Plant stem thickness?

Question

Is there a website where I can find the thickness of a plant stem? Like its diameter. It's for something I plan to do. I've tried googling, wikiing etc and I still can't find the information I need.
I need to know the thickness of the stem of a tomato plant, pepper, eggplant, cucumber, squash, and watermelon.

I need to know the diameter of the thickest stem

Answer 1

may be some breeding institutes can help you. Or you can try to find these phenotypic data by seeking databases as pubmed with keywords like "tomato stem diameter phenotype" and so on. Specially the older ( I mean old!) articles will for sure mention these data and most of them are with free access.
