Morning Glories: Frank's experiment #2, 1 by fchilders

This little experiment was designed to determine if Iodine in very low concentrations could be valuable as a good soak. These data do not reflect an growing out of seeds tested and only reflect the success of soaking the seeds without any rotting away in extended film soaking in petry dishes. The growing out woud of course be a necessity in the long run to determine if Iodine injures the hypocotyl in any way.

I used two species in this experiment. I. purpurea and I tricolor (two sources and two colors

This experiment includes 2 species, therfore it is in two parts.

Part one, I. purpurea, is divided into two plates.
Plate #1, Distilled water as a film in petry plates, with I.purpurea seeds. After
9 days mold appeared
Plate #2 1%iodine solution as a disinfectant with same specie
After 13 days the plate with 1% iodine did not have mold. Enough
for me.

Part two, I.tricolor is divided into two plates with the seeds from two origins.
Plate #3 Flying saucers, .5% iodine, no mold at 13 days
Plate #4 Dark blue, .5% Iodine, no mold at 13 days.
Excellent germination in bothe plates. Chlorophyl, yahoo.

Conclusion: Iodine at .5% is a good disinfectant for a seed soak. Unsolicited revelation, is that in a two day soak of .5% iodine, the I.tricolor seed coat is completely unzipped and unjacketed and ready for uneventful germination. See pictures.. Frank
