We present new modes of convergences for bounded sequences in the space L¹_X(μ) of Bochner integrable functions over a complete probability space (Ω, F, μ) with values in Banach space X via the convergence of its truncated subsequences as well as we give several characterizations of weak compactness and conditionally weak compactness in L¹_X(μ). New results involving subsets in L¹_X(μ) which are closed in measure are obtained and also the characterizations of the Banach space X in terms of these modes of convergence.
