(2015) worked with the adaptation of apical meristem multiplication protocols (Figure 3) in 'Smyrna' (Zither and Soltani) and 'San Pedro' fig cultivars (Bither and Adiadh) and with rare and recalcitrant pollinating cultivars such as Assafri, for the purpose of seedling sanitation, indicating that in apical buds with 0.5 mm in length, multiplication is favored mainly using the MS medium added of 0.5 mg [L.sup.-1] BAP + 0.1 mg [L.sup.-1] naphthalene acetic acid (NAA) and 0.1 mg [L.sup.-1] GA3.
In the apical meristem, ablation of the selected cells can increase the persistence of meri-clone regeneration, which results in the production of virus-free plantlets at high propotion (Nascimento et al., 2003; Wasswa et al., 2010; Wang and Valkonen, 2008).
