Since seedling formation (stage 4) was only successful in one of the four tested media, we did not conduct a statistical
analysis for the assessment of suitable conditions for seedling formation. For the assessment of suitable conditions for advanced seedling development, we calculated the relative leaf length growth rate (RLLGR) as: RLLGR = (LLn/LL0)/t, where LL0 is the leaf length of the seedlings at the final measurement and LLn is the leaf length of the seedlings at the end of the experiment, and t is the elapsed time.
