主　　题：Forest trees Seed germination Plant growth Provenance Cote d’Ivoire 

摘      要：The rapid rate of deforestation in Cote d’Ivoire has led to loss of plant species diversity and also threatens some commercial tree species with *** reforestation and aff orestation has been ***,for some species,the numbers of surviving transplants has ***,it is necessary to develop properly adapted and resilient genotypes that can eff ectively support the programs of forest *** this context we evaluated the eff ects of the provenances of seeds and of various treatments on the germination rates and on plant growth of four commercial trees species(Pycnanthus angolensis,Terminalia superba,Mansonia altissima and Pterygota macrocarpa).We analyzed these parameters for seeds of three provenances(Daloa,Akoupéand Daoukro)of four species and for thirty plants aged 6 months per *** to begin germination and time to reach maximum germination were similar among species,and were not infl uenced by either treatment or *** seeds and those soaked for 24 and 48 h in water at room temperature yielded the highest germination rates,irrespective of species or *** one exception was ***,for which no germination was *** species,some provenances produced higher germination percentages than did *** clear relationship was computed between the germination rate and the morphometric characteristics of the seeds which varied signifi cantly between *** growth and morphological variability also depended greatly on *** factors might be implicated,therefore provenance trials should be undertaken and ***,molecular analysis should be undertaken to confi rm the implications of genetic factors and allow for genetic selection.
