The δ</span><sup>13</sup><span>C and δ</span><sup>15</sup><span>N of pulp and the δ</span><sup>18</sup><span>O of juice can be considered effective tools for identifying the different geographical origin of fruit. There was a significant effect of crop cover on juice δ</span><sup>18</sup><span>O, and fertilisation practices on pulp δ</span><sup>15</sup><span>N.</span></span></p>
