    How old is too old?

    Update 06 I took the photos on May 16 in 2018. The germination from 5 years old Nepenthes eymae seeds (stored for 5 years in refrigerator) The germination from 5 years old Nepenthes eymae seeds (stored for 5 years in refrigerator) The germination from 5 years old Nepenthes eymae seeds (stored for 5 years in refrigerator) The germination from 5 years old Nepenthes eymae seeds (stored for 5 years in refrigerator) The germination from 5 years old Nepenthes eymae seeds (stored for 5 years in refrigerator)

    Konnichiwa! I took the photo on March 06 in 2018. After I took the above photo, I sowed these seeds. It seems the old seedlings have the strength to push through their seed husk.

    Konnichiwa! Dear Whitefox-san, Thank you very much! “scarification”!…. a bit scary… Some growers remove Ibicella seed husk in my country. Jan-san (Dr. Jan Schlauer), who has been a good friend of mine since I joined the cp-listserve in 1994, answered my question. ...... Regarding the seed coat, this is the commonly used term. The external form and the mechanical properties of the seed are defined by the outer layer that is called testa. Additionally the embryo is included in the inner (protective) layer that is called tegmen and is a thin membranous peel in Nepenthes. Other seeds have endosperm that additionally surrounds the embryo, but in Nepenthes the endosperm is not well developed or lacking whatsoever. ...... Kind regards from the Far East

    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.

    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.

    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?”.

    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

    How old is too old?

    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. Kind regards from the Far East

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