“…More recently, plumular tissues from germinating zygotic embryos [11,[36][37][38] and rachilla sections from immature inflorescences [39,40] have been successfully used for coconut SE. Of these, the plumular tissue was found to be the most suitable for SE [30,[41][42][43].…”

“…According to Montero-Córtes et al, 2010 [74], GA 3 (0.5 µM) improved the formation and germination of coconut somatic embryos, with the maturation rate increasing 1.5-fold, and the number of somatic embryos formed per callus clump increasing 2.0-fold. Gibberellic acid has also been included in a recent protocol developed for the germination of coconut somatic embryos derived from plumular [38] and inflorescence tissues [39] at concentrations of 2.8 and 4.6 µM, respectively.…”

Coconut [Cocos nucifera L.] is often called “the tree of life” because of its many uses in the food, beverage, medicinal, and cosmetic industries. Currently, more than 50% of the palms grown throughout the world are senile and need to be replanted immediately to ensure production levels meet the present and increasing demand for coconut products. Mass replanting will not be possible using traditional propagation methods from seed. Recent studies have indicated that in vitro cloning via somatic embryogenesis is the most promising alternative for the large-scale production of new coconut palms. This paper provides a review on the status and prospects for the application of somatic embryogenesis to mass clonal propagation of coconut.

“…Most of the early progress was made using rachis explants obtained from inflorescence ( [15,16]. So far, the rates of embryogenic callus formation, somatic embryos and their germination remained very low [17]. In the mid-1990s, the Scientific Research Centre of Yucatan (CICY, Mexico), in collaboration with Wye College, tried to test different parts of the zygotic embryos, including the plumula, which was most sensitive to the formation of embryogenic callus, somatic embryos and subsequent conversion to seedlings with low yield [18].…”

The coconut tree (Cocos nucifera L.) is a fruit plant that contributes significantly to improved nutrition, food security, job creation, and household income in Benin. However, its production is suffering from the unavailability of certified seedlings. The present work aimed to optimize the propagation of coconut trees through the somatic embryogenesis technique. Zygotic embryos were cultured in vitro on Y3 medium supplemented with 0.7% Agar; 2.5 g/l activated charcoal, 5% sucrose to obtain haustorium, and the radicle explants for somatic embryogenesis. Three months after, callus and somatic embryos were induced from haustorium and radicle on medium Y3 supplemented with different doses of 2,4-D (0.3 and 0.35 mM) and coconut water (0, 50, 100 and 150 ml/l). 80% of callus was induced of induced with haustorium explant on Y3 medium supplemented with 0.7 mM 2,4-D. The combination of 2,4-D and coconut water resulted in the highest average number of somatic embryos with 59 and 63 embryos obtained respectively on Y3 medium enriched with 150 ml/l coconut water and supplemented with 0.3 mM and 0.35 mM 2,4-D. Using haustorium explant for mass propagation through somatic embryogenesis remains an exploring way for in vitro seedling of coconuts.
