Abstract: Blooming characteristics and pollinators of Liriodendron chinense(Chinese tulip tree)and L. tulipifera(tulip tree)in a provenance trial plantation including 17 provenances were investigated based on observations over two years on 6 trees in Jurong City, Jiangsu Province. Results showed a moderate difference for initial anthesis among 6 provenances, but no difference among individuals within a provenance. For the number of flowers during bloom, variationswere also found among species,provenances and individuals.However,no interspecies variations were found for the pollinators and their visiting frequency. Altogether, 14 animal species from the orders Diptera(2), Hymenoptera(6), Coleoptera(4), Leoidoptera(1), and Araneae(1)were observed visiting the flowers of Liriodendron. Of these orders three families, namely Syrphidae(flies)(1)and Formicidae(ants)(2), as well as one species, Apis mellifera(bees), were major visitors. When visiting flowers, different visitors had different behaviors with geitonogamy being observed. Generally, the visiting frequency of the visitors was related to the number of daily flowers blossom, the greater the number of blossoms, the higher the visiting frequency.[Ch, 1fig. 2 tab. 13 ref.]
