Experimental processes of hybridization in the Laminariales of French coasts.
1983
Cosson, J | Gayral, P
The research has shown that interspecific and intergeneric hybridization is possible in the Laminariales with variable rates according to the species used; these rates were determined precisely only following preliminary study where the rate of parthenogenetic development was evaluated for each particular species. Besides, the results obtained concerning the ecophysiology of the Laminariales and especially the effect of temperature and light on the fertility of the gametophytes, prompt to undertake experimental cultures of the hybrids in order to obtain algae with qualities superior to those of the parents, particularly regarding alginic acid content and growth. The experiments carried out in 1983 concern together the rearing ashore of isolated gametophytes belonging to different species of Laminariales, the realization of crossings in order to obtain hybrid sporophytes, and their transfer into the sea on ropes or nets.
