Abstract:
During the flowering period of 1998, insect pollinators of twovarieties of Hedysarum coronariunaL.(GrimaldiandSparacia)were monitored inanareaofNorthernSardinia(Italy).TheApidaeApis nlellifera L.andthe Anthophoridae Eucera numida Lep. were the mainpollinators.Among the seedyield components, the number of loments per raceme and seeds per loments were 98% and 42% lower, respectively, in the absence of pollinators in Grimaldi. The percentage of flowers setting seedwas about 50% in both varieties,eventhoughthemeannumber of pollinators perflowerwas 1.4 fold higherinGrimaldithan in Sparacia.
