“…The heading time of wheat does not seem to be affected by blue light (400-500 nm), but plants grown in high-fl uence-rate green-yellow light (500-600 nm) require fewer days to reach 50% heading ( Kasajima et al, 2007 ) Analysis of inductive wavebands showed that 540 nm imposed the strongest flowering stimulation effect ( Kasajima et al, 2008( Kasajima et al, , 2009 ).…”

Light passing through or refl ected from adjacent foliage provides a developing plant with information that is used to guide specifi c genetic and physiological processes. Changes in gene expression underlie adaptation to, or avoidance of, the light-compromised environment. These changes have been well described and are mostly attributed to a decrease in the red light to far-red light ratio and/or a reduction in blue light fl uence rate. In most cases, these changes rely on the integration of red/far-red/blue light signals, leading to changes in phytohormone levels. Studies over the last decade have described distinct responses to green light and/or a shift of the blue-green, or red-green ratio. Responses to green light are typically low-light responses, suggesting that they may contribute to the adaptation to growth under foliage or within close proximity to other plants. This review summarizes the growth responses in artifi cially manipulated light environments with an emphasis on the roles of green wavebands. The information may be extended to understanding the infl uence of green light in shade avoidance responses as well as other plant developmental and physiological processes.

“…Recent reports suggest that the heading is accelerated by green light (Kasajima et al, 2007;2008). The effect of green light may not be involved in the photoperiodic and vernalization responses (Kasajima et al, 2008).…”

“…We previously reported that the heading rate in wheat was significantly correlated with the ratio of energy in 500-550 nm range compared to that in the whole spectral range (Kasajima et al, 2007). However, the most effective wavelength within the 500-550 nm range is still unknown.…”

: The response spectrum for green light induced-acceleration of heading in wheat cv. Norin 61 was investigated using narrow-bandwidth (10 nm) green light within the range of 520-550 nm. Heading was observed from approximately 30 days after emergence. The earliest heading was observed at 540 nm, which suggests the presence of a green light photoreceptor different from hitherto known photoreceptors.

“…Growth, yield and quality of a plant species are influenced by environmental factors such as water, temperature, photoperiod, radiation, shading and soil nutrient status (Chapman et al, 1993;Miller et al, 1993;Kobata et al, 2000;Kakiuchi and Kobata, 2004;Cohen et al, 2005;Hossain and Ishimine, 2005;Sharma et al, 2006;Akamine et al, 2007;Kasajima et al, 2007).

: The effects of relative light intensity (RLI) on the growth, yield and curcumin content of turmeric (Curcuma longa L.) were examined in Okinawa, Japan. The plants were shaded with white nets with different mesh sizes for maintaining respective RLI. Five RLI, 100 (without shading), 82, 79, 73 and 59% in 200482, 79, 73 and 59% in −200582, 79, 73 and 59% in and four RLI, 100, 68, 52 and 48% in 200582, 79, 73 and 59% in −2006 were evaluated. In the fi rst experiment, plant height increased markedly, but the number of leaves and tillers, and SPAD value increased slightly in the plants grown at 59−82% RLI compared with control (without shading). Turmeric shoot biomass and yield increased significantly at 59−82% RLI and they were highest at 73% RLI in the fi rst experiment. Curcumin content of turmeric increased markedly at 59−73% RLI as compared with the control in the fi rst experiment. Similar results in plant growth, shoot biomass, yield and curcumin content were obtained in the second experiment, but the effects of RLIs were smaller than in the fi rst experiment because of late planting. This study indicates that turmeric is a partial shadetolerant plant that could be cultivated at around 59−73% RLI for higher yield and curcumin content in Okinawa. However, the degree of RLI required for better turmeric cultivation may vary with the place, year and irradiance level.
