Abstract
In this study, the germination responses of Petunia hybrida seeds to light were investigated, and the following results were obtained.<br> 1) The increase of germinative capacity of petu-nia seeds during the dry storage at room tem-perature was accompanied by the increased light-sensitivity. High sensitivity was gained 6 months after the harvesting.<br> 2) The light-sensitivity of petunia seeds increased with the lengthening of presoaking, up to 48 hours, before the illumination. Moreover, as short as 5 minutes' illumination brought high germination, when it was given 20 hours after the imbibition.<br> 3) Red light was more effective than green or blue light in increasing the germination percentage.<br> 4) Petunia seeds were similar to lettuce seeds in the photoreversibility of their response to red and infra-red radiation.<br> 5) The promoting effect of gibberellin was very remarkable, though nitrates and thiourea could not increase the germination.
