Extractability of gibberellin-like substances from tulips grown at two temperatures in either the light or dark






Acta Horticulturae (47): 297-305

Extractability of gibberellin-like substances from tulips grown at two temperatures in either the light or dark

Bulbs of the tulip Paul Richter were rooted and cooled for 15 weeks at 9 deg C in the dark. After an initial sampling, batches were transferred to either continuous light or dark conditions each at either 9 or 17 deg for one week. Compared with dark-grown bulbs, light-grown bulbs showed a greater increase in shoot fresh weight. However, the scapes were longer in the dark. The highest GA-activity was found in extracts from plants grown in the dark at 17 deg.

Etiolated shoots of dwarf Meteor pea converted [3H]GA9 into GA20 and 2,3-dihydro GA31 more readily than did shoots of light-grown pea seedlings. The conversion of [3H]GA9 into very polar acidic gibberellins was unaffected by light. The interconver...
