Abstract: The relationship between meteorological factors and Ralls apple (Mulus pumila, Mill) quality was statistically analysed with data of 16 successive years. The result showed that fruit soluble solids, titratable acid, firmness, and Brix/acid ratio were closely related to various meteorological factors in different growing stages, and the correlation coeffecient was0.8769* *, 0.7671* *, 0.8929* * and0.8950* *, respectively. The result was confirmed with the path analysis and multi-regression analysis. This study showed that the main direct factors affecting soluble solids, titratable acid, firmness, and Brix/acid ratio were the sunshine time between late July and middle Sep. , the precipitation between July and Aug. , the average temperature between late June and early July, and the average temperature in middle to late July, respectively.

Key words: Meteorological factor, Ralls apple, Quality
