Influence of substrates in the production of Pinus maestrensis Bisse plants in black polyethylene bags in the municipality of Buey Arriba in the province of Granma (Original)

Abstract

The months of December of 2011 to March of the 2012. Seeds of Pinus Maestrensis Bisse utilized in the program of reforestation of the county were utilized. For the sake of characterizing the quality of the plant Pinus Maestrensis Bisse on a randomized design's base, they set up three treatments: T 1 (I Sole 100 %), T 2 (earthworm’s Humus 30 % + I Sole 70 %), and T 3 (Organic Matter 30 % + I Sole 70 %). The variables of evaluated growth were: height of the plant, diameter of the neck of the root, fresh weight of the radical part, fresh weight of the shaft of the plant, fresh weight of the air part of the plant, dry weight of the radical part, dry weight of the shaft and dry weight of the air part of the plant. For the mensurations they took 15 plants for treatments, at random, the data were processed by means of an analysis of variance of simple classification and the stockings were compared by multiple range from Duncan to 5% of probability. It was gotten the sophisticated like better sustract with the help of (humus of worm and floor), where they were reached the you improve security of the attributes and evaluated indexes.
