Any chemistry nerds out there?

Tried feeding the entire fruit to a large flightless bird in Mauritius, then collecting its shit?@mrundkvist I don't fly and it's a really long way to Mauritius by land. Got any other chemistry hints on my question?

@lionelb Not sure I'm following you. The point of scarification is to degrade the seed coat so that water can enter the seed (imbibition). Are you saying that chemical scarification is not possible or are you just saying that it is not possible with a weak acid?
I suspect that it will either be ineffective or that it will be so slow that the process will be qualitatively different. Only experiment will show.
Failure to germinate could be either failure to impact the layer or because of inactivation of the seed by penetration. An alternative reliable method applied afterwards would confirm which of those.
I am just suspicious of the idea that increasing the contact time would achieve equivalence.

Maybe try it the natural way - eat them and shit them out! Isn't that how it works in nature?

@EvilCartyen It is and and I am reminded of it eerytime I talk about the topic, because the joke inevitably comes up! @pms @folfdk

@lionelb Great, this is why I'm asking. I curious if you have any theory as to why you think increased contact time could achieve equivalence. I might learn some chemistry.

@pms This is an interesting idea. Any links on how such an aggregate looks like?

@pms I sand, clip, file and also bury some seeds for a whole year depending on the species. Would your colleague sand Cornus mas too? I would be happily surprised if that worked. The seed coat is really tough.

@malte the seeds we discussed was wild pea seeds, pretty tough seed coat too. The sanding device is home made by another colleague. A box for the seeds and sandpaper fastened to a bit of some sort.

@pms Sounds like a realistic DIY project. I'm curious how it looks like. If you get a chance to ask your colleague for tips on how to make one, I'd love to hear.
