Effect of salinity and Ramsey rootstock on ion concentrations and carbon dioxide assimilation in leaves of drip-irrigated, field-grown grapevines (Vitis vinifera L. cv. Sultana)

Carbon dioxide (CO2) as one of the main factors driving climate change is known to increase grapevine growth and yield and could, therefore, have an impact on the fruit quality of vines. This study reports the effects of elevated CO2 (eCO2) on berry development and bunch structure of two grapevine cultivars (Vitis vinifera L. cvs. Riesling and Cabernet Sauvignon) within the VineyardFACE (Free-Air Carbon Dioxide enrichment) experiment, using must analysis and non-invasive fluorescence sensor technology. Berry development was examined on five dates over three consecutive years by analyzing total soluble solids (TSS), pH, total acidity, organic acids, nutrition status, and non-invasive Multiplex measurements. Before harvest, secondary bunches were collected to examine bunch and berry parameters. Results showed that eCO2 had little impact on berry composition of Riesling and Cabernet Sauvignon during berry development, which could be related to bunch structure or single berry weight within single seasons. Elevated CO2 (eCO2) did not result in modified TSS accumulation during ripening but was directly related to the chlorophyll index SFR_R. Higher single berry weights (SBW), higher malic acid (MA), and lower tartaric acid (TAA) were examined at some stages during development of berries under eCO2 levels. Our study provides evidence that eCO2 did alter some bunch and berry parameters without a negative impact on fruit quality.

Quantitative Content

The article discusses the use of supercritical fluid extraction in the technology for the isolation of resveratrol, a phenolic compound found in Vitis vinifera L. A technology was developed for obtaining the sum of polyphenolic compounds with a quantitative content of resveratrol. As a raw material for the production of the substance, Vitis pomace was used after the production of wine and juice, which makes it possible to introduce complex processing of plant raw materials. For the first time, by the method of carbon dioxide extraction, the conditions for the isolation of resveratrol from Vitis pomace raw materials of the Kazakhstani varieties Saperavi and Cabernet were optimized. The influence of pressure (from 10 to 35 MPa), duration (from 60 to 180 min), temperature (from 50 to 70 °C) was studied when optimizing the extraction mode. The quantitative content of resveratrol in carbon dioxide extracts was determined by high-performance liquid chromatography( HPLC). The optimal parameters for the extraction of Vitis vinifera L. pomace (pressure, duration, temperature) were established, which provide a relatively high content of resveratrol in the extracts.

Selection Of

This study reveals that morphogenesis of grapevine plants (Vitis vinifera L.) produced in vitro under carbon dioxide enriched atmosphereis largely determined by the morphogenetic pattern of vitroplants on which microcuttings were harvested. The presence of tendrils on shoots or shoot parts from which microcuttings were made was essential to obtain a high percentage of adult vitroplants with ternary sequence of tendrils. Therefore, under in vitro culture conditions, the ability of the axillary meristem to produce tendrils is closely correlated with the ability of the apical meristem from which it originated. The interest of these results is discussed from a fundamental standpoint. It allows to suggest an improved process of adult vitroplants production under high carbon dioxide level in which the relative importance of the selection of microcuttings and the number of subcultures is defined.Key words: maturation, micropropagation, tendrils, Vitis vinifera.
