Their stem explants were grown in MS or modified MS basal medium. The effects of plant hormones on organogenesis and transplanting of test-tube plantlets were studied.

By placing sterilized cuttings in test tubes with salts, vitamins, plant hormones, and seaweed gel, they got the plants to sprout and then raised them in soil in greenhouses.

Test tube bulb of mask lily ROCCO was used to investigate the influence of low temperature, plant hormone, sugar and illumination intensity on the proliferation of the bulb.
