Kinetical Germination Study of the Chamaerops humilis L. var. argentea Andre (Arecaceae)

摘要

Chamaerops humilis, fairly common species in the Western Mediterranean, fell under the human impact in the region of Tlemcen (West Algeria). This study aims to highlight the characteristics of regeneration by planting Chamaerops humilis L. var. argentea Andre. The laboratory experiments tell us about the latency and germination capacity. This is equal to 58% in the experimental conditions. The post-germination survey shows 3 parts: Cotyledonary Cord (CC), Cotyledonary Ocrea (CO) and Radicle (R), different in shape and in length. The growth kinetics is based on morphometric measures of the early stages of developing post germination, enables the elongation speeds of the 1st components to know growth of this taxon. The cumulative growth of 3 parts ranges between 0.232 and 0.165 cm day-1, an average of 0.204 cm day-1.
