Abstract

Floral features, the pollination process, the breeding system, and fruiting success are documented in the Andean terrestrial orchid Gomphichis valida. Studies were performed at the Department of Ancash, Peru, at ca. 4250 m a.s.l., from June to November 2022. The breeding system was studied through controlled pollinations in plants excluded from pollinators (bagged). Natural pollination was studied in the field and through photos and videos. The flowers are nectariferous and non-protandrous and present the longest lifespan reported so far for a neotropical terrestrial orchid (53–80 days). This species is pollinator dependent (unable to set fruit and seed without the agency of pollinators) and self-compatible. The observed pollinators belong to three functional groups that appeared successively (in order of appearance): hummingbirds (Chalcostigma stanleyi), bumblebees (Bombus coccineus and Bombus rubicundus), and solitary Halictidae bees (Augochlorella sp.). All recorded pollinators probe the flowers for nectar. The pollinaria adhere to the bee mouthparts and onto the lateral side of the hummingbird bill. Bumblebees were the most frequent and efficient functional group (up to 62.07% of the observed pollination events), followed by Halictidae (31.03%) and hummingbirds (6.90%). Natural fruiting success is high (66.66%–94.49%). Such high natural fruiting success is unexpected at high altitudes, but it is likely explained by a combination of factors, including the long floral lifespan, nectar secretion, and self-compatibility. This is the first report of hummingbirds as pollinators of Cranichidinae orchids, and G. valida is, to the best of our knowledge, a neotropical orchidoid orchid with the most generalist pollination biology recorded so far.

Gomphichis valida Rchb. f. (Orchidaceae: Orchidoideae, Cranichidinae) 的生殖生物学:安第斯高纬度地区长寿花陆生兰花的通性授粉
研究记录了安第斯陆生兰花 Gomphichis valida 的花朵特征、授粉过程、繁殖系统和结果成功率。研究在秘鲁安卡什省约海拔 4250 米处进行。研究于 2022 年 6 月至 11 月在海拔 4250 米的秘鲁安卡什省进行。繁殖系统的研究是通过控制植物授粉(袋装),排除授粉者。自然授粉是在野外通过照片和视频进行研究的。该花为蜜源花,无雌雄异株,是迄今为止所报道的新热带陆生兰花中寿命最长的一种(53-80 天)。该物种依赖授粉者(没有授粉者的帮助就无法结实和播种),并且自交。观察到的授粉者属于三个功能群,它们依次出现(按出现顺序排列):蜂鸟(Chalcostigma stanleyi)、熊蜂(Bombus coccineus 和 Bombus rubicundus)和独居的 Halictidae 蜜蜂(Augochlorella sp.)。所有记录在案的传粉昆虫都会探头采花蜜。花粉块粘附在蜜蜂口器和蜂鸟喙的侧面。熊蜂是最常见和最有效的功能群(占观察到的授粉事件的 62.07%),其次是半翅目(31.03%)和蜂鸟(6.90%)。自然结果成功率很高(66.66%-94.49%)。在高海拔地区,如此高的自然结果成功率是出乎意料的,但这可能是由多种因素共同作用的结果,包括花的寿命长、分泌花蜜和自相容性。这是蜂鸟作为蔓生兰科兰花授粉媒介的首次报道,据我们所知,G. valida是迄今为止记录的新热带兰科兰花中具有最普遍授粉生物学特性的兰花。

期刊介绍: Plant Species Biology is published four times a year by The Society for the Study of Species Biology. Plant Species Biology publishes research manuscripts in the fields of population biology, pollination biology, evolutionary ecology, biosystematics, co-evolution, and any other related fields in biology. In addition to full length papers, the journal also includes short research papers as notes and comments. Invited articles may be accepted or occasion at the request of the Editorial Board. Manuscripts should contain new results of empirical and/or theoretical investigations concerning facts, processes, mechanisms or concepts of evolutionary as well as biological phenomena. Papers that are purely descriptive are not suitable for this journal. Notes & comments of the following contents will not be accepted for publication: Development of DNA markers. The journal is introducing ''Life history monographs of Japanese plant species''. The journal is dedicated to minimizing the time between submission, review and publication and to providing a high quality forum for original research in Plant Species Biology.
