Abstract

Phaseolus vulgaris L. seedlings were grown under different air humidities simulating conditions during micropropagation (very high humidity during in vitro cultivation and low air humidity after transferex vitro).

The functional stomatal apparatus developed after a short period of growth at low air humidity at the beginning of plant ontogeny or after transfer from high to low air humidity, but not in plants grown steadily under high air humidity.

The ability of stomata to regulate gas exchange was not persistent and disappeared after transfer of plants from low to high humidity.
