Propagation Ariocarpus fom seed

[oriky]

Seedlings in 3 pots are Ariocarpus bravoanus, sown seeds on 17th July 2014. Seedlings of bravoanus grow slowly.
They were repotted once into 10 cm square pots. I kept them under weak sunlight and forced to etiolate slightly.
I will give them a normal sunlight strength and will repot in September.

Hi Frank.
Why the seedling have pink spots?

G'morning oriky,

Why the seedling have pink spots?

Etiolated juvenile tubercles of bravoanus seedlings are turned to pink colour. Since they are juvenile tubercles, they will disappear in future.

Other species show different colours. I attached a photo of fisseratus seedings for your information.

Thanks for the answer Frank, is it's common character of bravoanus?

a lot of my seedlings are showing different colors (see attached)
I try to understand what is the cause, if it's stress (you mention that red color of seedling indicates stress and the seedling takes 2-3 month to recover from those stress) or it's something else.
what do you think?

G'morning oriky,

The first seedling is mix of GODZILLA, CAULIFLOWER and crossing of those two. The second picture are scapharutros.

I think 1st photo shows healthy seedlings. They are just etiolated slightly.

2nd seedlings show an abnormal colour.
I have Ariocarpus scaphirostris but it is same species on your photo.
Your seedlings show dark green and pink. Dark green parts may be recieved too strong sunlight but some parts are pink.
I am not sure unfortunately.
