Kiwano Posted June 7, 2014 Report Share Posted June 7, 2014 (edited) Hi, Today is a festival in my terrarium. Why ? Because, after many acharnements, I have succeeded to do germinate some Codariocalyx motorius seeds, or telegraph-plant. All I can say it's that the germination rate is relatively low since, on ten seeds, four have germinated only. Here you have some pictures of the seedling, with some explanations. 13/05/2014 16/05/2014 24/05/2014 02/06/2014 For those who want to know how I've done : - The seeds have hardened 3 or 4 days in water, kept hot (25°C-30°C). - After that time, I observed that some seeds (fairly low, maybe 25%) swelled. But, at the contrary to what I knew, no sprout is appeared. However this swelling translated a water penetration inside the seed, so a begining of germination... I supposed that the integuments was too much tough, too much resistant to be perforated by the sprout. So I processed by a scarification with the swelled seeds (I cut volontary a part of the integuments, with precision not like a beef). In less than two days, four sprouts are appeared ! - I've transplanted the sprouts on a substrate composed with peat and sand (60%/40%). All of this has been placed inside my lowland terrarium, so approximatively 80% of hygrometry night and day, 30°C the day and 23°C-25°C the night. - I should separate all the young plants in several pots now. But I know that this specie is hard to transplant because you must take care of its roots. In all cases, I already could observe many movements of the plants. They stay slow and you must not hesitate to look a long time if you really want to see. The movements are not continuous. The leafs subside or straighten all the time.

mantrid Posted June 7, 2014 Report Share Posted June 7, 2014 I grew some of these a few years ago. They germinated without any pre-treatment, but like you germination rate was low. Lost them shortly afterwards when the plastic green house i had them in blew away. Nice to see you are having success with them, they are a fascinating plant. Mine had longer narrower leaves than yours at that stage Quote Link to comment Share on other sites More sharing options...
Kiwano Posted June 8, 2014 Author Report Share Posted June 8, 2014 Yes I was surprised concerning the form of the leaves. I've already saw a very big specimen in the botanical gardens of Caen and its leaves was really long compared with those of my specimens. I suppose it's due to the age of the different plants. Maybe young plants have rounder leaves than old specimens. I ask myself if the germination rate could not be higher if we scarify the seeds before their immersion in water...
