Abstract


As regards the study of in vitro pollinic fertility, the best conditions for germination and elongation of the pollinic tube are obtained at 20 g/l sucrose, 0.62 g/l of boracic. On the whole, foreign varieties (Carotina, Marmande, Makis, Opal, Roma) have a weak indicator of viability as compared to local varieties. Fertility of different flowers analyzed according to their position on the plant, is generally decreasing from bottom to top. These results could explain some cases of failure of fertilization when crossing-over different varieties of tomatoes. The results also show the importance of choice of the flower used when sampling pollen grains.

Abstract: (french)


En ce qui concerne l'étude de la fertilité pollinique in vitro, les meilleures conditions pour la germination et l’élongation du tube pollinique sont réalisées à 20gr/l de saccharose, 0,62 gr/l d’acide borique. Dans l’ensemble, les variétés étrangères (Carotina, Marmande, Makis, Opal, Roma) ont un indicateur de viabilité faible par rapport aux variétés locales. Quant à la fertilité de différentes fleurs analysées suivant leur position sur la plante, elle est généralement décroissante de bas vers le haut. Ces résultats expliqueraient certains échecs de fertilisation lors de croisement entre différentes variétés de tomates et montrent l’importance de choix de la fleur servant pour le prélèvement des grains de pollen.
