Abstract:

In order to explore the influence of meteorological conditions on the comprehensive quality of sweet cherry in Guanzhong area of Shaanxi Province, this paper took ‘Brooks sweet cherry’ as the research object, adopted the method of fuzzy comprehensive evaluation, and established the comprehensive indexes of internal and external quality of cherries in different areas. To further analyze the impact of different weather conditions on the quality of cherries, this paper used data from four meteorological stations in Baqiao, Liquan, Yaozhou, and Dagu in 2024 and employed correlation analysis and other methods to analyze the weather conditions that affect various quality factors of cherries. The results showed that the external quality of cherries from Liquan region was the best, and the internal quality of cherries from Baqiao region was the best. The appearance quality of cherry fruit in four regions was less affected by regional meteorological factors, indicating that the appearance of cherry fruit had strong adaptability to ecological environment. The difference of soluble sugar (TSC) was not obvious, indicating that the soluble sugar of sweet cherry could maintain a stable level in Guanzhong area. The sucrose content varied significantly in different regions, indicating that sucrose was easily affected by regional meteorological conditions. The content of Vc in the cherries from Baqiao was significantly higher than that in other areas, indicating that the meteorological conditions of Baqiao were more conducive to the accumulation of Vc. The correlation analysis showed that the external quality of cherry was positively correlated with the average temperature difference during the whole growth period, and was significantly correlated with the average temperature and the maximum temperature. The internal quality of cherry was significantly correlated with precipitation and minimum temperature. The results of this study can provide a scientific basis for the sustainability and industrial development of the sweet cherry industry in the Guanzhong region.

Key words: sweet cherries, external quality, internal quality, comprehensive fuzzy evaluation, correlation analysis
