“…In addition, in the natural environment, the lantana wild cultivar produces more flowers in full sun than grown in shaded environments with low LI. It has been reported that wild cultivars showed a direct correlation between LI and flowering (MUTHAHARA et al, 2018;GOYAL & SHARMA, 2019). In the present study, the LIs studied (W90 and W135) are considered low when compared to a natural light environment, even in shade.…”

“…This species has a great diversity of colors, is rustic in cultivation, and can be pruned if necessary. Furthermore, it responds well to variations in LI (MUTHAHARA et al, 2018;GOYAL & SHARMA, 2019). Thus, the present study evaluated, under a light-restrict environment, the effect of two different LIs of a non-decorative light lamp on growing Lantana camara 'splendens' in ALW.…”

The time spent by urban residents indoors has been increasing annually, thus, prioritizing the enhancement of indoor spaces into green spaces to improve the quality of life. Even with limited environmental conditions indoors, an active living wall and LED light techniques have enabled us to explore indoor green environments. In the present study, the yellow/orange-colored flowers invasive ornamental species,Lantana camara‘splendens’, was cultivated in 4.0 m2 of the active living wall under a non-decorative LED lamp, adjusted to optimize performance in the coverage area. This study evaluated the development of lantana in the active living wall under different light intensities (135 watts and 90 watts) in a room with light restriction. Parameters such as plant height, flowering, SPAD chlorophyll content, and vegetative cover were analyzed. The results indicated that Lantana camara ‘splendens’ is suitable for use in active living walls and blooms at a low light intensity when the light is uniformly applied.

“…Although the assimilation rate of many invasive plants is higher than those reported for Chromolaena , several studies suggest that invasiveness cannot be predicted by the light‐saturated photosynthetic rate alone (Smith & Knapp, 2001). The lower photosynthetic rate at high irradiance in Chromolaena , is possibly related to its lower g (Quan et al, 2015), as well as to other plant traits such as number of branches, total leaf area, and SLA (Goyal & Sharma, 2018; Saito et al, 2012; te Beest et al, 2015), as observed in other species. Some invasive species exhibit similar or even lower light saturated photosynthetic rates and lower growth rates than indigenous species because of higher investment in roots.…”

“…Several studies suggested that changes in plant architecture are adaptations for light harvesting in invasive plants (Charles‐Dominique et al, 2012). Shade individuals are taller with higher SLA, which is indicative of larger assimilatory structures for efficient light interception in comparison to sun plants (Goyal & Sharma, 2018; Saito et al, 2012).…”

“…Despite the worldwide spread of Chromolaena (te Beest et al, 2015; Zhang et al, 2009), little is known of its photosynthetic characteristics and overall performance under field conditions (Liu et al, 2017; Quan et al, 2015). Invasive plants can be successful by maximising photosynthesis via morphological and physiological strategies that increase light capture and utilisation (Goyal & Sharma, 2018; Saito et al, 2012). Efficiency of light capture and use influences both vegetative and reproductive growth (Feng et al, 2007) and ultimately invasive success.…”

In this study, we tested the hypothesis that photosynthetic characteristics contributed to the success and spread of the invasive, C 3 perennial weed, Chromolaena odorata (L.) R. M. King & H. Rob. Measurements of gas exchange, chlorophyll fluorescence and water relations parameters were taken in summer and winter, as well as in sun and shade plants. Typically, diurnal CO 2 exchange increased from dawn to a mid-morning maximum between 10:00 h and 11:00 h, and thereafter decreased gradually for the rest of the day. Light response curves indicated saturation of CO 2 uptake and electron transport rate (ETR) through Photosystem II (PSII) at a photosynthetic photon flux density (PPFD) ≥1800 μmol m −2 s −1 . Maximal CO 2 exchange was 15.64 ± 0.87 (±SE) in summer and 13.15 ± 0.26 μmol m −2 s −1 in winter. Leaf conductance (g), CO 2 uptake (A) and transpiration (E) followed trends similar to those for PPFD. Leaf water potential (Ψ) and water use efficiency (WUE) declined from the predawn maximum values to a minimum at midday and thereafter recovered at dusk. Diurnal trends in actual quantum yield (Φ PSII ) and maximum quantum yield (F v /F m ) decreased from dawn to a minimum at midday, followed by complete recovery at dusk. The relationship between A and g, and A and ETR was linear. Trends in A, Φ PSII and ETR through PSII were tightly coupled to those of incident PPFD. Efficient light utilisation is achieved through modifying plastic traits such as leaf size, specific leaf area and chlorophyll content. Chromolaena is a facultative shade-tolerant weed that exhibits superior light utilisation to maximise carbon gain, while efficient photoprotective mechanisms minimise photoinhibition and photodamage to the photosystems. These adaptive architectural and physiological strategies may probably confer competitive advantage over other species.
