AB  - <jats:title>ABSTRACT</jats:title><jats:p>Leaf senescence results in the recycling of nutrients, thereby providing resources required for growth and reproduction. In this study, the effect of daylength on leaf senescence in eight different <jats:italic>Arabidopsis thaliana</jats:italic> ecotypes was determined and the relationship between senescence and other morphological and life history traits was analysed. A significant variation in the start and extent of leaf senescence depending on the genetic background and the response to daylength was found. Whereas senescence of early flowering ecotypes was accelerated by long days, no effect of daylength on senescence could be found in late flowering Kas1 plants. Senescence in the different ecotypes was associated with other traits, such as floral transition, the total number of fruits, the total number of leaves and the maximum chlorophyll content. Plants that bolted early also senesced early, produced fewer leaves, accumulated less chlorophyll, but produced more fruits. The present results indicate that senescence may be a key component in the tradeoff between investment in photosynthetic capacity and reproduction. The relationship between senescence and other traits was maintained independent of whether differences in senescence were caused by genetic (ecotype) or environmental (daylength) variation, suggesting that genetic and environmental factors affect these traits through common regulatory pathways.</jats:p>
