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

, : 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

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.

GA cannot be considered as a chilling [stratification] substitute in dormancy breaking of I. parviflora, I. glandulifera and I. balfourii seeds; rather it works in speeding up the germination processes.

This increased RNA synthesis is accounted for by an increase in DNA template available for transcription and (subsequently) increased RNA polymerase activity. It is suggested that g.a. breaks dormancy by a mechanism of gene de-repression, as indic...
