2LAP Posted May 5, 2004 Report Share Posted May 5, 2004 Hello All, I've been reading an article by Allen Lowrie where he suggests that Sarrs and Darlingtonia seed may be stratified using three methods, these being... 1. Refrigerate for 6 to 8 weeks. 2. Freeze seeds in a plastic bag with water for 24 hours. 3. 24 hour soak in gibberellic acid. Has anyone tried methods 2 and 3? What were the results?

Guest Aidan Posted May 5, 2004 Report Share Posted May 5, 2004 I have never tried any of alternative methods of stratification and prefer the 'natural' method. Seed sown November through January in a cold conservatory is now germinating and growing fast. The seedlings will now get a full growing season before next winter.

dennisB Posted May 5, 2004 Report Share Posted May 5, 2004 I agree. I don't find it necessary to stratify seeds in a refridgerator even here in sunny South Devon. I sow in late December in an unheated greenhouse and get near 100% germination (not that I've every counted). I guess if you lived in a warm temperate or sub tropical area, the fridge method would be necessary. Dennis Quote Link to comment Share on other sites More sharing options...
Guest padedeji Posted May 5, 2004 Report Share Posted May 5, 2004 Hi I ordered some Sarracenia seed from A.Lowrie last year and as I ordered some minor seed by mistake that I already grew I soaked in gibberellic acid and it germinated OK There was a article on the listserve last year which stated that you could soak in petrol for around 3 hours and then rinse with water before sowing I have never tried it though Regards Phil Quote Link to comment Share on other sites More sharing options...
Dieter Posted May 6, 2004 Report Share Posted May 6, 2004 We had a regional meeting of the German GFP last sunday in Stuttgart including a guided walk through the CP collection of the Wilhelma. Our guide explained that he sows the Darlingtonia seeds directly after harvesting without any additional treatment. He gets a very good germination rate. His statement: If the seeds are really fresh, there is no treatment required. Best regards, Dieter Quote Link to comment Share on other sites More sharing options...
Guest Ross Posted May 8, 2004 Report Share Posted May 8, 2004 I normally naturally stratify, sowing seed around New Year time. None of my seed has germinated this year and the only thing I can think of is because the winter was so mild (pretty much frost free) here. Guess they will sprout next year, whcih seems a long time away..... Quote Link to comment Share on other sites More sharing options...
antipatic Posted May 8, 2004 Report Share Posted May 8, 2004 i've tried the second method, it work and you finish quickly, but i've much result with the "classic "method. classic method: about 100% germination freezer method: about 40-50% germination bye Piero Quote Link to comment Share on other sites More sharing options...
