A morphological study of three Asian populations of pink salmon of the Ola, Bolshaya and Zhupanov rivers of adjacent even generations was carried out. For a quantitative description of the external appearance of pink salmon, a scheme of 17 measurements proposed by M.K. Glubokovsky [3] was used. On average, lower values of morphological diversity are characteristic of head measurements and fin heights, while indicators of body length and height have high indicators of morphological diversity. The hierarchical method of decomposition of morphological diversity makes it possible to find out the proportions of intrapopulation and interpopulation variability included in the total value of morphological diversity of each measurement. For females, the shares of morphological diversity averaged over all dimensions are as follows: sample — 48%, intra-annual — 19% and interpopulation — 33% share In males sample — 47%, intra-annual — 17% and interpopulation — 36% share. Thus, almost half of the total value of morphological diversity is determined by differences in morphological measurements between individuals within the sample, interpopulation differences make up one third of the total value, and the interannual share in the indicator of morphological differences is quite small. The rather high interpopulation proportion of morphological diversity indicates the possibility of using morphological measurements to distinguish populations from different parts of the range.

We have studied chloroplast DNA variation within six individual trees of a Pinusbanksiana–P. contorta sympatric region. In each of four trees, chloroplast DNA variation occurred in needle samples obtained from different parts of the crown. It is unclear whether this within-individual variation is due to somatic mutation or to occasional biparental chloroplast DNA inheritance. However, the data provide evidence that variation within individuals may be an important source of genetic variability in sympatric regions of forest trees.

The maize transposable element Activator (Ac) has been shown to be active in a number of dicots, including arabidopsis [Arabidopsis thaliana (L.) Heynh.], tobacco (Nicotiana tabacum L.), tomato (Lycopersicon esculentum Mill.), potato (Solanum tuberosum L.), and aspen (Populus tremuloides Michx.). However, no information is available on somatic transposition in any plant during several years of growth and development. It is not known how transposition affects genetic variability among vegetative parts that have developed during a long period of growth. In order to explore the possibility of using somatic Ac transposition for gene tagging and mutagenesis in fruit trees, a derivative of the maize Ac transposable element was introduced into `Duncan' grapefruit (Citrus paradisi Macf.) by Agrobacterium tumefaciens (Smith & Towns.) Conn.-mediated stable transformation. Genetically identical 4-year-old sibling trees were established by grafting one of the transformants on Troyer citrange [Citrus sinensis (L.) Osbec. × Poncirus trifoliate (L.) Ras.] rootstocks. We demonstrated that the Ac element was active upon transformation in citrus (Citrus L.) trees and that transposition can create genetic variability among tree siblings and among leaves collected from different parts of the same tree. Ac was still active among propagated plants 4 years after transformation, clearly indicating that it is capable of maintaining itself in citrus trees for a long period of time. The observation of different integration patterns in different parts of the same tree and within tree siblings originating from the same transformant suggests that an Ac-based mutagenesis system could be very useful in creating somatic mutations in citrus trees.
