Each training system affecting the volatile concentration of wine is closely related to the specific growing
conditions of grape. The aim of this work is to evaluate the influence of different training systems, such
as crawled cordon training (CCT) and independent long-stem pruning (ILSP), on the volatile composition
of Ecolly wine in Weibei Plateau region in three periods (July 31, August 10 and 24). Total aroma concentration
(271.15 mg L−1) and ethyl octanoate concentration (84.60 mg L−1) were the highest for ILSP in
August 24 in aroma compounds. However, total aroma concentration of CCT exceeded the ILSP in July 31
and August 10, respectively. ILSP could lead to higher acetate esters compared with CCT exceptfor August
10. Ethanol esters were also strongly influenced by training systems in July 31 (CCT > ILSP) and August
24 (ILSP > CCT), except for slight influence in August 10. But other esters were not strongly impacted by
training system. Despite the highest higher alcohols in ILSP in August 24, CCT still displayed significant
higher concentration in the first two harvesting times than ILSP. Organic acids showed the same trend
as higher alcohols in the experiment. Odor activity values (OAVs) of the 16 aromas compounds showed
similar results. Results have shown that CCT improved the accumulation of aroma compounds in early
wine, if harvesting time need to be postponed, ILSP was also a suitable select. Whereas, a strongly suggestion
of CCT was made because stabilization of yield and quality could be guaranteed by CCT annually.
