Abstract

This study explores and reports on the gain brought to the morphogenetic aptitude of female date palm inflorescences through in vitro hermaphrodism induction It investigates the main factors involved in the process of sex modification through hormonal induction such as the floral developmental stage and hormone combination and concentration It demonstrates that the vestigial stamens staminodes of female date palm flowers display a new and high capacity to proliferate under particular in vitro conditions without blocking carpel’s development leading to morphologically typical hermaphrodite flowers This de novo activation of repressed stamens was found to occur rapidly The isolated pollen mother cells appear in the obtained anther’s locules and undergo an ordinary microsporogenesis process The data show that hermaphrodism induction depended heavily on both the growth regulators applied and the flower’s developmental stage They also confirm the early theory that suggests that dioecious plants come from a hermaphrodite ancestor Such hermaphrodism control can provide new prospects and opportunities for the investigation of the in vitro selffertilization process It can also be useful in improving the understanding of the genetic mechanism involved in sex organ development in date palmThis work was supported by the Ministry of Higher Education Scientific Research and Technology in Tunisia and the International Atomic Energy Agency under TC Project RAF/5/049 The authors would like to thank the staff of the Regional Centre of Oasian Agriculture Research in Deguache south of Tunisia for their help in collecting the inflorescences They wish also to extend their gratitude to Mr Anouar Smaoui from the English Department at the Sfax Faculty of Science for his valuable editing and careful reviewing of the manuscript of the current study
