This is a discussion on Sowing is an odd thing within the Breeding & Hybridization forums, part of the Orchid Propagation category; ...
I often receive the information that sowing is odd and boring. Sitting at the clean-bench for hours of time and being unable and locked out to get delighted by buds, flowers or dead bugs.
Let me show you what does fascinate and fascinated me such a lot once that I abandoned keeping orchids in a greenhouse and focused keeping them in flasks. It’s the microcosm which has captured me and never sets me free again … . I hope Him God above can care for a clean-bench, too, when I am gone.

Wow! I flunked sciences and I have little idea of what exactly I'm looking at , but this is cool to see.
orchid-seeds, seed-embryos and beginning germination with rhizoids at the protocorms
Beautiful pictures. Thank you for sharing.
many thanks for sharing these, i had always been wondering what is happening in that small bottle..........
i love the second and the third pic,,,,,,,,way too cool !!!!
These are great photos...thanks for sharing them.
Wow. These photos are extraordinary!
Pretty thanks for your comments. Yes, this is the moment when life starts. And I am fascinated having these moments here daily. Actually we care for about 1.250 different orchid-species in propagation. This means many millions in plants and it is almost a fulltime-job but requires no greenhouse, no watering, just checking regularly which plants needed a replate, for which it is better leaving them where they are. Laboratory work only ... but it really is fascinating. Just 5% of our capacity is reserved for hybrid-sowing, we don´t do more.
Sometimes the development of chlorophyll happens very fast, within a few hours only and the entire medium gets green. Normally it takes 4 - 6 replates within the 2 years we have the seedlings inflasked. Some finish earlier, like Thelymitrae, Disas, some Phalaenopsis which usually grow inflasked like weed. For some even 2 years are too short measured in time. Over the different medium-recipes one succeeds in steering the plant - forcing it to produce more roots, supporting the growth of the shoot, caring for more young shoots, larger leaves or shorter ones and so on. We also developed a medium plants stop in growing and fall into a kind of rest what is important in order to delay the seedlings´ development without letting them starve. Over that one can wake them up by transferring them into another medium whenever there´s the need doing.
Consider both, that the orchid naturally calculates of requiring a mykorrhiza for a successful germination and that therefore (as the chance is low the seeds will meet this special fungus) the orchid produces thousands until millions of seeds per pod. The a-symbiotic way of propagating orchids means a high chance that every seed-corn will germinate provided the seed-quality is ok (what often can only be provided by an out-cross). This means further that generally seen it takes only 1 successful sowing per species which is – for instance – highly endangered in the wild. And if the sowing is successful and seedlings can be wisely spread among skilled cultivators the plant is safe in its existence and diversity even when it doesn´t succeed anymore re-establishing it into the wild where it occurred once. This and some more is part of a conservation-program.
So what I want to express, don´t accuse people clearing rain-forests I the wild only. Each of us is responsible for the conservation, even it takes place as an ex-situ conservation only and one is aware of the fact that we cannot re-estabish the plants anymore. The major reason why re-bringing the plants to original habitats doesn´t work anymore or is very restrictive in being possible is the lack of the natural pollinators which often are quite more endangered or even wiped out than the orchid is itself.
Generally seen there a 2 methods of conserving orchids, the one is doing it generatively by sowing seeds. The other is caring for a tissue-culture. The first way cares for a sufficient diversity of clones. The second shall be kept as an emergency-path only which shall be entered when just one single plant is left, cannot be self-ed and it is needed to propagate it in order to reduce the risk losing the entire species by losing the single plant.
I am pretty sure everyone from you owns the one or the other orchid which is precious, rare, unusual. I would recommend to take a pollen from the flower once and store it by freezing. Orchids don´t like to get to self-ed, most don´t even develop viable seeds then. So the best way is always caring for an outcross. And this would mean acquiring at least 2 clones of a species right from the beginning. But who does? It isn’t sure a rare plant can ever be replaced in one´s collection at all. But by conserving the pollen you have at least the essential part of the clone conserved being useful even to a time the plant doesn´t exist anymore.
they are my favourite, thanks for the post.
