Plant sexual systems correlated with morphological traits: Reflecting reproductive strategies of alpine plants

---

Plant sexual systems can be affected by various environmental factors, and thus show a range of
morphological differences. The associations between plant sexual systems and morphology are unique, for example,
the subnival belt of the Hengduan Mountains has harsh climatic conditions, but hosts remarkable biodiversity.
However, these associations have received surprisingly little attention. We analyzed the associations in this region,
and compared the pattern of sexual systems with that of other floras, and we also reviewed the breeding system of 36
alpine species. Information on plant sexual systems and these traits were mainly based on published information,
herbarium collections, and field observations. The results showed that there was a high proportion of hermaphroditic
species and a low proportion of dioecious and monoecious species. Hermaphroditism was strongly associated
with showy floral displays, specialist entomophily, and perennial forbs. Dioecy was strongly associated with
inconspicuous, pale‐colored flowers, anemophily, and shrubs, whereas monoecy was strongly associated with
inconspicuous, pale‐colored flowers, generalist entomophily, and perennial grasses. Although no association was
found between sexual systems and fruit type, plants with dry fruits (98.1%) were predominant in our study region.
With respect to the plant breeding systems in the alpine region of southwest China, we predicted that pollination
service might be particularly low; most of the plants lacked enough outcrossing pollinators. Our data revealed that
97.1% of the hermaphroditic species were self‐compatible, and 88.2% of them showed autonomous or facilitated
selfing. The plant sexual systems identified might serve to optimize the probability of pollination and thus ensure
reproductive success.

Key words alpine subnival belt, floral display, fruit types, Hengduan Mountains, pollination syndrome, sexual
systems.
