Tên bài báo THE FEATURES OF REPRODUCTIVE ADAPTION OF CARNIVOROUS PLANT Utricularia aurea 
Tóm tắt Carnivorous plant (Utricularia aurea) is a suspended aquatic. Inflorescence erect, glabrous, scales absent, bracts basifixed, broadly ovate to orbicular. Calyx lobes ovate, subequal, apex rounded to subacute; lower lobe often slightly broader than upper lobe. Corolla pale yellow, pubescent or glabrous; lower lip transversely elliptic, base with a prominent 2-lobed swelling, apex rounded to emarginate. Filaments 1- 1.5 mm, curved; another thecae confluent. Ovary ovoid; style evident; stigma lower lip semicircular, upper lip obsolete. Fruit: capsule, ovoid, many seeds. The pollen of Utricularia aurea has one morphological form: heterocolpate (polar view). The diameter of fertile pollen is 32,97 ± 0,20 µm, the diameter of infertile pollen is 28,17 ± 0,20 µm. The percentage of fertile pollen is low (< 50%): 26,92% (in peak flowering) and 23,94% (in rare flowering). The percentage of fertile pollen has a positive and close correlation with the diameter of pollen (R = 0,95). Although this species has two reproductive forms (vegetative and sexual), the efficiency of sexual reproduction isn’t high. Vegetative reproduction is always dominant.
