Grapevine genotypes with potential for reducing the carbon footprint in the atmosphere and cultivation in a biological system
Abstract
The concentration of CO2 in the atmosphere is increasing from year to year. Taking into account the calculations of the greenhouse gas inventory, it was found that approximately 70% of CO2 in the atmosphere is absorbed by vegetation (forests, agricultural land, etc.). In the Republic of Moldova, agricultural land constitutes 75% of the total area of the country. The use of agricultural land with genotypes of agricultural plants that have a high potential for capturing CO2 from the atmosphere would significantly contribute to reducing the volume of this gas in the atmosphere. The use of agricultural land with genotypes of agricultural plants that have a high potential for capturing CO2 from the atmosphere would significantly contribute to reducing the volume of this gas in the atmosphere. The purpose of the study is to determine the capacity for absorbing carbon from the atmosphere by grapevine genotypes, using the light saturation curve method for photosynthesis. At the same time, it allows us to identify plant genotypes resilient to climatic factors with the possibility of cultivation in a biological system. The interspecific grapevine genotypes (Vitis vinifera L. ssp. sativa D.C. x Muscadinia rotundifolia Michx.) were used as the object of study: Amethyst, Alexandrina, Augustina, etc. and the intraspecific grapevine genotypes (Vitis vinifera L. ssp. sativa D.C.): Muscat of Alexandria, Sauvignon, Cabernet, etc. Using the light saturation curve method for photosynthesis, it was found that the interspecific genotypes: Amethyst, Alexandrina, etc. have a CO2 absorption capacity from the atmosphere twice as high as the intraspecific grapevine genotypes: Muscat of Alexandria, Sauvignon, Cabernet, etc. At the same time, the interspecific genotypes Amethyst, Alexandrina, etc. allow cultivation in a biological system without the use of phytosanitary products for the prevention and control of diseases and pests.
