In continuous studies regarding the conservation of the advantageous condition of the soil structure, the highland plantations that are surrounded by living waters have major importance where the erosion of the soil, nutrients and chemicals endangers the quality of the water and the living world of the waters. At the same time the extreme weather ...and dry summers of the past years have made it important to look for soil cultivation solutions and technologies that are capable of decreasing the evaporation of the soil, for enhanced conservation of soil moisture and to improve the soil structure that is required for the growth of healthy roots. In our experiment we have studied soil mulching with organic plant residue, by sods and the effect of the mechanical cultivation on the soil and on the grape through two growing seasons. From the studied treatments, the mulching with organic plant wastage showed the most efficient results from the point of view of the nutrient distribution in the grape and yield. It also had a positive effect on the soil structure and humidity.
Basil species are highly sensitive to exterior environmental conditions and its consequences lead to great economic and agronomic losses. In this research, a mutation method was optimized out for creating a new variety of Ocimum basilicum L., which could tolerate the extreme/extraordinary climatic circumstances or biotic stresses, such as fungal d...iseases. Fast neutron irradiation was performed on the Hungarian commercial variety seeds with doses of 5 to 60 Gray and grown into fully developed plants. Numerous phenotypical changes like deformed congestion, leaf mutation, and low growth occurred, especially at higher dosages. Then to confirm whether the plantlets had mutation or not, and to detect the molecular variation and relationship, fingerprinting profiles of the developed mutant regenerants and donor plant have been assessed using ISSR markers. 115 loci were yielded, ranging from 0.2 to 1.5 kb, out of which 110 loci were polymorphic in nature, representing 95.6% polymorphism. The most suitable primer to determine the genetic diversity within the Ocimum species was the UBC-856 with 0.42 PIC and 4.1 MI values.
