Other claims from this paper (8)

Intervention effect Colchicine-treated seeds of diploid marigold Jinxiu No.1 showed a thickened hypocotyl after germination.
Mechanism The stem of the M7 polyploid became thicker owing to the expansion of stem cells.
Observation Flow cytometry confirmed that the M7 line was a pure tetraploid.
Observation The M7 tetraploid line had significantly enlarged ligulate petals.
Observation Under scanning electron microscopy the cells of the polyploid were clearly enlarged.
Observation The polyploid had increased flower diameter and fresh weight per head.
Observation The lutein content in marigold was significantly increased.
Observation The highest lutein concentration was found in the darker petals.
