Germination rate of 11year old stored seeds
Comments (2)I planted some 19 year old chile seeds this year. 2/3's came up promptly. The seeds were from chiles which were dried, put in a jar, then treated as a seasoning agent for a couple decades....See MoreHot Pepper Seed Germination Times
Comments (18)What's so confusing? In general most peppers germinate at 85-87 degrees in 10 days.(Some stuff says Bhuts like 90+ dgrees but most seeds die at about 110 give or take.) I have no idea what other plant seeds sprout at,I only grow non Bell Peppers. Depending on uncontrollable stuff they might come up earlier or latter. I get ALL varieties except wild stuff to sprout mostly within 10 days,doesn't matter if it's a Chinense or a Baccatun etc. Now if your talking about growth until maturity thats a different story all together. Some take from 2 1/2 months to 6 months to bud and ripen pods. I also don't see what difference it makes to know within a day or two why it would matter if a seed comes up in 10 days , 11 days or 7 days for that matter. It could have been a hair deeper or whatever in the soil or grew more root before popping up. It's like watching Paint dry-most of the time it dries in the time it says on the can,but every once in a while it dries a lot faster or much slower...Just because it felt like it. :) Thats why seed packs only say how long it takes to put out pods AFTER it's in the ground. If seed sprouting was exact all the time it would be on the pack too ,you would get your chart... As it is you'll only get generalities,ball park figures. Too many variables to even get more than a ballpark figure for seed germination. Which for my growing conditions,soil mix etc. is 10 days average for most everything. Thats why they tell you in general to sprout your seeds from anywhere from 3-6 weeks before planting them in your garden. Most all seeds that don't pop in 14 days get dug up and they are usualy rotten or were deeper than I thaught and had sprouted but hadn't cleared the soil yet. I might not be an expert but I do grow a few pepper plants each year(400+ varieties last season.Going to cut down this season,Honest I will...LOL). I've got going on 3000 varieties and strains of pepper seeds and I just gotta grow them all....Always room for another pot...Looks good over there doesn't it? LOL No such thing as too many peppers....See MoreHow to germinate old seeds?
Comments (7)3 - 5 year old tomato seed is not that big a deal so long as the seeds have been kept under dry, cool and relatively even temperatures/conditions. Many of us routinely sprout 3 - 5 year old seed with no different techniques than we use on 1 - 2 year old tomato seeds. For really old or stubborn tomato seeds, here are a few techniques that have worked well for me: Pre-soak seeds in a mild tea solution in the refrigerator overnight. Set the seeds in moist starter mix covering them with sand to a depth about twice the thickness of the seed and keep the starter mix consistently, evenly and continually moist. Wrap the starter tray in plastic wrap or enclosed in a plastic bag, and after a couple or three days, checking on the seeds daily to see if they have sprouted. Set the starter tray on a seed starting heat pad at 75 - 80*F to provide bottom heat. If this is not possible, set the wrapped tray in a warm spot in the house, but not above 80*F. For particularly stubborn seeds, I have pre-soaked them in hydrogen peroxide for a couple or three minutes and soaked the starter mix with water that had a very small amount of high phosphorus, instantly dissolving fertilizer like Peters or Schultz bloom booster. But that shouldn't be necessary with 3 - 5 year old hybrid tomato seed....See MoreBoosting Chances of Germinating 50+ Year Old Seeds
Comments (2)The documented record as to waking up old seeds was 50 year old seeds that were stored inside in a file cabinet at the Cheyenne, WY, precursor to a USDA station and when the tomato seeds from there were moved to Ames, IA, to the new station germination was done. I've worked with old seeds but not that old and my best is waking up 22 yo seeds of the tomato variety September Dawn. You've got one heck of a lot of seeds there at 2 oz, so lots of seeds to work with, BUT, being stored like that who knows. First, you don't say where you are in a geographic sense and that refers to whether or not the seeds have been frozen in the garage. If it were me I'd start with a couple of hundred seeds and soak them in water to which you've added some blue stuff, aka Peters or Miracle Grow, or several drops of undiluted fish or seaweed stuff if you are organic in what you do. Stir the seeds from time to time to get them to sink since old seeds are very dehydrated. The added blue stuff or fish, etc, is b/c they have a high concentration of nitrate ion and that's known to play a part in seed germination although my contacting a couple of tomato seed physiologists brought no answers where the nitrate ion acted although they agreed that it's known to help. After a couple of days in the soak sow the seeds in a good soilless mix, loosely cover the seed pan with a baggie or similar, but don't use any domes, and when they need to be watered use water to which blue stuff or the fish, etc. has been added. And then wait. It may take several months so I don't know if that matters in terms of getting anything to plant out this summer and getting maturation b'c again, I don't know where you live. In the past I've used giberellic acid and potassium nitrate in various concentrations, microwave, cold tea and warm tea, green or black on the tea, as well as a peroxide ( H2O2 treatment, and the best I've found in my experience is what I mentioned above. Back when it was still possible for non-researchers to request seeds from the USDA Craig LeHoullier and I got lots of seed sent that was low to no germinating so we had lots of seed to play with. One I remember well was the variety Magnus, which was on the cover of the 1900 Livingston catalog, Craig couldn't get anything up and I got one plant and all seeds out there now for this variety came from that one plant, but not before an amusing story about trying to get fruits from it. So why not try to wake them up, knowing that the documented record is 50 yo seed and also if you're able to plant anything out for THIS season and get lucky and get something. Other than that I'd play with the seeds starting in maybe Nov or Dec, again, depending on where you live and grow tomatoes. Carolyn...See MoreKtkets
