“…The maximum quantum yield ranged from 0.007 molÁmol -1 for P. scandens to 0.069 molÁmol -1 for H. helix. This 10-fold variation in maximum quantum yield is consistent with the finding the even within the Araceae family, there are large differences in maximum quantum yield among species (0.0014 to 0.112 molÁmol -1 ) (Giorgioni and Neretti, 2010).…”

“…The light compensation point ranged widely among species, from 8 mmolÁm -2 Ás -1 for H. helix to 78 mmolÁm -2 Ás -1 for F. repens. These light compensation points are generally higher than that reported for the shade-obligate Podophyllum peltatum (11 mmolÁm -2 Ás -1 ), Arisaema triphyllum (5 mmolÁm -2 Ás -1 ), S. racemosa (9 mmolÁm -2 Ás -1 ) (Hull, 2002), and G. undatus (2.8 mmolÁm -2 Ás -1 ) (Burton et al, 2007) as well as those of six interiorscape species in the Araceae family (3.0 to 8.2 mmolÁm -2 Ás -1 ) (Giorgioni and Neretti, 2010). The maximum quantum yield ranged from 0.007 molÁmol -1 for P. scandens to 0.069 molÁmol -1 for H. helix.…”

“…How does it compare with the amount of carbon dioxide exhaled by a single person? The approximate amount of carbon exhaled by a single human in 1 d is %300 g (Giorgioni and Neretti, 2010), whereas the carbon content of 1 L of gasoline is 640 g (EPA, 2011). In comparison, a single Spathiphyllum in a 15-cm pot grown at a PPF of 20 mmolÁm -2 Ás -1 fixed 0.8 g C per day, so it would take %400 plants to offset a single human or 845 plants to offset a gasoline use of 1 LÁd -1 .…”

Interiorscape plants have many documented benefits, but their potential for carbon sequestration is not clear. This study was undertaken to quantify the amount of carbon assimilation under growth chamber conditions designed to mimic the photosynthetic photon flux (PPF) levels and temperatures of typical indoor environments and to quantify the amount of carbon assimilation in situ in a representative interiorscape composed of a variety of plant species and sizes. Quantitative data were obtained in 1) growth chambers with a typical range of PPF levels encountered indoors (≈10, 20, and 30 μmol·m−2·s−1); and 2) in situ conditions in an interiorscape. Under growth chamber conditions, most species exhibited positive dry mass accumulation and carbon sequestration but Sanseveria and Dracaena ‘Janet Craig’ exhibited consistent dry mass loss throughout the 10 weeks under simulated conditions. Carbon content was lower in herbaceous species (e.g., Scindapsus aureus, 38% of dry mass) compared with woody ones (e.g., Ficus benjamina, 43%). PPF-saturated net photosynthetic rates of plants were low, ranging from 3.4 to 7.0 μmol·m−2·s−1, whereas their light compensation points ranged from 8 to 78 μmol·m−2·s−1. In situ, plants exhibited varying dry mass gain, largely dependent on size. In general, a large plant and/or species with a higher amount of woody tissue in their above- or belowground organs (e.g., 4.6 m high arboreal plant) sequestered more carbon than small and/or herbaceous species. This study is the first to provide quantitative data of carbon sequestration in interiorscape environments.

“…Nonetheless, the excess of light can cause greater degradation and consequently, a reduction in the levels of total chlorophyll [14]. This response fulfils the function of the photosynthetic antennae absorbing the required light energy [14] considering that the highly pigmented leaves show higher light absorption efficiency per unit of leaf biomass, which may allow the plant to achieve a better carbon balance under light limitation [16][17][18]. In environments with high solar radiation, the increase of photo-oxidation of chlorophylls depends upon the concentration of carotenoids, which can prevent chlorophylls photo-destruction [14], while in low light environments carotenoids may play a more important role in light absorption and its transfer to chlorophyll.…”

Background: Coleus is a perennial herbaceous foliage plant belongs to the family Lamiaceae with long history of medicinal and food uses. Coleus plant have reputed medicinal uses, which includes anti-aggregate, anticancer, antidepressant, antidiuretic, antiglaucomic, antimetastatic, antispasmodic, bronchodilator, bronchospasmolytic, cardiotonic. Hypothesis: Harsh environmental conditions including irregular temperature, unexpected rains and natural calamities have made the production of ornamental plants difficult. Therefore, coleus plants were cultivated under LED intensities to make its availability possible under harsh environmental conditions. Study site and dates: The study was carried out during Feb-May (summer) 2017 at Horticulture Garden, Sindh

“…Solis-Toapanta et al [16] showed that challenges with plant lighting account for almost 20% of the questions asked in popular indoor gardening online communities. In most residential spaces, the photosynthetic photon flux density (PPFD) indoors is 50% to 99% lower than that measured outdoors [17]. Light is particularly important for crops like tomatoes, which have daily light integral (DLI) requirements of 25 to 30 mol•m −2 •d −1 for optimal commercial production [18,19].…”

Our objective was to characterize the growth, physiological responses, fruit yield, and quality of tomato (Solanum lycopersicum L.) plants grown under different daily light integrals (DLIs) and photoperiods. In experiment I, nine compact tomato cultivars were grown indoors using broadband white light-emitting diode (LED) fixtures. Plants were grown under low (10.4 mol·m−2·d−1) and high (18.4 mol·m−2·d−1) DLIs with 12 and 16 h photoperiods, respectively, and two intermediate DLIs of 13.8 mol·m−2·d−1 with either 12 or 16 h photoperiods. In experiment II, three compact tomato cultivars were grown under the same low DLI with either 8 or 12 h photoperiods, and the same high DLI with either 12 or 16 h photoperiods. Generally, higher DLIs decreased plant growth and increased the fruit yield. Changing the DLI delivery strategy by adjusting the photoperiod and photosynthetic photon flux density (PPFD) did not have major effects on the growth, yield, and fruit quality of the compact tomato plants evaluated in this study, even though net photosynthesis increased under higher PPFDs in experiment II. Although several cultivars were affected by intumescence, only two cultivars showed treatment responses, for which the severity was generally higher in lower PPFDs using the same DLI.
