Aranjuelo et al. (2013)

Photosynthesis of fully-expanded apical leaves of plants grown one to each of several 2.5-L pots filled with a 3:2 (v/v) mix of vermiculite-perlite that were drip-irrigated with N-free nutrient solution for N2-fixing plants that were allowed to grow under these conditions for a period of 4 weeks

Photosynthesis of fully-expanded apical leaves of plants grown one to each of several 2.5-L pots filled with a 3:2 (v/v) mix of vermiculite-perlite that were drip-irrigated with 10 mM KNO3 for nitrate-fed plants that were allowed to grow under these conditions for a period of 4 weeks

Aranjuelo et al. (2013)

Photosynthesis of the total dry matter of well-watered plants grown for four weeks, one to each 2.5-L plastic pot filled with a 3/2 mixture of vermiculite/perlite, in controlled-environment chambers where they were fertilized with N-free nutrient solution for N2-fixing plants
