How long can we keep Drosera seeds?
« Thread Started on 29 Mar, 2008, 20:02 »Hi, i had just got some seeds yesterday. Actually quite alot of seeds. 1 species of drosera more than hundreds tiny tiny seeds. Do we put all the seeds in those normal plastic container or do we need to put only a few seeds? size of the container around
7 inch * 4.5 inch size only.

And how long can we keep the seeds without losing any gemination success rate?

I'm not sure, some of Neps' germination rate are rather high..
If you Neps are having highier germination rate... then you probably struggle in transplanting for them...

What is Neps did you sow? Link to Post - Back to Top LoggedDavid

« Reply #4 on 31 Mar, 2008, 9:13 »For me I will just dump all the drosera seeds in one pot and trasplant them when they germinate and is about 4-5mm in diameter. This is because I have space constrain.

I do the same for neps but I germinate them on chopped up sphagnum moss. I'll cut the s.moss to tiny bits so that I can easily remove the seedlings and transplant them when they grow up. This way the roots will not be entangled on the long sphagnum moss if you did not chop the moss up.

It is generally accepted that nepenthes seeds loose its viability very quickly if not sow fresh. However, there are growers who are able to germinate the seeds after a year.

For byblis and temperate drosera seeds, I usually keep them in plactic containers or plasctic ziplock bags in the refrigerator. According to experts the seeds looses it viability in room temperature. However, never keep nepenthes seeds in the refrigerator.

Generally, my nepenthes seeds germinate faster than my drosera or byblis seeds. I think other growers also have this same experience. Sometimes drosera seeds will only germinate after 6 months. So do not throw away the pot if they do not germinate in a few months time. « Last Edit: 31 Mar, 2008, 9:19 by David »Link to Post - Back to Top LoggedMy Wantliststrath76

Hehe.

Drosera seeds should keep without to much loss of vogour for a period of a year or more provided they are stored in an airtight container/bag and kept in the fridge.

I have kept seed in this way for periods greater than 12 months and still had good success. Nep seeds are different and should be sown when fresh. The longer they are kept the harder it becoes to germinate them.

I have read that older seed can be treated with Giberallic Acid to promote germination but I have not tried this myself. All seed should be stored in cool and dry conditions to prevent them from going stale.

Re: How long can we keep Drosera seeds?
« Reply #6 on 31 Mar, 2008, 11:44 »Alright, thanks for the advice. I had modified my indoor 4 ft Aquarium stand, and also bought alot of trays and modified the lightings. Therefore i have alot of spaces. I had already sow all the seeds. Drosera & Neps.
Using only horti peat moss.

Lighting is 3 pieces of 4 ft Flourescent extra bright(philips green pin cap). 4 or 5 inches from the plants.

Humidity i don't know how to count. But should be high, i sow the seeds in plactic container with only 2 * 3mm(diameter) of holes for air.

The plants are planted in an air cond room(only at night).Air circulation in the room is ok, because i leave the toilet door and window open 24/7.

Any comment?

« Reply #8 on 31 Mar, 2008, 12:36 »Hey,
I agree with what David said. I have bought seed that was 2-3 years old and it germinated just fine. The owner said that he kept it in a refrigerated room and he has had success with seeds 10+ years old. I don't know if he was exaggerating a little, though.
happy growing,

Better late then never. The viability may have been affected to some degree but it is better to store them correctly from now until you sow them rather then leave them out. Link to Post - Back to Top Loggedpheabs

« Reply #12 on 1 Apr, 2008, 3:54 »for drosera seeds, if you're not sowing them immediately, you can store them in the fridge. i usually store them in the veggies section.

but for byblis seeds, storing them at room temperature in a dark drawer is fine. i have no idea why but fresh byblis do not germinate well for me and the germination rate goes up after the seeds were left in a drawer for about 1-2 months. unless you are not going to sow them within the next 2 months, then you should store them in the fridge.

« Reply #13 on 1 Apr, 2008, 9:42 »hongrui, I have the same experience too. Fresh Byblis seeds do not germinate that well for me too. Usually, I'll store them in the fridge a couple of weeks, then take them out and place them outside the fridge at room temperature for 1-2 weeks before sowing them. Seem to germinate better this way.

Re: How long can we keep Drosera seeds?
« Reply #15 on 1 Apr, 2008, 12:34 »David / hongrui : i guess ageing the byblis seeds somehow helps with the stratification requirement. nowadays, i just let the seeds drop from the mother plant & altho the germination rate is low, i still do see plantlets coming out. Maybe about 10-20%. Link to Post - Back to Top Logged

btw, what if the seed of the drosera i kept was in a container which are not airtight ?
cause the seed was been like that around 1 week, before i seal it & place in the fridge, will it still be germinate after a period i only took out for planting?

[Marigoldsfail21]

It doesn't have to be airtight. It actually might be better to keep them in a container that allows airflow so the seeds are less likely to mold.

=.=!

i already seal the hole which was locate at the container & stored the seed in fridge.

Is there any necessary to un-seal it back?

[strath76]

You shouldn't need to remove the seal on the container. The reason that it is suggested to use an ait tight container is to stop moisture entering container, which could then lead to mould. If your seeds have been dried out (If they have been left out for a week they will have dried out) then you wont need to worry about it. I store mine wrapped in paper in a zip lock bag. The paper gives a secondary defence against moisture. I then put the whole lot in the fridge unitl I am ready to sow them. I have just sown some Sarra seeds that are 2 years old and they germinated in about 2-3 weeks.

[Marigoldsfail21]

It doesn't matter too much really, it's just that mold likes stagnant, moist conditions, so if there is enough moisture in the container for a long time, it can condense a little and mold can develope over time. That's why I just like to leave my seeds in a paper envelope in the fridge, so there won't be any water condensing and moisture getting onto the seeds. (And drosera seeds don't usually have to be stratified)

Now having a sealed container might be a good thing if there wasn't any chance moisture would be in there. For example, ig you used silica gel packets in a sealed container with the seeds, you could have the seeds last for a longer time maybe, since then there would be very little moisture within the container.

Wow I take a long time to post. Haha Strath, your post wasn't there when I started typing.
