The pretreatment of seeds of 6 sudanese acacias to improve their germination response

, : The pretreatment of seeds of 6 sudanese acacias to improve their germination response. Seed Science & Technology 13(1): 111-120

Four experiments using seed of Acacia tortilis ssp. spirocarpa, A. ehrenbergiana, A. nubica, A. nilotica ssp. nilotica, A. albida and A. seyal var. seyal were performed. The first tested the assumption that seed coats of the 6 acacias are impermeable to water and the other 3 investigated the effects of mechanical, chemical, or biological seed coat treatments on germination response. The results obtained showed that over all experiments, a small percentage of intact seed of the 6 spp. imbibed water without pretreatment of the seed coat. Thus, the above assumption is not tenable as a general statement about all acacias. None of the methods used succeeded in breaking the seed dormancy of all the hard seed. Mechanically scarified seed soaked in tap water for 8 min gave the best overall germination response.
