Produção de mudas de Senegalia bahiensis (Benth.) em três diferentes volumes de tubetes

Abstract

Senegalia bahiensis (Benth). Seigler & Ebinger popularly known as hawthorn, stick-to-zone and white jurema is a tree species’ in the savanna biome. This study aimed to evaluate the quality of Senegalia bahiensis seedlings grown in differents volumes of tubes. The experiment was conducted at the experimental nursery production of seedlings Forestry, Federal University of Recôncavo of Bahia, located in Cruz das Almas campus. The fruits were collected in 12 Senegalia bahiensis matrices being manually processed and then their seeds were sown in three volumes of tubes (55, 180, and 280 cc). The experiment was conducted in a completely randomized design with four replications with 49 seedlings per replicate. The variable diameter (cc), height (cc), leaf number (NF), dry mass of the root system (MSSR) and (MSPA), average daily increment in diameter (IMDD) and height (IMDA) were evaluated. The seedlings grown in tubes of 180 and 280 cc showed greater expansion with respect to all variables except the MSPA, MSSR and NF in which the cartridge 280 cc had the best average. The seedlings produced in lower volume (55 cc) container had the lowest averages for all variables. For the production of seedlings of S. bahiensis, we recommend the use of cartridge 180 cm3 due to the production cycle is less when compared to the other two cartridge volumes (55 and 280 cc), still favoring the possibility of reducing costs by producing seedlings of equal quality when compared to seedlings grown in tubes of 280 cc.
