Help for seed identification

[ID0000331b5927ef41975d39d76f9ff988d92d3ab9153fa86Member Eduard Pelaez]

Hello Everyone,

At our laboratory came this seed and we couldn’t find a correct identification.

Can you help me to identify it?

Hello Eduard,

This seed reminds me of a caryopsis (fruit) of a grass species, could you give us more information:

– the area of production
– the crop it came from
– the size of the seed

Thank you! Jennifer

Hello,

The area is in Colombia, it was founded in a Urochloa brizantha crop, the size is about 3 or 4 mm.

I think it’s a caryopse of poaceae but don’t know which one.

Thanks for your help

Hi Eduard,

I agree it is likely a grass caryopsis. My thought is pearl millet, Cenchrus americanus (syn: Pennisetum glaucum). The size and shape are similar, but I’m not sure if it is grown in Colombia. There should be a dark spot (the hilum) on one side of the narrow end if it is pearl millet.

What do you think?

Thank you, Jennifer

Hi Jennifer,

Thanks for your help, indeed it has the dark spot you mentioned, I reviwed some literature and in fact there are certain appeareances of Cechrus americanus in Colombia.

Again thanks for your help
