Abstract

Cultivation, regeneration and conservation of wild plant species are, generally, challenging, mostly due to their SEED DORMANCY and specific germination requirements.Jimsonweed (Datura stramonium L.) an important medicinal plant which is also extensively used in plant virology research has a considerable seed germination problem. This study was conducted to develop a simple seed germination protocol for JIMSONWEED. A factorial experiment arranged as completely randomized design (CRD) with three replications, assessing effects of seed SCARIFICATION, gibberellin and potassium nitrate (at concentrations of 0, 100, 500, 1000 and 2000 ppm). Five days after treatment, percentage of seed germination, radicle and plumule length were measured, revealing the key role of mechanical seed SCARIFICATION treatment as a prerequisite for germination of JIMSONWEED seeds. The germination rate as well as radicle and plumule length of scarified seeds were drastically influenced by concentrations of GIBBERLLIN and potassium nitrate. No germination was observed in scarified seeds in the absence of GIBBERLLIN and potassium nitrate in water. Maximum percentage of seed germination (63%) was obtained when a chemical treatment of 100ppm GIBBERLLIN and 500 ppm potassium nitrate used together on scarified seeds.
