Tamanho de amostra para teste de germinação de Senegalia bahiensis (Benth.) Seigler & Ebinger

Abstract

In seeking to meet the targeted studies will lack standardization of germination of native species tests, this paper aims to define the number of seeds per repetition and the number of repetitions for testing germination of the species Senegalia bahiensis. The experiment was mounted in a completely randomized design in a factorial 5 x 9, five numbers of seeds per replicate (20, 25, 50, 75 and 100) and nine numbers of repetitions (3, 4, 5, 6, 7; 8, 9, 10 and 16), with five replicates per treatment. The germination test was conducted in germitest paper with germinator, BOD at 30 ° C and continuous light. Counts were performed on the second day and the seventh day after the assembly of the experiment, and was rated the coefficient of variation for germination percentage, speed of germination, dry weight and length of shoot and root. The authors verified that the number of factors and seed reps act independently in response variables having an influence only on the number of seeds and the number of repetitions a non significant factor. However, for germination to Senegalia bahiensis tests, considering all variables, are recommended three replicates 56-67 seeds totaling 168-201 seeds.
