The objective of this study was to describe the dispersion, color, size and morphological characteristics of fruits and seeds of Lupinus albescens, as well as pre-germinative treatments, aspects of luminosity and seed conservation. Above twenty populations were collected in São Francisco de Assis/RS and Alegrete/RS, pre-germinative treatments (seven pre-germinative methods, scarification times and temperatures) were analyzed; photoblastic test (seeds scarified between sandpapers, submitted to 25ºC); imbibition curve (control and scarification treatments between sandpapers); seeds conservation (cold room in plastic bag and natural environment in paper bag). Evaluations: description of fruits, seeds and viability analysis, using a completely randomized design. The results showed dispersion by autocoria, brown coloration of fruits and seeds and some striped seeds. Superior pre-germinative treatment was between sandpapers, for 40 seconds and under 25ºC. Seeds are classified as neutral photoblasts and without dormancy. Natural environment and paper bag were suitable for storage.
