Without the .= statement, that should do the trick, assuming your 
@array1
abc abc abc abc abc
abc abc abc2 abc3 abc4 abc5
abc abc abc1 abc2

means 
@array1 = (
  'abc abc abc abc abc',
  'abc abc abc2 abc3 abc4 abc5',
  'abc abc abc1 abc2'
);

If it's not working, you need to be more explicit with us (and yourself?) about what's in your array, for instance, by showing the output of 
use Data::Dumper;
$Data::Dumper::Useqq=1;
print Dumper \@array;
