FlytrapCare Carnivorous Plant Forums

I sowed a batch of home produced N. rafflesiana seeds. From germinated seeds so far, a quarter of the seedlings have 3 cotyledon leaves instead of 2.
Of seeds from other sources I sowed in the past, this has been very rare. This female raff was pollinated with other males before. No seedlings showing the trait.

The high occurence of 3 cotyledon seedlings prompts me to believe that this pair of parent plants could be carrying a recessive gene leading to this phenotype. Anyone know what effect this trait brings about? Other than a minor anomaly at seedling stage.

Not so much about the cotyledon, but just a photo of the same seedlings at 9 months old.

Some start to show nice red tint on the leaves.
The largest one at top right is actually raff x gracilis. Hybrid vigor makes it grows faster than the true rafflesiana.

This isn't an altogether uncommon occurrence. When sprouting cacti, I usually find a few seedlings with 3 cotyledons. As far as I know, it is just a random occurrence. It has not had an effect on my Hylocereus or Carnegiea that had three cotlyedons. I doubt it is genetics, as I've never seen evidence of it being genetically transferred.

By the way, those seedlings look great!
