Before:
JAR–FCL 1.125 (…)
(c) Night qualification. If the privileges of the licence are to be exercised at night, at least five additional hours flight time ....
The word additional was construed, at least in France (I don't know about other JAR countries), as meaning that the total training had to be 45 + 5 = 50 hours.
Now:
FCL.810 Night rating (...)
(1) If the privileges of an LAPL or a PPL for aeroplanes, TMGs or airships are to be exercised in VFR conditions at night, applicants shall have completed a training course at an ATO.
There are 45 hours in the PPL course, I don't think that anything forbids you to train your student at night for part (maybe all?) of the 45 hours.
Nevertheless, I understand a training course as meaning another course than the PPL course, from which I conclude that the total training should be 45 + 5 = 50 hours.
