Most of the studies suggest these two traits strongly positively correlated. I wish to know studies, if any, where they found a negative or a weak correlation. Also its shown that leaf hydraulic conductance strongly and positively correlated with SPI but weakly with stomatal density and guard cell length. Thanks in advance for any thoughts.

These 3 papers describe stomatal opening and the hydraulic capacity of the soil, roots and stem and the parameters you enquire about:
DOI: 10.1111/j.1399-3054.1991.tb02160.x
Plant, Cell and Environment (2003) 26, 1343–1356
New Phytologist (2005) doi: 10.1111/j.1469-8137.2005.01432.x
I hope that helps!

When humidity in full sun light is a limiting factor in a given mean temperature, for growth of leaf blade, then an evolutionary factor for limiting maximal stomatal conductance and Kleaf would be active. Speculative models are restrict to specific cases. Most scholars tend to support the idea for stomatal index being a proxy for CO2 .
