英文摘要

A phenological study is one of the first steps in understanding the function of ecosystems. This is because phenological events reflect the way in which the species exploit the so-called favourable periods in order to gain carbon and to allocate photosynthetic products for growth and reproduction. The objective of the present work was to examine the phenology of reproduction and the above-ground growth of several Cenchrus ciliaris accessions, growing under the arid bioclimate in Tunisia. These accessions collected in the south of Tunisia are: Bou Hedma (P1), Tozeur (P2), Raas Jedir (P3) and Sidi Toui (P4). It was demonstrated that an important phenological variability exists within the different accessions studied. The statistical analysis (correlation and principal component analysis) showed that the accession from Bou Hedma (P1) was the most precocious and vigorous one.
