Dr. Deno did standardized testing. Regarding temp regimes, his aim was to determine whether a seed required warm or cold conditioning or combinations thereof. He chose 70F for the warm, 40F for the cold. In the data below:
70 = germinated at 70F
40 = germinated at 40F
40-70 = 3 months at 40F, then germinated at 70F
70-40 =3 months at 70F, then germinated at 40F
70-40-70 = 3 months at 70, then 3 months at 40, then germinated at 70F
D = dark required
L = light required
DS = dry stored
OT = outside temps
comment = specific information in book (I can look it up if you are interested)
when there are multiple entries for the same species, he had different accessions of seeds, and they performed differently.
