There was an entire chapter on the methodology of how to convert diploid Datura into tetraploids and more by colcisine treatment. If I remember correctly there was both mentioned the measure of CS to be applied to the seeds and a timescedule for the seeds to soak up the solution. I found it in "Blakeslee:The Genus Datura". I hope my sister in laws DH Søren has access to CS, because I have not the necessary papers to access is directly. From Datura we know that the phenotypical expression is a plant, much larger in all parts, more fast and strong growing than natural for the species. Larger flowers. Round, small pods.

Here is (unfortunately only) an example of differences in flower and fruit of D. tatula. The tetraploid specimen is on the leaf. I have two different accession numbers containing tetraploid Datura seeds. Oh, I would love take two aurea cuttings and treat one and use the other as control and measure growth rate, speed, sizes of plant parts.
