Modifications of vessel size and of shoot hydraulic conductivity induced by different water availability levels -0.35 MPa, -0.6 MPa and -0.8 MPa, respectively) were investigated in container-grown grapevine plants. Plant water loss, measured as xylem sap flow and as leaf transpiration, was lower in water- stressed plants. Morphometric measurements on xylem showed that vessels of water-stressed plants had lower transectional areas. Shoot hydraulic conductivity shoot specific conductivity (ks) and leaf specific conductivity were lower in water-stressed plants.

Hi Jayant,

I have a lot of researchers asking me about water potential in cotton. I am currently working with some scientists in Australia on a project for the continuous monitoring of water potential in cotton with the PSY1 stem psychrometer:

Thanks for updates.

I am currently working on cotton and identifying traits for drought tolerance. PSY 1 stem psychrometer from ICT for measuring continuous water potential in cotton will be useful.

Hello Mashram,

As far as I can understand, may be you will need some pictures of leaves to analyze veins. In that case I can suggest you to try SigmaScan software, which I have used for LAI calculations from leaf areas in my PhD thesis.

Thanks for updates

This is a good resource: http://prometheuswiki.publish.csiro.au/tiki-index.php?page=Quantifying+leaf+vein+traits

Thanks Kevin for hyperlink about vein density measurement.
