<h2>Development of Plant Needles</h2>
Explanation:
- Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.
-
In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.
-
The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.
