Summary
Analysis of the cumulative data on the 24 lines produced by conditioning treatments in variety 16 of Nicotiana rustica shows that for the mature plant characteristics exemplified by final plant height, the lines fall into three groups, large, intermediate and small. In this respect they are in broad qualitative agreement with the three genotrophs induced in flax, although it is not yet certain which of the three, if any, in N. rustica corresponds to the original plastic genotroph. This classification, however, while of practical utility breaks down as more characters, particularly juvenile and developmental, are considered.
