No statistically significant difference (Student's t test, P > 0.4) was detected between the marked genotypes.
‡
Statistically significant difference (Student's t test, P < 0.05) was detected between marked genotypes.
*
Number of secondary inflorescences in plants that ceased secondary inflorescence and branched flower production prior to node 20.
&
% of plants that formed more than 20 secondary inflorescences and branched flowers. Plants were grown on soil at 22°C in long-day conditions (LDs; 16h light/8h dark, ~ 110 μmol/m2/s).
