How long does it take for Burmese grape seeds to sprout?

[sildanani]

I bought fresh seeds from a Thai vendor mid-June, and they haven't sprouted yet. How long does it take? Or are they still good?

I bought seeds of burmese grape, salak, and calabao. They came in sealed plastic packages as if they were ages old. None of them sprouted and I planted them last summer, not wanting to give up hope. I don't think they were fresh at all is my problem, don't know about how fresh your seeds were when planted.

Fresh Baccaurea seeds start to germinate within a few weeks. They are recalcitrant, so old seeds are hard to germinate.

They can sprout with a couple of weeks to a couple of months.Genuine Burmese grape seeds are purplish.Clean seeds have shorter viability than those dried with mucous coat on. Over drying can render them unviable and shorten their life also.
