Gibberellic acid and seed dormancy breaking in Impatiens parviflora, I. glandulifera and I. balfourii

Bulletin de la Societe Royale de Botanique de Belgique 110(1/2): 113-118

Gibberellic acid and seed dormancy breaking in Impatiens parviflora, I. glandulifera and I. balfourii

In studies on 3 Impatiens spp., seeds of I. balfourii were stored at 25 deg C either dry or in moist air for 10, 12 or 14 weeks. Batches were then transferred to 5 deg. Dry seeds were held at this temperature for 0, 2, 4, or 6 days and moist-stored seeds for 0, 1, 2, 3, 4, 5, 6 or 7 weeks. Gibberellic acid at 100 or 500 p.p.m. was then applied to the seeds for 24 h, before they were transferred to 25 deg for 10 days to encourage germination.
