TNhunter and everyone else.
If TN has inspected his seeds and found that there was no enlarged embryo growth.
Then some of the facts about embryo growth are inacurate, or the seeds were not properly or correctly stratified.
1) If seeds that are properly stratified, do not require the embryo to grow and be inlarged like the studies show.
From Ontario Ginseng Growers Manual:
\"One way to check whether seeds are developing well is to measure the embryo. Split the seed along the suture line. The embryo is in a sack at the micropyle end of the seed (the pore end). A well-developed embryo at the time of planting should be about 2-3 mm long. The embryo will grow over the winter and will be about 5mm at the time of germination. If the embryo is less than 2mm in length it may not germinate next spring but the spring after, if diseases have not broken it down by then.\"
2) Also, Guy's photos of enlarged embryo at the time of being pulled from stratification box are not true signs of proper stratification.
Or the other perspective:
Harding did not split seeds open and check for proper embryo growth. And planted 60 lbs of improperly stratified seeds and ended up with poor germination.
Perhaps those left over seeds that Harding planted in the spring were from the bottom of the barrel.
My thought is that properly Stratified Seeds must have enlarged embryo growth in order to germinate the first spring. And since Harding does not do a test, splitting seeds open and checking for proper embryo growth. The 60 lbs of seeds he planted this spring and the seeds he sent to TNhunters were not completly stratified.
I believe that Guy's summary of what the embryo should look like when it comes out of the stratifying box is correct. And the study by Ontario Ginseng is correct. If the embryo is not enlarged to a certain size then it is not completly stratified. The reason that seed start cracking open and \"smiling\" is because the embryo enlarges and causes the seed to crack and \"smile\". If the embryo does not enlarge, then the seeds are Green.
I will continue to inspect all the seeds I buy. And if the Embryo is not grown to full size, I will reject the seeds as being \"Green Seeds\".
One of these perspectives is right. Embryo growth is required or embryo growth is not required.
I've already decided which one is right.
