“…This suggests that the decreases in respiration rate were largely due to crop growth inhibited by enhanced UV-B. It has been well recognized that enhanced UV-B inhibited crop growth and decreased the biomass of crop Kakani et al 2003;Kadur et al 2007;Yao et al 2008). Kadur et al (2007) assessed the impact of UV-B on soybean (Glycine max) growth by filtering off UV-B radiation, and found that exclusion of UV-B enhanced the fresh weight, dry weight and biomass of soybean.…”

“…It is well documented that enhanced UV-B inhibits crop growth Kakani et al 2003;Kadur et al 2007;Yao et al 2008) and influences indirectly the soil microbial populations and activities (Johnson et al 2002(Johnson et al , 2003Robson et al 2004). Crop growth and soil microbial activities are the main factors influencing plant respiration and N 2 O emissions from croplands, however, enhanced UV-B effects on the greenhouse gases emission have rarely been examined in agroecosystems.…”

To gain insight into enhanced ultraviolet-B (UV-B) radiation effects on agroecosystem respiration rates and nitrous oxide (N 2 O) emissions, pot and field experiments were conducted in the 2004 and 2006 soybean-growing seasons, respectively. The enhanced UV-B radiation treatments were simulated by a 20% increase in its intensity. The respiration rates and N 2 O fluxes were measured by a static opaque chamber-gas chromatograph method. Results showed that the enhanced UV-B radiation did not change the seasonal patterns of ecosystem respiration and N 2 O emission. Compared to the controls, however, the enhanced UV-B reduced the respiration rates by 43.3% (P = 0.015) and 44.8% (P = 0.002) over the entire soybeangrowing seasons in 2004 and 2006, respectively. Similarly, the enhanced UV-B radiation reduced seasonal N 2 O emissions by 33.5% (P = 0.023) and 42.4% (P = 0.006) in 2004 and 2006, respectively. Our findings suggest that enhanced UV-B radiation may lead to a decrease in agroecosystem respiration rates and N 2 O emissions from croplands. To estimate the overall effects of enhanced UV-B radiation on greenhouse gas emissions from agroecosystems, nevertheless, more field measurements deserve to be carried out in various cropping systems.

“…High levels of ultraviolet radiation influence negatively on carbon assimilation rate and growth of plants [31]. The alterations in plant height, branching pattern and leaf size of soybean plants were observed in UV-excluded sunlight when compared to control plants.…”

“…In addition, the exclusion of solar UV-B and UV-B/A radiation increased the plant height (30% for exclusion of UV-B and 60% for exclusion of UV-B/A). Thus, the solar spectrum causes changes in soybean growth and morphological developments [31]. The exclusion of the UV-B/A radiation also caused elongated internodes in soybean plants, resulting in greater plant height.…”

The soybean plant architecture in relation to better solar radiation interception and production gain is an aspect that requires a better understanding, since soybean is an important crop worldwide. The genetic traits, management and environmental conditions are points that further extend the range of issues on crop productivity. The light quality is measured by the red/far-red (R/FR) ratio (R ∼ 660 nm, FR ∼ 730 nm). This affects the plant growth and morphological developments in different ways. The plant leaves change their angle during the day to better intercept radiation. This heliotropic movement and some computational models together have been used to enhance some agricultural practices. Soybean plant is dependent on the interaction between genotype and environment. Thus, the enhanced understanding in relation to photosynthetic activity, grain yield by light interception efficiency and culture protection managements in soybean are covered.

“…Al igual que en el caso del crecimiento, los efectos de la radiación en el peso de las plantas pueden variar con la especie vegetal estudiada. Diferentes autores han constatado que la producción de biomasa (peso fresco-seco) era inhibida por la radiación UV-B o UV-A+B (Krizek et al, 1997;Kadur et al, 2007), aunque otros estudios obtuvieron resultados opuestos, como un efecto nulo (Garzón, 2015b) o un incremento del peso seco vegetal (Liu et al, 2005).…”
