Spectral Irradiance Available for Turfgrass Growth in Sun and Shade
Assessment of spectral quality of deciduous shade, coniferous shade, building shade, and full sun in a natural environment common to turfgrass growth throughout a day and throughout a growing season indicated relationships among blue, red, and far-red irradiance that influence many plant responses were affected by both shade source and shade density.
Hartmann's Plant Science: Growth, Development, and Utilization of Cultivated Plants
The next chapter discusses the history, trends, issues, and challenges in Plant Science as well as the challenges faced in the development of knowledge of plant architecture and management.

Growth of Dendranthema ×grandiflorum (Ramat.) Kitamura under Various Spectral Filters
Spears' (nonpinched and pinched) and 'Yellow Mandalay' (pinched) chrysanthemums were grown in growth chambers equipped with panels filled with liquids that served as spectral filters. Light quality…
Plant Height Control by Photoselective Filters: Current Status and Future Prospects
The recent developments in light quality manipulation as a nonchemical alternative for greenhouse plant height control are discussed.
Interpretation of Light Quality Measurements and Plant Response in Spectral Filter Research
Results suggest that broad band R: FR ratio correlated more closely to above plant responses than the narrow band R : FR ratio, suggesting that involvement of blue light should not be ignored in expressing plant response to light transmitted through CuSO4 filters.
Development of Chrysanthemum Meristems Grown under Far-red Absorbing Filters and Long or Short Photoperiods
- M. McMahon
- 1 September 1999
The results indicate that if FR- absorbing filters are used to regulate height of chrysanthemum and possibly other photoperiodic plants, the time of flowering may be affected, however, if artificial shortPhotoperiods are imposed with the use of blackout cloth, FR-absorbing filters do not affect flowering response.
Influence of Spectral Filters on Height, Leaf Chlorophyll, and Flowering of Rosa × hybrida ‘Meirutral’
Plants were significantly shorter and had higher leaf chlorophyll when grown under the reduced FR/R filter and the number of flower buds and number of buds showing color at termination of the experiment was not affected by light quality treatments.
