Sustratos y dosis de fertirrigación en la acumulación de azúcares totales y el crecimiento de Agave salmiana (asparagaceae)

Abstract

leaf rosette S100-R7. plants of S100-R3, total the dry than in the mixture of volcanic rock and agave stalk. The total biomass dry weight and the aerial part were significantly higher in the plants grown in perlite and volcanic rock. The concentration of total sugars and glucose was higher in the plants that grew in pearlite and the mixture of volcanic rock and stalk, while the fructose and sucrose were lower in the plants grown in pearlite and the mixture of volcanic rock and stalk. The perlite substrate was more efficient and irrigated every third day with 25% of the concentration of the Steiner Solution in the plant growth of Agave salmiana . Those plants showed greater total dry weight, and number of leaves spread. The effect of the inert perlite and volcanic rock substrates on the variables total biomass dry weight and the part area, length and width of the plant leaves was significantly higher than in the mixture of the inorganic and organic substrates.
