Abstract

In an outdoor experiment in northern Sweden total length of unfed Utricularia vulgaris plants and plants fed copepods and cladocerans peaked in the middle of August in two consecutive years. In both years, during a three week period in July/August, average length growth of fed plants was about twice that of unfed bladderworts. In both plant categories, turion length and the resulting plant length in the middle of August were positively correlated in both years. Irrespective of turion length, the fed plants grew about 13 cm longer than the unfed ones. Fed plants produced longer turions than did unfed ones. Offspring turion length was positively related to parent turion length.
