Phenotypic Analysis of the lep-1 Mutant in Response to ABA and GA during Germination.
(A) Seeds were incubated for 4 d at 4°C on plates with no hormones and then treated with 1 h of red light to induce germination.
(B) Seeds were germinated as in (A) but on plates containing 1 μM ABA.
(C) Seeds were germinated as in (A) but on plates containing 100 μM GA.
Germination was measured by radicle emergence. Bars = ±1 se.
