dipole moments and an externally applied magnetic field. In which case, the angular momenta in atoms is definitively quantised. Firstly, the detector was checked and then the operation of the detector was characterised; secondly, the beam was detected and characterised with residual magnetisation minimised; thirdly, the beam was detected and characterised with magnetic field present. The sample used to determine the magnetic moment was Potassium. The Bohr’s magneton constant value was found to be (9.22±0.7)*10−24 J/T. The answer is lower than the nominal value but lies within the expected error range. This proved the accuracy of the work done and proved the quantisation of the angular momentum, since it proved the presence of magnetic moment.
