Fwd: Your recent post on freezing hosta seed {reply to Jim Hawes}

Jimbo, The Wizard of AH's,  (Mr. James Hawes nicknames) T'was my pleasure, Jim, to see you be WARM & COZY in that love-nest in de wooded hills of Maryland and "just fighting dem'BARE'S!..right?" *laugh* LOVE T'you and Edna...
THIS IS ALSO SENT VIA BCC into hosta-open & hostapix...so:
*SUB-NOTES TO hosta seedling growing lovers*
  ```````````````````````````````````To whit; a while ago, some new wannabe hosta-seedling-growers, asked some questions  related to: whether or not, freezing of freshly collected, dried & cleaned hosta seed, will sprout better after freezing for a while?
      I stated (IMHO?) that I personally believe, from what I've seen, that yes, it does help the sprouting process of freshly collected hosta seeds? <I wasn't sure about this statement?> so  I sent a copy of my email to Jim Hawes ("WIZARD OF AH'S")  whom lives in dem Mountains of Maryland; and this, has no inference to a hosta of the same name ('Wizard of AH's') recently introduced by www.robynsnestnursery.com and/or perhaps it does? <g>
      In my previous post, I wrote something like: yes!...freezing helps?..but now, after reading Jim's email below, I would like to amend my earlier rhetoric to say: "Perhaps freezing!..won't hurt? {{B>))  *dunno'fo'sure THO'* "y'all can decide yerselves" ;-))?)

<---- an original email from Jim Hawes ---->
("and this is for all you hosta-loving-folks, interested in seedling sprouting successfully; with love from Ontario & Maryland and Good'luck t'all & knowin y'all be havin a lotta fun"?..yup!)

Subject: Your recent post on freezing hosta seed

Hi Bill and Merry Christmas,

Recerntly I promised to send a copy of a past post on hosta seed which I sent to Beth Arnold about three years ago. It presented some points of view about seed technology which may be pertinent regarding hosta seed.  One should not confuse "stratification" with freezing of seed. Two different physiological precesses are involved. I hope the information provided is stimulating and helpful to your discussion.

Beth Arnold,

I have not seen a response to your post of Sept. 8 when you inquired about sowing seed that was "fresh". This touches on seed technology, dormancy in seed and factors affecting germination. I posted to Bill Nash and Carolyn Schaffner on this subject about a year ago. I will repeat parts of my post which may be helpful. It is based on information available in Botanical or Horticultural textbooks, such as "Plant Propagation", Kester and Hartmann and others. I have added comments of
my own based on my experiences.

While more research is definitely desirable to perfect hosta technologies, I believe that there is adequate practical experience to conclude several GENERALITIES about hosta germination characteristics and the appropriate technologies to maximize germination percentage and germination rates. I will attempt to summarize some GENERALIZATIONS as they fit within the Five Broad Categories or Groups of Seed Types, generally accepted by plant physiologists and seed technologists, as characterized by their response to environmental conditions and handling methods.
 Group I...Seeds with hard, moisture-impermeable coats preventing water (and gas) absorption by the embryo.
 GroupII...Seed with dormant embryos that respond to chilling   ( note: not freezing necessarily...Jimbo)  to achieve germination (Several cold/warm cycle variables may be necessary for
germination)...( note: this is also called stratification...Jimbo)
 Group III...Seeds with a combination of impermeable seed coats and dormant embryos.
 Group IV....Seeds containing chemical inhibitors
 Group V...Seeds that are dormant at harvest and become able to be  germinated  upon dry storage. Dormancy may last for only a few days, disappearing with dry storage treatment followed by moisture and warmth.
Experience already acquired has shown that hostas fall within Group V Category Seed Types. Characteristics listed under the other Four Groups (1 thru 4) do not apply to Hostas, in my opinion. If anyone has any data to prove otherwise, I would be happy to see it, however.
 Based upon the working knowledge of numerous seed growers who have  reported their experiences, several other GENERALIZATIONS can be made for hostas. I will list a few and will welcome other GENERALIZATIONS, plus any discussion anyone wishes to initiate.
 1. Germination of hosta seed is neither promoted nor inhibited by light (intensity, type, or duration).
 2  Depth of planting seed MAY influence germination percentage or rate.   Depths of approximately 1/8 inch or in a shallow furrow, appears ideal.
 3. Seed germination percentage and rate may be influenced by moisture; content of media and ambient temperatures. These two environmental variables are usually optimized thru horticultural skills and practices.  Extremes of these variables MAY affect germination adversly. Type of
medias is important.
 4. Once germination occurs, seedling growth is highly influenced by light, moisture and temperature (75 degree F is ideal). Each variable is controlled to optimize growth of seedlings. Light intensities of about 1200 foot candles is satisfactory as long as temperatures do not become excessive causing heat injury to seedlings.
 5. Photoperiods of 24 hours/day are ideal to maximize seedling growth.

 6. There are several others that could be mentioned...disease, insect control, etc. but the above should be mentioned at the very minimum as guidelines.

What should you do? Plant your seeds when dry. Any dormancy is short-term.

Jim Hawes
