Видовые эколого-биохимические особенности нектара медоносных растений

Видовые эколого-биохимические особенности нектара медоносных растений

Abstract

Методом высокоэффективной жидкостной хроматографии исследован состав нектара основных медоносных и лекарственных растений умеренного пояса: клевера ползучего (Trifolium repens L.), ивы белой (Salix alba L.), липы мелколистной (Tilia cordata L.) и донника белого (Melilotus albus L.). Статистически обоснованы видовые биохимические показатели нектара по содержанию водорастворимых витаминов, свободных аминокислот, алифатических карбоновых кислот и фенольных соединений. Нектар травянистых растений клевера ползучего и донника белого отличался от нектара древесных растений липы мелколистной и ивы белой более высоким содержанием аминокислот, витаминов и фенольных соединений. Приведены данные по основным группам насекомых, опыляющих исследованные виды растений. Установлена взаимосвязь состава нектара с систематическим положением растений, а также продемонстрирован коэволюционный аспект между биохимическим составом нектара и пищевыми предпочтениями насекомых-опылителей.

Nectar samples of the main melliferous plants: white clover (Trifolium repens L.), white willow (Salix alba L.), small-leaved lime (Tilia cordata L.) and white melilot (Melilotus albus L.) was studied. Contents of water-soluble vitamins, free amino acids, aliphatic carbonic acids and phenolic compounds was determined using high-performance liquid chromatography (HPLC) methods. Specific biochemical content of melliferous plants nectar was statistically supported. Studied plant species differed in the nectar composition and visited by different insects groups. Nectar of herbal plants differed from nectar of woody plants in higher content of amino acids, vitamins and phenolic compounds. The interrelation of composition of nectar with the systematic provision of plants is established and also showed coevolutionary aspect between biochemical composition of nectar and food preferences of insects pollinators.
