Question

Banana plantlets produced through tissue culture are raised under highly controlled laboratory conditions. Why must these plantlets undergo hardening in a nursery before being transplanted into open-field conditions?

Tissue-culture-derived banana plantlets, having been raised under artificially controlled, sheltered laboratory conditions with high humidity and filtered light, initially lack the physiological toughness such as a well-developed waxy leaf cuticle needed to survive direct exposure to harsher outdoor field conditions, making a gradual hardening process in a shade-net or polyhouse nursery an essential intermediate step before final field transplanting.
