TAILIEUCHUNG - Ecological aspects of the floral phenology of the cork-oak (Q suber L): why do annual and biennial biotypes appear

Collection of reports on forestry research is published in the journal International Forestry topics: Ecological aspects of the floral phenology of the cork-oak (Q suber L): why the Annual and Biennial biotypes appear? | 114s Ann Sci For 1993 50 Suppl 1 114s-121s Elsevier INRA Original article Ecological aspects of the floral phenology of the cork-oak O suber L why do annual and biennial biotypes appear JA Elena-Rossello JM de Rio JL Garcia Valdecantos IG Santamaria Departamento Biologia Vegetal Universidad de Salamanca 37008 Salamanca Spain Summary Phonological observations periods of flowering and pollination floral structures etc were made over a 3-year period in natural populations of Q Suber. Ne demonstrated the existence of 2 different types of seed cycles in the cork-oak. The annual biotype requires only 1 season to complete its reproductive cycle e similar to that of the Lepidobalanus group whereas the biennial biotype requires 2 full years similar to Erythrobalanus . The variability observed in the cork-oak during the reproductive cycle and the meaning of the existence of 2 different reproductive strategies in the same species are discussed. cork-oak floral phenology ecological variability I reproductive strategies annual and biennial biotypes I Quercus Resume Phénologie florale du chêne-liège Quercus suber L aspects écologiques des biotypes annuel et biannuel. Les observations phénologiques époque de floraison et pollinisation structures florales etc effectuees pendant 3 ans dans des populations naturelles de Q suber ont montré une grande diversite morphologique et de comportement entre populations mais aussi à I in-térieur de chaque population. Le chêne-liège présente 2 differents types de cycle reproductif biotype-annuel qui a besoin d une seule saison pour completer la maturation de ses glands et le biotype-biannuel qui a besoin de 2 ans. La variabilité phénologique observée Chez le chêne-liège ainsi que 1 existence de 2 strategies reproductives si differentes à 1 intérieur d une même espèce sont discutées dans ce travail. chêne-liège phénologie florale strategies reproductives variabilité écologique biotypes annuel et biannuel Quercus Present address Servicio de .
