However, plantlets produced from in vitro cultures have to switch from heterotrophy to autotrophy and possess abnormal anatomical and physiological characteristics, such as under developed leaf cuticle and lower stomatal density, which necessitates acclimatization in order for them to cope with edaphoclimatic conditions (BARBOZA et al., 2006).
