Yes. There are. Certain plants are very sensitive to initial changes such as eriocaulon and sygonanthus are rather sensitive plants. Otherwise you're pretty safe planting whatever whenever.

Some plants will melt if exposed to high levels of ammonia. Not sure on what plants will melt since I haven't cycled a tank in a while but I know floaters and fast growing stems will help reduce the ammonia in the water during a cycle.

If you are doing the fishless cycle that calls for adding ammonia to 3 ppm, there are plants that are not good for this, also.
I am not sure if there is a list, but the level than seems to be the dividing line between sensitive and tolerant is at about 1 ppm ammonia.

If you start cycling and see that some plants are affected by the ammonia you could try this:
Add ammonia only to 1 ppm, but do this twice a day. Never higher than 1 ppm. This will still feed plenty of bacteria.

Here are a few plant responses to NH4+
Several species of Elodea were OK up to 9.6 ppm, others were slowed by 3.2 ppm. (fishless cycle starts with 5 ppm, then is reduced to 3 ppm)
Statiotes aloides cannot handle even 1 ppm.
Salvinia molesta can handle up to 26ppm.
