PofW_Feathers Posted March 3, 2018 Report Share Posted March 3, 2018 Konnichiwa! First of all, I am not a Nepenthes enthusiast, but I like Nepenthes. I am quite unfamiliar with Nepenthes. In fact, I have been hardly growing Nepenthes in greenhouse. I remember the disappointed look (facial expression) of the great German Nepenthes & Heliamphora specialist, who is a worldwide distributer, when he saw a dying tiny Nepenthes (only one I had in my greenhouse at that time) in my Byblis greenhouse (see the far bottom in the page 1 of the thread: http://icps.proboards.com/thread/2348/scented-byblis?page=1 ) after the ICPS international conference in 2002. Back to the subject, My German friend (not the above-mentioned specialist, but he is also a specialist) kindly sent Nepenthes eymae seeds to me in 2013. I sowed the seeds in vitro, they germinated very well. Recently when I was tidying up the refrigerator, I found the remaining of the seeds without silica gel. Just curiosity, I sowed the seeds on February 9 in 2018. The seed was 5 years old. I noticed its germination a few days ago. I took the photos on March 2 in 2018. I have often heard the viability of Nepenthes seed is quite short. It might be the fact when it came to the Lowlanders? What is your experience? Kind regards from the Far East the germination from 5 years old Nepenthes eymae seeds the germination from 5 years old Nepenthes eymae seeds the germination from 5 years old Nepenthes eymae seeds the germination from 5 years old Nepenthes eymae seeds the germination from 5 years old Nepenthes eymae seeds Quote Link to comment Share on other sites More sharing options...

PofW_Feathers Posted March 3, 2018 Author Report Share Posted March 3, 2018 Dear Werds-san, Konnichiwa! Thank you very much for the reply! I must say the seeds/seedlings are definitely Nepenthes. I recommend you to edit your reply before I quote your reply. O.K. I will post the update. Kind regards from the Far East Quote Link to comment Share on other sites More sharing options...
manders Posted March 3, 2018 Report Share Posted March 3, 2018 I also dont think they are nepenthes. Quote Link to comment Share on other sites More sharing options...
Whitefox Posted March 3, 2018 Report Share Posted March 3, 2018 I had seeds that germinated one year later after being sowed in a pot, but I guess that the way they are stored can determine how long they can survive before germination. 1 Quote Link to comment Share on other sites More sharing options...
PofW_Feathers Posted March 3, 2018 Author Report Share Posted March 3, 2018 Dear Manders-san, Konnichiwa! I believe you are a great Nepenthes specialist in The United Kingdom of Great Britain and Northern Ireland....... O.K. To all, Don't reply about my seedlings, When I post the updates, you will know. Just reply about your experience. Dear Whitefox-san, Konnichiwa! Thank you very much for your experience!!!

manders Posted March 3, 2018 Report Share Posted March 3, 2018 Well if your sure they are then they could be, some types lack he wings that most have. I’ve had hem germnate after a about 1 year after sowing, thats kept wet and in typical highland conditions. 1 Quote Link to comment Share on other sites More sharing options...

Whitefox Posted March 4, 2018 Report Share Posted March 4, 2018 Well at first glance they don't look like Nepenthes seeds to me neither, but it is as easy as waiting for the first true leaf to grow, right? A German Nepenthes and Heliamphora enthusiast and distributor... perhaps are you talking about A. Wistuba? Quote Link to comment Share on other sites More sharing options...
werds Posted March 4, 2018 Report Share Posted March 4, 2018 (edited) Why would i edit my comment in first place? I can´t give my opinion? They don´t look like Nepenthes germination for me based in photos i see of Nepenthes seeds germination, I think i´m free to doubt your photos, i´m not saying that they aren´t Nepenthes...

Dear Werds-san, Konnichiwa! Yes indeed! You are right! Could you please share your opinion about "How old is too old?"?

PofW_Feathers Posted March 13, 2018 Author Report Share Posted March 13, 2018 (edited) While waiting for the update02, I am not sure it is an appropriate thing species being categorized as Lowlanders, Intermediate or Highlanders, so far as the seed viability. But, among Lowlanders, the appearance of N. northiana seed is significantly different from N. ampullaria. We probably should consider to separate N. northiana from the amp/raff/bical group. What do you think of it? I am trying to grow N. northiana from a few sourses. I feel N. northiana seed viability is a bit longer than I expected. Another N. northiana seeds I obtained in April, 2016. I sowed them in the plastic container immediately. They started germinating on May 02 in 2016. I sowed the remainder of them in vitro on April 10 in 2017. I had stored the seeds in the refrigerator, no silica gel. I did not remove the seed husk in this case. They started germinating on June 10 in 2017. Please see attached photos, you can see the seed husks. Although they are neglected, they still look healthy, imo..... I took the photos on March 13 in 2018.

manders Posted March 14, 2018 Report Share Posted March 14, 2018 Whether they are lowland/intermediate highland, does not imply a genetic relationship, its purely to do with growing conditions. 1 Quote Link to comment Share on other sites More sharing options...

PofW_Feathers Posted March 15, 2018 Author Report Share Posted March 15, 2018 update 02 About storage, My thought for the moment, 1: the seeds should be high quality in the first place. 2: cold storage is necessary. 3: keep or control the seed moisture content (IMPORTANT) 4: inhibit propagation of bacteria and fungus 5: something I have no idea Quote Link to comment Share on other sites More sharing options...

PofW_Feathers Posted March 28, 2018 Author Report Share Posted March 28, 2018 (edited) Konnichiwa! While waiting for the update04, I took all photos on March 28 in 2018. I have been confused about the opinion that is the cold storage damages Nepenthes seeds. The other experiences that contradict this opinion, though much shorter period than N. eymae (storage for 5 years in refrigerator). I sowed N. aff. truncata seeds in a plastic container in August 2016, though they(plants) still have been neglected in the plastic container. I stored the remainder of the seeds into the refrigerator, with no silica gel. I sowed them in vitro on March 6 in 2017 (> 6 months old). I transplanted them once. Please see attached photos. N. aff. truncata in vitro(from the seeds stored for > 6 months in refrigerator) N. aff. truncata in vitro (from the seeds stored for > 6 months in refrigerator) N. aff. truncata in vitro (from the seeds stored for > 6 months in refrigerator) I got N. peltata seeds from my friend on March 28 in 2017. I sowed almost N. peltata seeds in vitro on March 30 in 2017. Please see attached photos Nepenthes peltata in vitro Nepenthes peltata in vitro Nepenthes peltata in vitro The seed appearance resembled, if anything, N. northiana & N. suratensis. Please see attached photo The seed husk of N. peltata. I stored the remainder of seeds (very small numbers) into the refrigerator, with no silica gel. I sowed them in the plastic container on February 9 in 2018 (10 months old, stored for 10 months in refrigerator). Please see attached photos. Nepenthes peltata (from the seeds stored for 10 months in refrigerator) Nepenthes peltata (from the seeds stored for 10 months in refrigerator) Nepenthes peltata (from the seeds stored for 10 months in refrigerator) Nepenthes peltata (from the seeds stored for 10 months in refrigerator) Nepenthes peltata (from the seeds stored for 10 months in refrigerator) My question is “How long does the cold storage damage Nepenthes seeds?”.

PofW_Feathers Posted April 2, 2018 Author Report Share Posted April 2, 2018 Update 04 Konnichiwa! If you agree to my claim that these seedlings are Nepenthes, please share your experiences or your opinion about "How old is too old?". I think nobody denies your experience even if it would be contrary to common belief. At least I never deny your experience. Kind regards from the Far East I took all photos on April 02 in 2018.

PofW_Feathers Posted April 4, 2018 Author Report Share Posted April 4, 2018 (edited) Konnichiwa! Is there anybody being familiar with the technical terms? I call what I removed the Nepenthes seed husk. Some members on TerraForums, where I am stubborn, arrogant, and...., call it the Nepenthes seed coat. TerraForums The membrane that I provisionally call the seed coat still wraps the actual seed, except the one end where the root will be emerging. It still seems to protect the seed. I illustrate it by using the peanut though it is improper. Could anyone explain the technical terms? Kind regards from the Far East Nepenthes eymae: the part that put a red ring around, the membrane doesn't exist originally there. Peanut: the part that put a red ring around, I artificially removed the coat. Edited April 5, 2018 by PofW_Feathers Quote Link to comment Share on other sites More sharing options...
