while freezing seeds that were soaked three and six hours respectively 

 greatly reduced the total ; the 3-hour soaking far worse than the 6-hour 

 soaking. Etherizing dry seeds and etherizing those soaked three hours 

 seemed to give about the same results in germination, while etherizing 

 seeds that had been soaked six hours seemed to reduce the amount of 

 germination. However, the best results were only equal to the check or

untreated seeds, so apparently etherizing this species is neither beneficial 

 nor particularly harmful. 



Soaking dry-frozen seeds for six hours apparently has about the 

 same effect as soaking alone for three hours. However, where such 

 seeds were etherized for twelve hours, they gave a higher average 

 total germination than similar seeds etherized for twenty-four hours.
