ABSTRACT
Background Hypericum perforatum is used as a medicinal plant, mostly in antidepressant treatment. With endogenous and exogenous dormancy, more studies about the germination of the seeds are necessary.

Aim:

To evaluate the effect of temperature and of preparations of high dilutions on the germination of seeds of Hypericum perforatum. Methods Three bioassays were carried out in chambers of germination, using a completely randomized experimental design and in duplicate. In the first bioassay, of temperatures of 20, 25 and 30 ºC was evaluated, with 20 replicates and 50 seeds in each replicate. In the second, the effect of high dilutions (Kali carbonicum, Natrum muriaticum, Phosphorus and Silicea terra in 12cH) using 4 replicates with 50 seeds each. In the third, Kali carbonicum was tested at 6, 12, 20, 30 cH with 50 seeds and 4 replicates. The percentage of germination, germination rate index (GRI), average germination time (AGT) and seedlings with cotyledons. The data were analyzed through the R software at a 5% significance. Results At the temperature of 25 °C, 63% of the seeds germinated while at the temperatures of 20 and 30 °C the percentage was 26% and 18%, respectively. In seeds treated with Kali carbonicum 12cH the germination rate increased significantly in relation to the control group. Kali carbonicum 6cH increased the GRI of the seeds, while at 20cH, it increased the AGT, showing delay in germination. Conclusion The use of the Kali carbonicum assists in the breakage of dormancy and average time of germination in Hypericum perforatum seeds. (AU)
