Description

The mobility of S, Rb, Cl, Mo and Ca is compared on the same thallus of Laminaria digitata, with the translocation of 32P previously pointed out and which is considered as a control. The radioisotopes 35S and 86Rb are mobile and their translocation is orientated like that of 32P; 36Cl, 99Mo and 45Ca appear to be non mobile compared to 32P. The results are discussed as to the metabolism of each ion, in relation with the tissue concentrations and with the ionic exchanges with the medium, P being characterized by a low exsorption (5 to 15%), Ca on the other hand, by an important exsorption (80%)

Abstract (French)

On compare sur le meme pied de Laminaria digitata, les deplacements de S, Rb, Cl, Mo et Ca aux migrations du P deja plusieurs fois mises en evidence et prises comme reference. 35S et 86Rb apparaissent, a l'image du 32P, comme des elements mobiles dont la migration est orientee; 36Cl, 99Mo et 45Ca apparaissent comme non mobiles. Les resultats sont discutes en fonction du metabolisme propre a chaque ion, en relation avec les teneurs intra-tissulaires, ainsi qu'avec les echanges ioniques avec le milieu, P se caracterisant par une exsorption faible (5 a 15%), Ca au contraire par une exsorption importante (80%)
