In this dissertation, three problems--one in meson physics, one in baryon physics, and one in nuclear physics--are analyzed in the large Nc limit of quantum chromodynamics. It is shown that a Hagedorn spectrum emerges naturally for mesons, i.e. that the number of mesons grows exponentially with mass; a new relation for the electromagnetic form factors of nucleon is derived in the combined large Nc and chiral limit of QCD; Nc scaling of the nucleon-nucleon scattering S-matrix is deduced as well as an exact formula for the nucleon-nucleon cross section in the leading order in 1/Nc expansion is derived.
