Nectaries are located on <strong>the</strong> base <strong>of</strong> <strong>the</strong> leaf (ref.: Handbook <strong>of</strong> peach and nectarine<br />
varieties – Per<strong>for</strong>mance in <strong>the</strong> Sou<strong>the</strong>astern United States and index <strong>of</strong> names, W. R. Okie -<br />
United State Department <strong>of</strong> Agriculture - Agriculture Research Service - Agriculture<br />
Handbook Number 1714 – May 1998: page 12). This character, both on petiole and leaf, is<br />
fluctuant during <strong>the</strong> season; So, <strong>the</strong> most important is that <strong>the</strong> shape and <strong>the</strong> number <strong>of</strong> glands,<br />
as well as <strong>the</strong> area (petiole/leaf), must be determined on adult, full-sized leaves <strong>of</strong> mature<br />
trees (on <strong>the</strong> young leaves in growth, <strong>the</strong>y are more or less well constituted and on too old<br />
leaves, <strong>the</strong>y dry out and fall), if possible in be<strong>for</strong>e harvest, during a short period <strong>of</strong> one or two<br />
weeks <strong>for</strong> a set <strong>of</strong> varieties in experimentation / characterization.<br />
