Opis:
There have been several efforts to plant trees in Uganda but the rate of tree planting has remained low perhaps due to coercing farmers to plant the tree species against their preference. In this study, the tree species’ preferences of farmers in Albertine rift are presented. Key informant interviews, focus group interviews and semi-structured household survey questionnaires were used. A sample of 218 households was selected randomly to include both tree farmers and non-tree farmers in Kiryanga Sub County. The descriptive summaries and content analysis were used in data analysis. Results indicate that Eucalyptus spp., Pinus spp., and fruit trees were most preferred. Farmers have different tree species’ preferences due to the benefits obtained from them. Provision of these suitable tree species’ seedlings will highly incentivize and enhance tree planting in Uganda.

Opis:
The results of the study on morphological variation of fruits and seeds of a rare forest tree species Sorbus torminalis (L.) Crantz in Poland are presented and discussed. The ripe fruits were collected from 13 localities widespread within the range of the species. Fruits and seeds were measured according to 13 morphological traits. The biometric data were subjected to multivariate statistical analysis in attempt to define intra and inter populational variation. Most of the fruit and seed traits are significantly correlated and are characterized by moderate level of variation. Traits describing size and shape are higher variable in seeds than in fruits. High level of variation within examined populations was ascertained. The average among population component of variation was only 23.99%. Though the differences between sampled populations are significant, almost no geographical pattern of this differentiation was detected. The biological significance of some of fruit and seed features is discussed in the paper. Examining the collected material a single fruits with 5–6 seeds were found what suggests the presence of three carpels in gynoeceum, a number not previously reported in the species.
