The advantage of low leafing intensity under water limitation: An illustrative study of <i>Populus euphratica</i> in hyper-arid climates.

Because stem mass varied across habitats more pronouncedly than leaf number did ( Table 1 ), the reduction in leafing intensity can be mainly attributed to larger stem mass under higher climatic aridity, even though the latter trend was just marginally significant ( Fig. 1 d).
