Recently, some characteristics of the J. curcas seed structure have
been described. The cells of the testa are walled and unlignified, and
the outer epidermis is made of narrow columnar cells with slightly thickened and pitted radial walls and dark brown content (Fig. 5c). The inner epidermis generally is formed with short, thin-walled, columnar cells (Khasim et al., 2013). These observations are consistent with the
observations made in this study (Fig. 5c); 40 DPA the testa of the
seeds is dark brown, suggesting that the seeds have reached their total
maturity as it has been also reported by Rao et al. (2008). By contrast,
in R. communis , also a member of the Euphorbiaceae family , the fruits
reach their maturity 60 DPA
