A trellis system called the crawled cordon training involving
covering wild crop (Li et al., 2010), which has the minimal pruning
for lowering the cost of winegrape production and controlling
moisture migration of the vines, was developed to aid mechanization
operation of canopy management, fruit harvest, dormant
pruning and overlaying soil in winter by the experimental studies.
Although this system has been applied successfully in commercial
grapevines more than 20 years ago, there have been few formal
reports of experimental evaluation to sustain this trellis system, let
alone its effects on the aroma ofthe wine made from its berries. Previous
work focused mainly on effects of trellis on general indices of
berry without controlling shoot and bunch counts per vine (Wolf
et al., 2003). Hence, it is necessary that the traditional ILSP (Fig. 1)
was taken as control to compare the effect of CCT (Fig. 2) on aroma
quality under controlling shoot and bunch counts per vine among
the treatments first.
