Some results on heavy- and shower-particle multiplicities produced in interactions of 340-GeV pions in nuclear emulsion are presented and compared with similar results in proton-nucleus interactions at different energies. Values of {l angle}{ital N}{sub {ital g}}{r angle} in {pi}{sup {minus}}{ital A} interactions are found to be less than its value in {ital pA} interactions at similar energies. This is understood in terms of additive quark model. The result on mean normalized multiplicity reveals that the values of {ital R}{sub {ital A}1} are almost constant in the forward direction for all values of {l angle}{nu}({ital N}{sub {ital g}}){r angle} and {ital R}{sub {ital A}1} increases with {l angle}{nu}({ital N}{sub {ital g}}){r angle} in the intervals 1.2{lt}{eta}{le}2.0 and {eta}{le}1.2.
