Figure 2.
Trichome numbers of wild-type plants grown in the presence of uniconazol. The average number of trichomes on leaves 1 through 4 of 10 rosette plants from two independent experiments is shown for trichomes with two (white columns) or three (hatched columns) branches. Plants were grown in Petri dishes containing MSAR plus uniconazol at the indicated concentration for 3 weeks. Compared with Figure 1, trichomes had fewer branches on average, presumably because the growth conditions in Petri dishes involved increased RH. At 10−5 m uniconazol, only 5 to 10% of the seeds germinated.
