Effect of substrate composition on rooting of cuttings of <i>Hyptis suaveolens</i> (L.) Poit

Abstract

Hyptis suaveolens (L.) Poit., is considered to be a plant of high therapeutic potential. The objective of this study was to evaluate the effect of the different composition of substrates for rooting medians of Hyptis suaveolens. The study was conducted in greenhouse Sector Soil Environmental Sciences Department, Federal Rural University of the Semi-Arid (UFERSA) in May 2010. The treatments were the following substrates: arisco soil (T1), sand (T2), mixture of manure and sand (2:1) (T3), a mixture of sand, arisco soil and manure (1:1:1) (T4), and mixture of arisco soil, sand and humus (1:1:1) (T5). The experimental design was a completely randomized design with five treatments and four replications and 10 cuttings per plot. The evaluated characteristics were the rooting percentage, longest root length, diameter of the cuttings, dry mass of shoot and root. Substrates sand, arisco soil, and the combination of their mixture with cattle manure, stood out from other substrates in the percentage of rooting. Therefore, a combination of mixed sand, arisco soli and cattle manure is recommended for the production of seedlings of bamburral.
