gloxinia seed germination
I have been experimenting for the first time with planting gesneriad seed, had some interesting results and would like to hear from others.
I prepared two jars with regular 'sterile' seedling mix from the store, and one of these I sterilized in a boiling water bath for 30 minutes. The medium in both jars was otherwise identical, and had been treated with a mild fertilizer. After surface sowing the seed, the jars were sealed and placed under flourescent lights.
Here's the interesting part that I would like some comment on: The non-sterilized jar germinated abundantly, about 10-14 days sooner than the sterilized jar. After the sterilized jar finally germinated, it quickly outpaced the other jar, which appears stunted in comparison. Has anyone else seen results like this? I am prone to usuing the sealed jar method/sterilization because I also work with orchid seed.
Here's a pic of the two...
