Seed Germination: Seeds stored in the refrigerator for 21 months and then sown on moist potting mix showed the first above-ground signs of germination after 16 days. A plug-in, warm germination mat was under the cups in which the seeds were planted. Seeds of accession Mione et al. 723 were collected Jun 05 and sown 12 Apr 2007 with first germination 28 Apr 2007.
