Bio-organic Alternatives for Propagation of Psidium Guajava (L.) through Stem Cuttings
Article Sidebar
Main Article Content
Resumen
The aim of this study was to use different stimulators for guajabo propagation using stem cuttings in semi-controlled conditions, on "La Nueva Esperanza" farm, run by "Renato Guitart" Strengthened Cooperative of Credits and Services, in the municipality of Camaguey, Cuba, between February and May, 2016. A chamber with zeolite substrate (1 - 3 mm diameter) was used for propagation, whereas irrigation was scheduled and localized. A completely randomized design was used for evaluation, with 6 treatments and 3 replicas. The number of plants with buds, plants with roots, leaves, and live plants achieved, were evaluated. Simple variance analysis (SSPS version 11.5.) was performed, and the means were compared according to the Duncan´s test (p:0.05). The bio-organic alternatives applied were efficient in stimulating the physiological mechanisms for plantlet growth. The best phenological behavior was observed in treatments with the natural liquid humus plus indoleacetic acid, the natural liquid humus plus phosphoric acid, and the fortified liquid humus.
