andros88 Posted March 8, 2019 Share Posted March 8, 2019 Hi all - has anyone here had success with germinating A. burkittii? They seem much more challenging than other acuminata variants. 2x hot water treatment 2 weeks apart yielded no results (unlike a. broad or narrow phyllode which usually germinate within a week of hot water treatment). Thanks for any help in advance! Quote Link to comment Share on other sites More sharing options...
ENtiTY Posted March 21, 2019 Share Posted March 21, 2019 Not tried burkittii but I have grown many other acacia. Personally I prefer to sand some of the seed coat away before hot water treatment. Not to much, you only need to break the very outer gloss coating, so you can see a bit of a flat spot. Seeds will swell if the process is successful. Much more reliable than just a hot water soak. 1 Quote Link to comment Share on other sites More sharing options...

Thanks for any help in advance! I germinated many acacias but burkitti doesn't germinate so far. From about 10 seeds nothing happend. Treatment with boiling water and swelling worked before with all other Acacias but the burkitti seeds seem to need something different or I have bad or old seeds.

ENtiTY Posted March 21, 2019 Share Posted March 21, 2019 Pathogens perhaps. If using boiling water treatment try sowing in an inert medium like coarse sharp sand that has been nuked and let cool to room temp. Otherwise once the seeds are soft after treatment you can pull one apart carefully to see if it is healthy or a shrivelled soggy mush inside. If its mush your seeds are junk. If healthy then its probably a pathogen in your soil mix. 2 Quote Link to comment Share on other sites More sharing options...
andros88 Posted March 24, 2019 Author Share Posted March 24, 2019 Hi all - thanks for your responses. I planted 40 seeds on the 5th of March after hot water treatment. After no germination for a couple of weeks (this is the 2nd time I tried germinating burkitii) I did a range of things: 1. Dug up some seeds + scarified outer shell with knife or sand paper & placed again in warm water. Then placed back into soil. 2. Left all seeds to dry out in the sun (soil was totally dry). 3. Re-wetted the seeds. Seeds from the both the scarified & non-scarified groups have now germinated (5 total). It seems they respond to dry & wet cycles. Have found germinating burkittiis to be more difficult than other legume-type (Fabaceae family) plants (have germinated a. confusa, a. acuminata narrow, typical, bundleflower, mimosa hostilis with just hot water treatment with higher germination rates). 1 Quote Link to comment Share on other sites More sharing options...
infi Posted March 24, 2019 Share Posted March 24, 2019 Maybe Burkitti needs some extra treatment. Will try to dry mine out a bit. I will also try a Gibberellic acid treatment. Quote Link to comment Share on other sites More sharing options...
sagiXsagi Posted October 10, 2019 Share Posted October 10, 2019 sanding/filing the seeds a must for me. Snu mentions burkittii as a ssp of acuminata btw Quote Link to comment Share on other sites More sharing options...
ENtiTY Posted October 13, 2019 Share Posted October 13, 2019 Perhaps they would respond to smoke treatment. Many native species require it to break dormancy. Quote Link to comment Share on other sites More sharing options...
