Other claims from this paper (8)
- Observation Maize populations differed significantly in 2C DNA amount, from 4.62 to 6.29 pg.
- Association Differences among populations account for 36.15 % of the inter-populational variation in 2C DNA amount.
- Observation Genome size varied 1.08 to 1.63-fold within populations.
- Observation Knob heterochromatin percentage varied among and within maize populations.
- Observation Knob number, chromosome position and sequence composition varied among and within maize populations.
- Association A positive but non-significant relationship was observed between genome size and knob heterochromatin percentage.
- Observation Length of the vegetative cycle was positively correlated with the percentage of heterochromatin.
- Mechanism Heterochromatin may have an adaptive effect on maize vegetative cycle length through selection.
