TSW ISTA RULES

[ID00001802fde1e704db4880eb150437c7ed58c5d7795d1aaMember Silvia Curnis]

Hello, can anyone help me?
I have a question about TSW method in ISTA rules. We are not an ISTA laboratory, but we follow their rules.
We have more and more Thousand-seed weight analysis and sometimes we have some doubts.
We must do this test on pure seeds but, for exemple, if I have double Parsley (schizocarp is a pure seed according to the PSD) I have to count 1 or 2 seeds? And in case of Coriander? This one is often in his schizocarp form…
I think I have to refer to PSD and count a parsley schizocarp as 1 pure seed, the same with coriander…. And, raher, with Malva sp. only the mericarp is a pure seed. Am I wrong?

Thank you very much.

Kind regards,
Silvia
