Abstract
The Crocus sativus, an endangered medicinal and aromatic plant in Morocco, has a low propagation rate in natural conditions and, therefore, an efficient method for in vitro propagation is required. This study investigated the effects of various hormones on the induction of callogenesis and callogenesis in C. sativus corms using the Box-Behnken experimental design. The best shoot formation was obtained with Murashige and Skoog fortified with 3 mg/L 6-Benzylaminopurine. On the other hand, callus formation was obtained with 3 mg/L 1-Naphthaleneacetic Acid or 3 mg/L 2,4-Dichlorophenoxyacetic Acid. However, a combination of 3 mg/L 6-Benzylaminopurine, 1.056 mg/L Indole Butyric Acid, and 3 mg/L 2,4-Dichlorophenoxyacetic Acid allows 50% caulogenesis and 60% callogenesis. The in vitro regeneration system could be utilized for both conservation and largescale multiplication of Crocus sativus corms.
