What about a simple scanner and image analysis software? Dedicated image leaf meter currently exists, like Winfolia (http://www.regentinstruments.com/assets/winfolia_software.html), but freeware image manipulation programs can be considered as the cheapest option!

Hi Felix,

if you do'nt have the need of massive analysis (then, the classical LiCor belt would be the best...), I agree with Francesco.

We use the (quite powerful) free package UTHSCSA ImageTool 3.0 developed in the Department of Dental Diagnostic Science at The University of Texas Health Science Center to analyse the pictures. Have a look at http://compdent.uthscsa.edu/dig/itdesc.html

Best,

Andrea

Hi Francesco,

We considered that option initially, but we will have to invest additionally on a fast and good optical resolution scanner. We were hoping to get a whole-package deal.

Also price tag isn't a limitation, just that we don't want to spend lots of money in delivery fees.

Thanks alot for your contribution!

If you have your leaf in your hand:

1)Pput the leaf on any copy-machine and make a hard copy

2) cutt out the leaf with your cisors from the hard copy

3) Put your "paper leaf on a balance and write down the weight

4) do the same procedure with a paper as calibration area with known area in cm2

5) Now you calculate the cm2 of your leaf.

Do it with hundreds of leaves (with the same calibration unit) and you will see that this is the fastest and cheepest method to get accurate readings.

Good luck

If you want to measure leaf area, I recommend LeafByte. It's a free and open source app for iPhones and iPads. It measures leaf area and herbivory (if you have it) much more quickly than ImageJ and related software. It also automatically saves your data for you in a spreadsheet. Did i mention that it's free?

You can download it in the app store or read more about LeafByte at the website below. You can also check out the FAQ page for ways to measure leaves non destructively and in the field.

Disclaimer-I was involved in making this app, but since its free I make no money from its use.
