The purpose of this work was to evaluate the yield and quality of Merlot and Cabernet Franc grapes cultivated in Te Kauwhata two tier (TK2T) conduction system in greenhouse. Productive parameters: leaf surface, mass and number of bunch, yield per plant andberries per bunch. Qualitative parameters: Brixº, probable alcohol, total acidity and polyphenol index. Merlot and Cabernet Franc varieties with different trunk heights had significant effects on leaf surface, mass and number of bunches and yield per plant. Qualitative parameters were not influenced. TK2T has high yield for both varieties, highlighting the trunk height of 1.5 m, with better response to Merlot.
