Complete removal of seed coats for prompt germination
Comments (14)TreeDazzled, I tried sugar pine seeds from Schumacker last spring. I only purchased a trial packet so I only had a handfull of seeds to work with. I placed them in moist milled sphagnum moss in my fridge crisper drawer for the designated amount of time recommended by their website. Also, I cleaned the seeds off from the ridiculous amount of mould once a week or so. No removal of seedcoat, scarification, or any special treatment. I believe out of about a dozen or so seeds only about two didn't grow. By this past fall I had about 10, 8" sugar pine babies! Sadly, the rabbits ate them all during the winter months. I was quite upset to say the least. Good luck with Schumacker, I've ordered from them a few times before with excellent results in all instances....See MoreAraucaria cunninghamii - Hoop Pine
Comments (3)On the subject of germination, I just thought to dip into a book I own, 'Seeds of woody plants in North America' by Young & Young, revised edition, Dioscorides Press 1992. It has a ton of information about Araucaria seed. You should try to find it in a library, but just in case you can't it includes the following points: 1. viability is generally short-lived, but A. cunninghamii is the species that best tolerates desiccation of seeds, viable at moisture content down to 2% whereas some other spp. won't survive desiccation below 25%, with an intermediate group of spp. not below 12%. Cool storage prolongs seed life. 2. no pre-treatment is required. "Under suitable moisture and temperature conditions (20 to 30 deg C), germination may begin about 10 days after sowing." I suspect the most important question is, how good is your seed, and is it sufficiently fresh?...See MoreTree seed viability over time
Comments (5)My GUESS is that if Acer triflorum seed is stored cold (around 41 F / 5 C) and dry it still is viable after 5 years. Acer triflorum has a very thick seedcoat which protects the actual seed. Liriodendron: it belongs to the genus Magnoliaceae. Seeds from the species Magnolia (like sieboldii, virginiana, tripetala etc.) do not store very well and are best sown not too long after harvest. When it is stored it should be cold AND moist (in moist vermiculite or spaghnum moss or something like it) I don't know if this is also the case for Liriodendron tulipifera. Maybe I should search the internet to see I can find any reliable information on this. Another thing to take into account is provenance. Seed from stand-alone trees hardly ever gives viable seed. Ideally seed should be from a stand with dozens of Liriodendron trees....See MoreZinnia seed viability -- ZenMan?
Comments (54)Hello javiwa, " ...how does a layperson determine whether a flower/plant is a F1 or non-F1 hybrid? " If it is seeds, that is usually printed on the packet, because F1 hybrids (F1) cost considerably more than open pollinated (OP). If it is plants, that should be also on the little tag that comes with the plant. Also, you can ask here. " Profusion and Short Stuff appear to be the recommended zinnias that aren't susceptible to fungal diseases. " All zinnias are susceptible to fungal diseases !!! The Profusions, Zaharas, and Pinwheels (Zinnia marylandicas) are immune to Powdery Mildew, but not to other fungal diseases, bacterial diseases, viral diseases, phytoplasma diseases, nematodes, or what-have-you. Powdery Mildew is species specific (Lilacs, Phlox, Zinnia elegans, etc, have their own species of Powdery Mildew, and the Zinnia marylandicas are a new man-made species with 46 chromosomes, and don't have their own species of Powdery Mildew yet. So they are immune to PM. It is just a matter of time until Powdery Mildew mutates and the Marylandicas won't be immune to it any more. But that might take a very long time (centuries or more) until that happens. Or it could happen tomorrow. Wait and see on that. " I'm afraid I don't have the time to cross and hybridize zinnias, as my focus is on raising butterflies. " Crossing zinnias to create your own hybrids can take as little time as you wish. You can transfer a lot of pollen in a few minutes. Ot it can take a lot of time, like in my case, where it has become a year-round hobby. Zinnias differ a lot in how much nectar they produce, so there is such a thing as "butterfly-friendly" zinnias, that produce a lot more nectar-containing pollen florets than average. You could grow butterfly-friendly zinnias by simply buying and growing butterfly-friendly varieties. ZM...See Morepineresin
