THE INFLUENCE OF LIGHT ON <i>DACTYLORHIZA INCARNATA</i> (L.) SOÓ (ORCHIDACEAE) SEEDLINGS GROWTH AND DEVELOPMENT <i>IN VITRO </i>
Dactylorhiza incarnata seedlings in culture in vitro under the light grow smaller and with a higher number of absorbing hairs compared to seedlings in the dark. In different lighting conditions, they go through the same stages of development, but the timing of their occurrence differs. The lighting of crops in two months after the start of cultivation can be used to accelerate the development of seedlings.
