Abstract excerpt
The brownseed mutants (bs(1), bs(2), and bs(4)) of tomato all possess dark testae and deleteriously affect seed germination speed and/or final percentage. Poor germination performance of the bs(1) but not the bs(4) mutant, was due to greater impediment to radicle egress. Testa toughening (bs(1)) was prevented by drying in N(2). However, poor germination speed was hardly affected by drying. GA(4+7) did not...
