Nutlet production and germination in female and hermaphrodite plants of Thymus albicans Hoffmanns. & Link (Lamiaceae)

Description

Some reproductive aspects are studied in Thymus albicans Hoffmanns. & Link, endemie to SW Iberian Peninsula. Pereentage of herrnaphrodite plants fruit set, nutlet production, seed set, reproductive effieiency and percentage of gerrnination of seeds produced by female and hermaphrodite plants are studied. Percentage of female and herrnaphrodite plants is very variable between populations. Nutlet produetion and reproduetive efficiency are higher in female than in herrnaphrodite plants, and this, together with a slightly advaneed gerrnination of seed produced by females, may inerease female fitness in natural populations.
