This Work was carried out on period of February to July of year 1999, in order to evaluate the effects of three salinity sources from water irrigation (dam water, water rich in sodium chloride and rich in magnesium chloride) to electric conductivity levels 0.5;1.0;2.0;3.0;6.0 and 9.0 dSm-1, on initial growth of soursup plants Annona muricata L, cultivate Morada. During the first fifty days in any one salinity sources studied data of leaves area and dry matter production of leaves plants increased with increment of water salinity level of 0.5 to 2.0 and till 3.0 dSm-1. In same period the substratum salinity index was expressively increased and soursup plants presented it as moderately tolerant to soil salinity during it initial growth. In spite of water rich in magnesium chloride to be the saline source that least contributed to increase of substratum salinity level was the salt source that more induced reduction of studied variables in relation the dam water and water rich in sodium chloride this showed that soursup was more sensible to magnesium chloride that dam water and the water rich in sodium chloride.
