Résumé:
Watermelon is a cucurbit originating from the African continent, it is a herbaceous plant
with an annual vegetative cycle. This crop can be propagated through direct sowing in
the soil or through seedlings produced in containers, which are transplanted to the final
location. Thus, this work aimed to evaluate the influence of different substrates on the
Germination Speed Index and evaluate the initial growth of Citrullus lanatus on different
substrates. The experiment was conducted in plastic multicell trays in the greenhouse of
the Education and Health Center at the Federal University of Campina Grande. The
variables analyzed were Germination Speed Index, Germination Percentage, Number of
Definitive Leaves, Aerial Part Length, Root Length, Stem Diameter, Green Aerial
Fitomass, Green Root Fitomass, Dry Aerial Fitomass, Dry Root Fitomass, Quality Index
by Dickson. The experimental design used was randomized blocks in a 4 x 2 factorial
scheme, with eight treatments, three replications, 96 cells from the four blocks used, 96
watermelon seeds (48 seeds of the Colt variety and 48 seeds of the Magnum variety). The
data obtained were analyzed using the Tukey test at 5% probability in the Sisvar computer
program. It was observed that there was no interaction between the substrates and the
seeds of the varieties used.
