Abstract

Hellebores (Helleborus spp.) are winter-­‐flowering ornamental plants that are difficult to propagate in tissue culture. To improve the performance of hellebores during micropropagation, preliminary tests were done to standardize temperature and light quality. The effects of growth hormone type and concentration on plant multiplication were also assessed. Performance remained low, and plantlets often displayed visible contamination.
