Effects of Mechanical Pruning on the Yield and Quality of Muscadine Grapes

摘要: Dixie muscadine grapes ( Vitis rotundifolia Michx.) were mechanically pruned and then either adjusted to 800 or 400 nodes per vine not hand following trimming for three consecutive years. Vines trained a quadrilateral cordon system mechanical pruning cuts made 15 20 cm from the cordon. Mechanical with no touch-up resulted in much higher yields during first second year, but third. had lowest yield all Increasing severity increased berry weight generally soluble solids pH. Wine produced vines weaker aroma intensity lighter color wines this treatment subsequent years similiar character other treatments.
