Improved germination of threatened medicinal Prunus africana for better domestication: effects of temperature, growth regulators and salts

摘要: Prunus africana is an endangered medicinal species and has been classified as a priority for domestication in Cameroon. However, the seeds rapidly lose their viability during storage at room temperature after 2–3 months. This study aimed to improve seed germination of P. by germinating different temperatures (4 °C, 28 °C) using concentrations growth stimulators (sodium nitrate gibberellic acid) salts. had 91.7% 4 °C 1 month storage. Growth regulators considerably influenced 6 months reached 66.0% with 10 mM acid 100% sodium nitrate. Approximately three shoots per were developed, indication polyembryony. Histochemical analyses revealed presence protein-like bodies close embryo axis accumulations starch 7 days germination. After 14 days, amyloplasts dark protein various sizes observed. The outcome this will contribute better conservation.
