The authors attempt to determine the optimal conditions for maintaining long term viability of date palm pollen using a special method of freeze-drying. They have undertaken a systematic study of the viability over time of a sample of the same pollen stored and conserved under different conditions (freeze-drying, temperature, gaseous atmosphere and storage time). The results are thoroughly analysed by means of different approaches of multiparametric modelisation. These numerical treatments permit us to: Les auteurs ont determine, par une methode particuliere de lyophilisation, les conditions optimales permettant le maintien de la viabilite du pollen du palmier dattier (Phoenix dactylifera) a long terme. Une etude systematique a ete realisee sur des lots provenant d'un meme echantillon de pollen conserve et stocke selon differentes conditions: (lyophilisation, temperature, atmosphere gazeuse et en fonction du temps de stockage). Ils ont cherche a analyser de maniere approfondie les resultats obtenus au moyen de plusieurs approches de modelisation multiparametrique. Ces traitements numeriques ont permis: 1. demonstrate that such a phenomenon submits to the usual laws and can be modelled 2. propose a general approach for the study of the ageing of pollen with time and with respect to different conservation and storage conditions. 1. de demontrer qu'un tel phenomene obeit globalement a des lois statistiques simples, et qu'il est de ce fait modelisable 2. de proposer une approche plus generale du vieillissement des grains de pollen en fonction du temps et des conditions de conservation et de stockage. |
