“…Viola collina under different light conditions displayed plasticity in reproductive growth, especially in the production of flowers. Unlike many plant species which produce only one type of flower, V. collina produce two different (Schemske 1978;Waller 1979), conditions of high light availability generally promote production of chasmogamous flowers (Schemske 1978;Yang and Kim 2019;Yang and Kim 2020). Cleistogamous flowers which are less costly to produce would appear under low light availability conditions.…”

Background: Mixed breeding herb Viola collina Besser, which produces both chasmogamous and cleistogamous flower, has limited habitats under closed canopy and short and early flowering timing, making it relatively more vulnerable to climate change. To better understand the effect of light and nutrient on the flower formation and vegetative growth of V. collina, a mesocosm experiment was conducted. Two-by-two factorial treatments of two light conditions (100% and 60% of natural light) and two fertilizer treatment conditions (fertilized and not fertilized) were applied in the mesocosm experiment. Results:The number of flowers, including chamogamous and cleistogamous flowers, was highest (5.65/pot) under 60% light and fertilized condition and lowest (1.41/pot) under 100% light and not-fertilized condition. However, above ground vegetative growth was highest (2.89 g/pot) under 100% light and fertilized condition and lowest (2.38 g/ pot) under 60% light and not-fertilized condition. Above ground biomass to belowground biomass ratio was highest (1.50) under 60% light and fertilized condition and lowest (1.26) under 100% light and fertilized condition. Conclusions: This study showed that high light and nutrient are responsible for the vegetative growth , though the effect of fertilizer was reduced due to allocation and retainment of nutrients. In addition, the low light is necessary to make flowers, especially chasmogamous flowers.

“…Furthermore, P. chinense is mostly distributed in locations with high light but can also inhabit small gaps formed by the less dense canopy of larger plants in low light (Yang & Kim ). Similarly, under favourable nutrient and water content conditions, both rhizomes and seeds of P. chinense play important roles in expanding established populations (Yang & Kim ). This might be due to its specific realized niche and the reproductive features of P. chinense , with many seeds and small rhizomes (Yang & Kim ).…”

Shade avoidance is expected to be favoured under moderate light. However, in previous studies, shade avoidance was highest in the deepest shade, despite the fact that the plants incur the costs of shade avoidance without the benefits of being exposed to increased light.• We performed shading experiments under different light intensities to understand: (i) how shade avoidance traits of Penthorum chinense could peak in moderate light, and (ii) if there was a trade-off between plant height and allocation of seeds along the light gradients.• Penthorum chinense increased shade avoidance traits with the decrease in light amount, as found in previously studied species. There was a trade-off between height and production of more seeds. The reproductive strategy of P. chinense was to increase seed mass fraction under low light more than under moderate light. This species might be able to expand established populations by both rhizomes and seeds under low light environments.

“…Studies into how population structure and size are related to different environmental and geographic factors can provide valuable information about the ecological needs and life history strategies of species [ [1] , [2] , [3] ]. The International Panel on Climate Change (IPCC) predicted that temperatures will increase by 1–3.7 °C by 2100 [ 4 ].…”
