Tissue culture has emerged as an auxiliary technique for improving citric species with the aim of surpassing the difficulties found in applying the conventional methods. This technique has also been used in studies involving mutation inductio with the aim of obtaining solid mutants whn mutagenic agents are used to increase frequency of mutations.  aCitrus  aCitricultura  aCitros - genetica  aCitros - melhoramento  aCitros - tecido - cultivo  aCitros - tecido - cultura  tLaranja, Cordeirópolesgv. 12, n. 2, p. 331-344.
