Roots or top-growth on tropical lily tuber?

[keyworth63]

I overwintered tubers from my tropical lilies by coating them in an anti-fungal paste then storing them in damp sphagnum moss in the dark in ziplok bags at about 55 degrees. Upon recent inspection (early April), many of them show new growth, but I don't know if this is root material or top growth, and this affects how I should plant them. Please see the attached photo, and I would appreciate the opinion of any experts out there to identify the nature of the sprouting.

Per this youtube, it shows the pointed end being the growing tip. With no roots , yet

"SPRING: Late March through early April, plant the tubers in a small pot or tray full of sand with the top of the tuber showing. Be sure to wash off any fungicide you may have used in the fall. Place the pot in warm (65-75o) water with 3" of water above the crown. Place them under a grow light or in a sunny window. The tubers should sprout in a few days. As they grow, repot the plants in larger containers and fertilize them. Then drop them into your pond late May/early June. Be careful- if the water temperature of your pond is lower than the water you used for sprouting, the lilies may go dormant and lose several weeks of growing time."

I used to keep them in my indoor planted tank. I got the bulbs out of those packs that can be bought at petco.
