| Abstract | ||
| The present study describes plant regeneration via somatic embryogenesis from cotyledonary node callus. Callus cultures were derived from cotyledon node segment excised from Trigonella foenum-graecum L. axenic seedlings grown in agar solidified Murashing and Skoog's(MS) medium supplemented with Benzyl adenine BA at 2.0 mg l-1 and Naphthalene acetic acid NAA at 1.0 mg l-1. These cultures were stimulated to form somatic embryoids at 32% frequency of in agar-solidified MS medium containing NAA at 0.5mg l-1 in the presence of 15% v/v coconut water. Light microscopy examination of sections of heart embryos stage proved the presence of vascular system. Transfer of other developmental stages of embryos to the same induction medium led to the development of secondary somatic embryos and embryoids into plantlets in agar-solidified MS medium lacking hormones. They were readily rooted in MSO and successfully transferred to soil. | ||
