It may be qualified as 'temporally dioecious' in that it produces functionally unisexual male and female inflorescences in an alternating cycle on the same plant, resulting in an allogamous mode of reproduction. The 'sex ratio' of an oil palm stand is influenced by both genetic and environmental factors. In particular, the enhancement of male inflorescence production in response to water stress has been well documented. Scope This paper presents a review of our current understanding of the sex determination process in oil palm and discusses possible insights that can be gained from other species. Although some informative phenological studies have been carried out, nothing is as yet known about the genetic basis of sex determination in oil palm, nor the mechanisms by which this process is regulated. Nevertheless new genomics-based techniques, when combined with field studies and biochemical and molecular cytological-based approaches, should provide a new understanding of the complex processes governing oil palm sex determination in the foreseeable future. Current hypotheses and strategies for future research are discussed. specialized Sex determination oil palm Elaeis guineensis inflorescence monoecious temporal dioecy flowering 076 108 8 : Special Issue : Palm Biology 1529-1537 2011 0305-7364 https://www.documentation.ird.fr/hor/fdi:010054184 10.1093/aob/mcr151 0305-7364 [F B010054184] https://www.documentation.ird.fr/hor/fdi:010054184 https://www.documentation.ird.fr/intranet/publi/2011/12/010054184.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2012-01-10 2017-08-23 fdi:010054184 fre
