  Title Influence of lunar cycles on growth of Ashwagandha (Withania somnifera [L.] Dunal) Type Journal Article
  Year 2015 Publication Ayu Abbreviated Journal Ayu  
  Volume 36 Issue 3 Pages 258-264  
  Keywords (down) Plants; Moonlight  
  Abstract INTRODUCTION: Ayurvedic classics have advocated to collect the medicinal plants according to part used and seasons in order to get desired pharmacological action and therapeutic benefits. The logic behind this principle is being validated by recent researches. AIM: To analyze the influence of lunar cycles on growth of Ashwagandha in Shishira and Greeshma Ritu (winter and summer season). MATERIALS AND METHODS: Fourteen small crops of Ashwagandha of average size 10 cm were collected on October 7, 2013, from institute campus and then replantation was done at Charaka Herbal Garden, Gujarat Ayurved University, Jamnagar in an area of 60 cm x 60 cm (l x b). No fertilizers or pesticides were used. The plants were watered daily and plants were uprooted as per lunar cycles for analysis. Eight samples were collected and observed during Shishira and Greeshma season on Pournima (full moon) and Amavasya (new moon) days. The measurements were taken thrice and average values were taken into consideration for study purpose. The variations in morphological characteristics such as length, breadth, weight, and number of roots and twigs were studied through statistical procedure of principle component analysis, which makes interpretation of all possible related variables. RESULTS: Root weight (RW), pith diameter (PD) and internodal distance (ID) were found to be increased on full moon days as compared to new moon days. The maximum RW was observed during Greeshma Aashadha Pournima. CONCLUSION: The study has shown a definite influence of lunar cycles on the growth of the plant parts assessed by RW, PD, and ID that have found to be increased on full moon days as compared to new moon days.

  Title Ecological effects of artificial light at night on wild plants Type Journal Article
  Year 2016 Publication Journal of Ecology Abbreviated Journal J Ecol  
  Volume 104 Issue 3 Pages 611-620  
  Keywords (down) Plants; wild plants; photobiology; Circadian; Ecophysiology; light cycles; light pollution; photoperiodism; photopollution; physiology; sky glow; urban ecology  
  Abstract 1.Plants use light as a source of both energy and information. Plant physiological responses to light, and interactions between plants and animals (such as herbivory and pollination), have evolved under a more or less stable regime of 24-hour cycles of light and darkness, and, outside of the tropics, seasonal variation in daylength.

2.The rapid spread of outdoor electric lighting across the globe over the past century has caused an unprecedented disruption to these natural light cycles. Artificial light is widespread in the environment, varying in intensity by several orders of magnitude from faint skyglow reflected from distant cities to direct illumination of urban and suburban vegetation.

3.In many cases artificial light in the nighttime environment is sufficiently bright to induce a physiological response in plants, affecting their phenology, growth form and resource allocation. The physiology, behaviour and ecology of herbivores and pollinators is also likely to be impacted by artificial light. Thus, understanding the ecological consequences of artificial light at night is critical to determine the full impact of human activity on ecosystems.

4.Synthesis. Understanding the impacts of artificial nighttime light on wild plants and natural vegetation requires linking the knowledge gained from over a century of experimental research on the impacts of light on plants in the laboratory and greenhouse with knowledge of the intensity, spatial distribution, spectral composition and timing of light in the nighttime environment. To understand fully the extent of these impacts requires conceptual models that can (i) characterise the highly heterogeneous nature of the nighttime light environment at a scale relevant to plant physiology, and (ii) scale physiological responses to predict impacts at the level of the whole plant, population, community and ecosystem.

  Title The Effect of Street Lights in Delaying Leaf-Fall in Certain Trees Type Journal Article
  Year 1936 Publication American Journal of Botany Abbreviated Journal Amer. J. of Botany  
  Volume 23 Issue 6 Pages 446-452  
  Keywords (down) Plants; trees; Carolina poplar; Populus canadensis; London plane; Platanus acerifolia; sycamore; Platanus occidentalis; crack willow; Salix fragilis; New York; New York City  
  Abstract Street lights in the City of New York cause a retention of the leaves of certain trees: Carolina poplar (Populus canadensis), London plane (Platanus acerifolia), sycamore (Platanus occidentalis), and crack willow (Salix fragilis). Illuminated portions of a tree retain their leaves; shaded portions of the same tree do not. One side of a tree, or the lower part, may thus have numerous leaves, while the other side, and the upper part, may be entirely devoid of foliage. A relatively weak light, at a distance of as much as 45 feet from the tip of the nearest branch, may cause retention of numerous leaves. Light intensity as low as 1 foot candle, or less, may be effective. Some leaves may be retained at least a month, others more than that, beyond the normal season. The orientation of the light with respect to the tree – i.e., north, east, south, and west – is not significant. In Populus canadensis all of the leaves ultimately fall, abscission apparently taking place at the base of the petiole. In Platanus acerifolia and Platanus occidentalis some of the leaves are retained until killed by low temperature; then some of them break off above the base of the petiole. Leaves of the Populus and Platanus species discussed remain green unusually long when receiving additional illumination. Leaves of these same trees do not emerge from the buds earlier in the spring as a result of the additional illumination.

  Title Physiological and Productivity Responses of High-wire Tomato as Affected by Supplemental Light Source and Distribution within the Canopy Type Journal Article
  Year 2016 Publication Journal of the American Society for Horticultural Science Abbreviated Journal J. Amer. Soc. Hort. Sci.  
  Volume 141 Issue 2 Pages 196-208  
  Keywords (down) Plants; tomato; LED; LED lighting; Solanum lycopersicum; intracanopy lighting; greenhouses; intracanopy supplemental lighting; daily light integral  
  Abstract The relative coolness-to-touch of light-emitting diodes (LEDs) has enabled commercial implementation of intracanopy lighting (ICL) in the greenhouse. Intracanopy lighting, which refers to the strategy of lighting along the side or from within the foliar canopy, can increase canopy photosynthetic activity, but physiological and productivity responses of high-wire greenhouse tomato (Solanum lycopersicum) to intracanopy supplemental lighting (SL) still are not yet fully understood. Two consecutive production experiments were conducted across seasons in a glass-glazed greenhouse located in a midnorthern, continental climate [lat. 40°N (West Lafayette, IN)]. Plants were grown from winter-to-summer [increasing solar daily light integral (DLI)] and from summer-to-winter (decreasing solar DLI) to compare three SL strategies for high-wire tomato production across changing solar DLIs: top lighting with high-pressure sodium lamps (HPS) vs. intracanopy LED vertical towers vs. hybrid SL (HPS + horizontal ICL-LEDs). A control treatment also was included for which no SL was provided. Supplemental DLI for each experimental period was adjusted monthly, to complement seasonal changes in sunlight, aiming to approach a target total DLI of 25 mol·m‒2·d‒1 during fruit set. Harvest parameters (total fruit fresh weight, number of fruit harvested, and average cluster fresh weight), tissue temperature, chlorophyll fluorescence, and stomatal conductance (gS) were unaffected by SL treatment in both experiments. Among the physiological parameters evaluated, CO2 assimilation measured under light-saturating conditions, light-limited quantum-use efficiency, and maximum gross CO2 assimilation (Amax) proved to be good indicators of how ICL reduces the top-to-bottom decline in leaf photosynthetic activity otherwise measured with top lighting only (HPS-SL or solar). Although SL generally increased fruit yield relative to control, lack of SL treatment differences among harvest parameters indicates that higher crop photosynthetic activity did not increase fruit yield. Compared with control, intracanopy SL increased yield to the same extent as top SL, but the remaining photoassimilate from ICL most likely was partitioned to maintain nonharvested, vegetative plant parts as well.

  Title Effect of Night Illumination on Growth and Yield of Soybean Type Journal Article
  Year 2009 Publication Journal of Taiwan Agricultural Research Abbreviated Journal J. of Taiwan Agricultural Res.  
  Volume Issue Pages  
  Keywords (down) Plants; soybeans; Taiwan  
  Abstract To evaluate the potential of soybean as a crop for bio-fuel in Taiwan, field experiments were conducted in 2006 across the island, using an Australian variety ‘Leichardt’. This study was one of the field experiments at Hemei Township, Changhua County. Soybean was seeded by hand-spreading in the fall of 2006 and harvested in 2007. Results showed that seeding of soybean by hand-spreading affected uniformity of seed germination and caused high variations in yield in this field. Seed yield of soybean reached 770 kg ha-1 under good pest management and disease control. The study also showed that night illumination is an important factor affecting growth and yield of soybean. Plants growing near the roadside (within 10–20 m) were exposed to the night light, resulting in prolonged vegetative growth and delayed blossom period for about 1 to 4 weeks. Therefore, such plants suffered from poor pod filling due to low temperature stress at reproduction stage and delayed the harvest period for about 6 weeks. Nevertheless, seed yield of soybean plants exposed to the night illumination reached 1000 kg ha-1, which was slightly higher than soybean plants without exposuring to the night illumination.
