Bulliform cell area can be used as indicator of adaptability to cultivation in environments with water deficits (or high environmental temperatures) because these cells are involved in leaf curling that diminishes the leaf surface area (and thus water loss through transpiration)--and the larger the area occupied by bulliform cells, the better the response of the genotype to dry/hot environmental conditions.

These bulliform cells lose water rapidly during periods of stress and cause the leaf to curve upward, eventually rolling up as the wilting process progresses and thus helps the plant to conserve water.

In periods of water stress, the bulliform cells lose their stored water, causing the grass leaf to roll up edge-to-edge, limiting further water loss from the upper epidermis.
