Tausch» Résumé : In this study we summarize the results of a five-years period concerning seed traits examinations on Iris pumila, Adonis vernalis, Primula veris and Alkanna tinctoria, with special attention to seed dimensions, seed mass and other traits concerning plant fitness, to their variability and the relationship among them. We found tight correlation between seed weight and seed dimensions in Adonis and Primula, at the same time no correlation exists among the same characters in Alkanna tinctoria. Consequently, the seed weight and seed dimensions can be used as synonyms in the form of "seed size" only after preliminary detection of correlations among them. The variability of seed traits is higher in natural categories (individuals, morphs) than in seed mass categories as speculative groups. When we need homogeneous plant stand (e.g. for an introduction experiment) it is suggested to use seeds pre-selected in this way. For ex situ conservation, where the central goal is to maintain the genetic variability, seeds originated from different individuals are preferred.

[CBNPMP-Thèmes] MalherbologieRésumé : Annual weeds have to produce seeds each year to maintain their populations. These seeds fall on the soil surface. Seeds exposed to light during their moistening (i.e. caused by rain) better germinate than seeds in the darkness (i.e. buried). However, rare studies quantified the unique and combined effects of light, moisture and burial depth on the germination process. We investigated, in a greenhouse experiment in 2014, the impact of seed moisture (Moistened vs. Dried), light during moistening (Darkness vs. Light) and burial depth (Buried vs. Surface) on germination of 12 annual weed species contrasted on their seed traits and germination periods (Alopecurus myosuroides Huds., Amaranthus retroflexus L., Avena fatua L., Bromus sterilis L., Capsella bursapastoris (L.) Medik., Cyanus segetum L., Chenopodium album L., Geranium dissectum L., Poa annua L., Sonchus asper (L.) Hill, Veronica persica Poir., Vulpia myuros (L.) C.C.GME L.). Six modalities were tested (with 5 replicates): MDS (moistened seeds in darkness and then placed on the soil surface), MLS (moistened in light and placed on the surface), DLS (dried in light and placed on the surface), MDB (moistened in darkness and then 0.5 cm-buried), MLB (moistened in light and 0.5 cm-buried), DLB (dried in light and 0.5 cm-buried). Datasets were analysed with generalized linear model (GLM, binomial distribution).
