These pictures are a bit late, but better late than never. They are an update of the growth  progress of arabidopsis in varying amounts of D2O. The group shot is inconsistent with the others because the sample captured for 0% D2O (DDW, deuterium depleted water) is different than the sample used in the individual 0% D2O image.

With that said, there are a couple morphological things I would like to point out. In my opinion the plants are growing better (bigger, faster, etc) in 10% D2O than they are in DDW. They also appear to be slightly more green. And finally there are little hairs on the leaves that seem to be more prominent than in the other samples.

Meanwhile, in 60% D2O the plants are very yellow in appearance. It is interesting that more plants sprouted in that sample, but they are significantly behind in development.

I’ll update tomorrow for the weekly update. And this time I’ll upload the images in real-time. Promise!
