by the BDE-47 treatments. Their potential activity of PSII ( F v / F o ), actual light energy conversion efficiency of PSII ( Φ PSII ) and electron transport rate significantly decreased after a 96-h exposure to 2.5 µg·L −1 BDE-47 ( Li et al., 2010

.032)], this 3% difference is likely not physiologically significant because a typical leaf has an efficiency of about 80% (F v /F m = 0.8) ( Carpentier, 2005 ; Schreiber, 2004 ). The ratio of F v /F m provides an estimate of the energy conversion efficiency

conversion efficiency from metam sodium to methyl isothiocyanate ( Draper and Wakeham, 1993 ; Geddes et al., 1995 ). The difference in the amount of a.i. applied per acre of biofumigant plants and metam sodium is large and is likely the contributing factor

species of the mustard family. Moreover, the amount of glucosinolate production and glucosinolate to isothiocyanates conversion efficiency, which are highly dependent on soil and environmental conditions and management practices, governs the release of

in end breakdown products, and the fact that B. napus has been found to have a glucosinolate to isothiocyanate conversion efficiency of about half of B. juncea , disease symptom suppression and pathogen recovery in this study was similar among the

). LEDs have many advantages over conventional fluorescent lamps, including specific wavelength, low thermal output, adjustable light intensity and quality, high photoelectric conversion efficiency as well as small size and extended longevity ( Brown et al

electrical conversion efficiency ( Gomez et al., 2013 ). HPS lamps were tailored for human vision and therefore are not ideally suited for plant growth ( Bula et al., 1991 ). Earlier research has shown that the most important wavelengths for photosynthesis
