Quiroz-Figueroa et al. (2001) have also reported that picomolar concentrations of SA applied to the culture medium increase cell growth and somatic embryogenesis in tissue cultures of Coffea arabica. Regarding the effect of SA on the flowering processes, Oota and Cleland (1975) and Cleland and Ben-Tal (1982) showed that the application of SA in the growth medium of Lemna gibba could substitute photoperiod effect on flowering promotion. Endogenous SA levels however, have not yet been proven to be responsible for the flowering effect, although it is known that flowering is affected by photoperiod and stress factors (Shimakawa et al., 2012).
