Hi everyone, I am starting to grow this genus again.
Seeds from seller A
Seeds were soaked in GA3 for 24 hours and sowed on peat/sand mix. Almost every seed of the five tropical species sown became mouldy and there was no germination.
Seeds from seller B
First batch was soaked in GA3 for 24 hours and sowed on peat/sand mix. Germination for filifolia was great, so-so for liniflora and rorida. None for guehoi and aquatica.
Second batch (with different location data) were bleached, then soaked in GA3 for 24 hours. Germination was great for rorida, so-so for guehoi and none for aquatica (did not sow filifolia this time).
Interestingly, almost all aquatica seeds turn mouldy regardless of the source! With or without bleach (used just to delay/kill the fungus), even though the onset of mould on the ones treated with bleach was later. I've sown fresh (a week old) aquatica seeds before and the germination rate is 100% but as soon as they have been stored in the fridge, it seems that the viability drops to almost zero very quickly. The other species seeds do keep much better.
Anyone has similar experience? Is there another way to sterilise the seeds? We only have the pharmaceutical grade of hydrogen peroxide here and it doesn't seem to help (I tried on VFT seeds). TIA!
