Seed Germination
Out of the refrigerator

8/25/13 - Everything got moved out of the refrigerator.  Hopefully will get some quick germination so I can move the seedlings outside before winter.  Three species have already germinated in the refrigerator - Camassia leichtlinii, Leopoldia comosa, and Eremurus stenophyllus.

GA-3 Treatment too long?

All the gentian seeds I received were subjected to 10 days of GA-3.  I suspect that 10 days may not be the optimal time for all species, since the growth on some species seemed very poor.  In particular, with Gentiana acuale, the growth was very slow, and eventually all seedlings died.  G. verna did not do well either, with few seedlings surviving.  G. newberryii and G. cruciata had some plants that look very strong, and others that appear spindly.  I suspect that the GA-3 may have adversely affected some of the seedlings.  Seedlings that didn’t take up as much GA-3 may have done better.

The next time I raise gentians I’ll try to stagger the GA-3 treatment to try  to optimize the time for the species.  Another possibility is that the seedlings died from too much water ( or not enough), particularly since two species seemed to die off.  All species received about the same amount of water.  Further analysis is needed.

Melica imperfecta

3/31/13 -  Seeds placed in refrigerator on a damp paper towel.   Estimated at 400 seeds.

8/25/13 -  Removed from refrigerator

9/4/13 - Two seeds have germinated and have been transplanted.  Several other seeds appear swollen - I expect more to germinate soon.

Eriogonum umbellatum var nevadense

3/31/13 -  Seeds placed in sunny window on a damp paper towel.   69 seeds total.

Eremurus stenophyllus

3/31/13 -  Seeds placed in sunny window on a damp paper towel.   9 seeds total.

5/15/13 -  Moved to refrigerator

8/25/13 - Removed from refrigerator.  I have a seedling that I just transplanted.  No other seeds have any sign of germination.

Rhodothamnus chamaecistus

3/31/13 -  Seeds placed in sunny window on a damp paper towel.   47 seeds were treated with GA3, 51 seeds were untreated.

4/8/13 - Twelve seeds moved out of GA3.  No seeds have germinated.

4/10/13 - Twelve more seeds moved out of GA3.  No seeds have germinated.

4/12/13 - Twelve more seeds moved out of GA3.  No seeds have germinated.

4/15/13 -  Nine more seeds moved out of GA3.  No seeds have germinated.

4/21/13 - Several seeds have germinated, both GA3 treated and untreated.

Cistanthe umbellata

3/31/13 -  Seeds placed in sunny window on a damp paper towel.   Many seeds.

5/31/13 -  Moved to refrigerator

8/25/13 - Removed from refrigerator.

8/27/13 - Many have germinated.  So far 18 have been transplanted - very low germination rate.

Leopoldia comosa

3/31/13 -  Seeds placed in sunny window on a damp paper towel.   8 seeds total.

5/31/13 - Moved to refrigerator.

8/25/13 - Removed from refrigerator, and I have six seedlings that I just transplanted.  75% germination

Camassia leichtlinii

3/31/13 -  Seeds placed in refrigerator on a damp paper towel.   14 seeds total.

7/1/13 -  Seeds have germinated.  Need to stay cold for another two months.  I’ll probably plant them and keep the potted seeds in the refrigerator until September.  Don’t think that the timing is great for this one.  I’ll have seedlings in mid-September…..

8/27/13 -  14 seeds and 14 plants - 100% germination!  Transplanted today.  All seedlings look strong and healthy - with long green blade.  Hope to move them outside in another month.

Armeria alpina

3/31/13 -  Seeds placed in sunny window on a damp paper towel.   9 seeds total.  Peeled off coat on all except four seeds.
