The objective of this research was to evaluate the influence of Chandala (Aloe vera L.) on the germination of soybean seeds (Glycine max L.). The same took place from January to September 2022, in the Biology laboratory of the Instituto Superior Politécnico do Cuanza Sul, Angola. Aloe vera leaves were collected, washed in distilled water, dried and their mass determined. Aloe vera leaves were collected, washed in distilled water, dried and their mass determined. The 50% hydroethanolic extract was produced. The experiment was carried out in different doses of extract, constituting the treatments. The germination experiment was carried out in Petri dishes, in a completely Randomized Block Design, with four treatments and 15 replications (15 Petri dishes). The treatments were: Control (T0); 50% (T1); 75% (T2) and 100% (T3). The germination percentage (%G) and the germination speed index (IVG) were evaluated. Evaluations were performed between the fourth and fifteenth day, with an interval of two days. The data were analyzed using the SAS program (Statistical Analysis Systems). The concentration of 100% caused a negative effect and 75% was the most efficient on the indexes evaluated. It is concluded that higher doses of Aloe vera extracts cause destruction of the energy reserves of the seeds and, consequently, death on the seedlings.
