Mildura Victoria, Australia: ATGAc2014  ap. 84.  aTropical and subtropical viticulture can be detined in tive types according the Multicriteria Climatic Classitication (Tonnieto and Carbonneau, 2004): tropical dry, tropical wet, tropical alternatively dry/wet, sub-tropical alternatively dry/wet and sub-tropical dominantly wet. They include a wide range of countries and very particular tropical viticultures in Brazil, Peru,Venezuela, Colômbia, Guatemala, India, Thailand, and others characterised as subtropical in the South of Brazil, Uru guay, Korea,Japan and others. The vine adapts differentially in every climatic condition by imposing a particular management system, resulting in varied yield and quality of grapes. Thus, the focus here is going to be in the dry tropical viticulture, highlighting growing regions like Piura in northern Peru (05° 12'00 "S 80° 38'00"W), Zulia in Venezuela (10° 57 '51 "N, 71° 44 '8" W) and Petrolina and Juazeiro, in the Northeast of Brazil (9° 23' 39 "S,40 ° 30 '35"W). Viticulture in these regions are the nearest of the Equador line in the world and have higher similarities between them. São Francisco Valley can be considered as an example for this group as one of the pioneers and most technically advanced for growing table grapes. The climate presents an average annual precipitation of 505mm, annual average relative humidity of 60.7%, annual average temperature, maximum, and minimum, respectively 26.rC, 32.0°C.and 20.8°(, The main common aspects in viticulture under tropical climate are that vine grows continuously, there is no rest period in winter and can be made up to three crops at any time of year. As the buds do not come into physiological dormancy, they are apt to sprout at any time of year that pruning is performed. This is the main comparative advantage in tropical viticulture, the grower can decide what is the most convenient time of year for pruning and harvesting grapes as a function to achieve better prices in the market.  aGrapes  aUva  aViticultura  aVitis Vinifera  aCultivo  aUva de mesa
