The herbaceous vine Tropaeolum pentaphyllum Lam. is a geophyte. The species presents potential use as an ornamental, food and medicinal plant. In this study, we aim to understand the reproductive biology of T.pentaphyllum in Brazilian Mixed Ombrophilous Forest, Southern Brazil. Floral structures, duration of the staminate and pistillate phases, interval between phases, overlapping of phases, breeding system were studied. Nectar volume and sugar concentration were evaluated throughout floral longevity. The floral visitor’s behaviour was observed for four years, 6 am to 8 pm, totalling 100 hours of observation each year. Tropaeolum pentaphyllum is protandrous. The mean floral longevity was of 13.6 days. The duration of the staminate ((overline{x}) = 6.7 days) and pistillate ((overline{x}) = 6.1 days) phases did not differ. However, all flowers produced nectar in the staminate phase while just 23.3% produced in the pistillate phase. Sugar concentration remained constant over the floral longevity. Tropaeolum pentaphyllum presents mixed pollination by hummingbirds, bees and ants. Protandry, floral longevity and nectar production for up to ten days are strategies to obtain pollination and promote cross-pollination in T.pentaphyllum. The overlapping of phases (21.4%) also allows self-fertilization if cross-fertilization does not occur. These strategies can be advantageous to obtain crossbreeding and success in sexual reproduction. The longevity of flowers and standing crop of nectar show real food availability for pollinators.
草本藤本植物Tropaeolum pentaphyllum Lam。是地生植物。该植物具有潜在的观赏、食用和药用价值。在本研究中，我们旨在了解巴西南部混交林中五谷霉的生殖生物学。对其花结构、雄蕊期、雌蕊期、期间间隔、期重叠、育种制度等进行了研究。在整个花寿命期间对花蜜量和糖浓度进行了评估。花游客的行为被观察了四年，从早上6点到晚上8点，每年总共观察100小时。对流层虫是雌雄同体的。平均花寿命为13.6 d。雄蕊期((overline{x}) = 6.7 d)和雌蕊期((overline{x}) = 6.1 d)的持续时间没有差异。然而，所有的花在雄蕊期产生花蜜，而只有23.3% produced in the pistillate phase. Sugar concentration remained constant over the floral longevity. Tropaeolum pentaphyllum presents mixed pollination by hummingbirds, bees and ants. Protandry, floral longevity and nectar production for up to ten days are strategies to obtain pollination and promote cross-pollination in T. pentaphyllum. The overlapping of phases (21.4%) also allows self-fertilization if cross-fertilization does not occur. These strategies can be advantageous to obtain crossbreeding and success in sexual reproduction. The longevity of flowers and standing crop of nectar show real food availability for pollinators.

Hemiparasitic plants can reduce photosynthesis and alter the host plant’s foliar traits. This relationship may be more intense in ecosystems with nutritionally poor soil, such as the campo rupestre, known for its high endemism. This work evaluated the impact of a generalist hemiparasitic species (Struthanthus flexicaulis) on the physiology as well as physical and chemical traits of a native species (Baccharis dracunculifolia) frequently found in the campo rupestre. We planted twenty 60-day-old B. dracunculifolia individuals in a campo rupestre area. Two year after planting, during the 2019 dry season, we evaluated the water potential (Ψw), photosynthetic efficiency (PE), specific leaf area (SLA) and succulence (SU) of parasitized and non-parasitized host plants. These parameters were measured again in the dry season of 2020, when we also measured chlorophyll, nitrogen balance index (NBI) and phenolic content of leaves of the same individuals. Parasitized individuals had a higher Ψw and PE compared to non-parasitized individuals during the most critical period of the day (12:00 pm to 3:00 pm). However, towards the end of the day, parasitized individuals had lower Ψw and PE than non-parasitized ones. There was no effect of parasitism on SLA and SU. Parasitized plants had higher NBI and lower phenolic content than non-parasitized plants. We concluded that S. flexicaulis parasitism interfered in the physiology and chemical leaf traits of B. dracunculifolia. Parasitism, while momentarily increasing the PE and Ψw of parasitized individuals, can cause physiological imbalances, which could negatively affect the development and lead to the death of the host plant over time.
