Abstract

PEDROZA-SANDOVAL, Aurelio et al. Morphometric characteristics and quality of aloe vera gel (Aloe barbadensis M.) applying algae extract (algaenzims) and compost. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.1, pp.7-18. ISSN 2007-0934.

The study was conducted in 2011-2012 and aimed to evaluate the effect of different sources and doses of fertilizers on leaf growth and quality on aloe vera gel, the latter as a product of high demand in the market. A random split plot block design with three replications was used. The main plots were algae extract (algaenzims) doses (0, 7 and 14 L ha^-1) and subplots compost doses (0.5 and 10 t ha^-1). The measured variables were: plant height, width, length and thickness of leaf; while in juice and gel, pH, °Brix, total solids, settleable solids in methanol, proteins, carbohydrates, gel content and macro (P, K, Ca, Mg and Na) were measured. Plant height and leaf length were significantly higher (p≤ 0.05) by applying 14 L ha^-1 of algaenzims. Gel content, sugar and settleable solids in methanol were significantly higher, 273 days after the first application of the biofertilizer (DDPAB) (December), 273-393 DDPAB (December-April) and 273 DDPAB (December), respectively. The content of P and Mg were significantly reduced, 273 DDPAB (December) by applying 10 t ha^-1 of compost, then the content of these elements is recovered. The carbohydrate and protein content increased significantly at 273 DDPAB (December), which is critical to identify the cutoff date of aloe leaf.
