Uso de enraizadores naturais caseiros na produção de mudas de Hibiscus spp

Abstract

Rooting and germinating hormones exist in various types of plants. The so-called synthetic hormones are of various types and often difficult to acquire either by supply or price, which makes many seedling producers look for more affordable and low cost alternatives originating the so-called home natural roots. Except for Cyperus spp and other plants not always present in the Brazilian flora, research references do not validate many of these so-called roots even in many cases proving to be effective. In order to validate some of these formulations a research was conducted with Hibiscus spp, it is a plant much coveted by collectors. The experiment was carried out at the Agrarian Sciences Center, Campus II, in Areia, Paraíba, Agroecology Module from August to October 2019. The preparation of the extracts was performed according to the most appropriate and reference methodology resulting in the treatments: T1- Cinnamon powder concentrated; T2 - Cinnamon powder 50%; T3- Concentrated coffee powder; T4- Coffee powder 50%; T5 - Concentrated alcohol vinegar; T6- 50% alcohol vinegar, T7- Refined sugar powder concentrate; T8- Sugar 50%; T9- Concentrated Bean Macerate and T10- Bean Macerate 50%). The cuttings used were classified in Apicals; Median; Basals. After immersion in the extracts, the cuttings were placed in black polyethylene bags containing washed river sand. After a period of 45 days, the following variables were observed: survival, shoots, callus and roots. The results showed that home rooting actually promoted effects on the observed variables and may be recommended Concentrated alcohol vinegar, refined concentrated sugar powder; Refined sugar powder 50%, Macerado concentrated bean and Cinnamon powder 50%. Apical cuttings are the most suitable for the production of hibiscus seedlings and, in a scale production, it is necessary to verify which interaction yields the best cost benefit. Longer experimentation with inclusion of control treatments is recommended for better validation of known roots in the empirical domain.
