Dr Wei's thesis comprises 12 independently published studies. This was record in the faculty history when the thesis was presented, the second largest thesis comprised 7 studies and faculty average was 4.8.

Ten of the studies (thus all initially heading for that) are now published in refereed acknowledged scientific journals, each study in a separate journal and the list includes the most relevant journals for this type of articles.

Dr Wei came to Umeċ for a Ms study and started the field work at arrival to Umeċ, but the results were not included in the thesis. It was about epigenic effects, when he arrived it was assumed he should get a training one and half year as a breeder and I saw experience from field work as important and I was interested of the results.  It was first later I realised that this was a suitable collaborator for breeding theory. The paper is Lindgren D & Wei R-P 1994. Effects of maternal environment on mortality and growth in young Pinus sylvestris field trials. Tree Physiology 14:323-327. By this misjudgement I decreased the number of studies in thesis by one.

Duration of PhD studies: Nov. 1991 – Jul. 1995 = 45 months. However Wei arrived to Umeċ Oct 1990 and registered into a PhD programme first a year later.
