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.
In CCT, all vines planted were pruned to one cane along the surface
of soil and five shoots per cane. Every shoot with a space of
approximately 15–20 cm was trained to the vertical trellis during
the growth period and a two-node spur in the late October (Fig. 1).
While in ILSP, there was an acclivitous stem extending to the first
wire positioned at 50 cm from the ground and continued to elongate
horizontally and kept the five shoots trained to the “V” type
trellis above the first wire in the growth period (Fig. 2). The other
followed CCT
