摘要: In this investigation, two previously reported precipitation δ2H isoscapes for New Zealand were used to develop a isoscape blackberry (Rubus sp.) leaf. These calibrated using the measured values of 120 authentic leaf samples collected from across country. A regression model based on environmental variables available was also determined predict leaves without initially modelling values. The three models compared their accuracy and precision when assigning 10 geographic location One similar in assignment provides an approach determining valid future plant materials.
