Abstract
The investigation was executed in the Experimental Agriculture-forest Station of Jibacoa, county of Villa Clara, Cuba, with the objective of evaluating the effect of several substratum types on the development of vitroplants of Coffea arabica L. in the phase acclimatization. Hybrid F1-436 was used. Seven resulting treatments of the combination of organic matter, soil, sand and zeolite were proven. The height of the plant, the diameter of the shaft, dry weight of the aerial part and the roots were evaluated. An experimental totally randomized design was used. A variance analysis and comparison of stockings according to the test of Duncan for (p < 0.05), with the statistical program Infostat version 1.0 was carried out. The treatments where combined 50 % of organic matter + 25 zeolite % + 25 % of sand and 25 % organic matter + 25 zeolite % + 25 % of soil +25 % of sand was those of better development in all the evaluated variables. The vitroplants acclimatized in substratum that didn’t have in their composition included the zeolite showed smaller growth and development.
