Hi Chandrabala
Hi Chandrabala These links may be of help. http://www.fs.fed.us/psw/publications/documents/psw_gtr214/psw_gtr214_075-081_uribe.pdf http://www.benthamscience.com/open/toccmj/articles/V001/54TOCCMJ.pdf Note: in the first paper the authors use Sigma Plot for estimating the parameters. For the 2nd paper look at the Jonson reference [2] for help. Do a google search looking for sigmoidal equation model fitting etc. You mention excel take a look at the mathematical Excel SOLVER. Hope this is of help Ling Ling Huang Sacramento City College --- On Wed, 7/18/12, Chandrabala <[email protected]> wrote: From: Chandrabala <[email protected]> Subject: Re: [ECOLOG-L] P-V curves To: [email protected] Date: Wednesday, July 18, 2012, 9:59 PM thank you so much.. i had earlier seen the link " http://prometheuswiki.publish.csiro.au/tiki-index.php?page=Leaf%20pressure-volume%20curve%20parameters " and its very helpful, i am struggling with the curve fitting and linear regression of the graph as i am not good at making graphs and statistical tests and excel. i am a begginer.. it would be very helpful if i can get any protocol for developing the graph after i had the data for P-V curve thanks Chandrabala On Thu, Jul 19, 2012 at 7:45 AM, ling huang <[email protected]> wrote: > Journal of Experimental Botany, Vol. 49, No. 328, pp. 1845–1854
