Abstract/OtherAbstract:
|
Seedings from a single lot of Digitalis purpurea L. seeds were germinated in batches over a period of 13 months. A total lipid extract was made which was resolved into esterified and unconjugated plus glycosylated sterol fractions. The amounts of sterol in each fraction and in the total were compared for seedlings germinated at different times of the year. The amount of esterified sterols reached a maximum value from March until June, and a low value from July until January. In January, a sharp increase began which lasted until March. Amounts of unconjugated and glycosylated sterols were elevated from March until June, low from July until October, and on the rise from November until March. These data correlate with an annual cycle in seed germination. The phase of maximum sterol content of seedlings is followed by a period of null germination. |
