rice. For example, low light results in a prolonged
period of growth and also increases plant height and
leaf area (Ren et al, 2002; Liu et al, 2009). Before the
heading stage, low light gives rise to a pronounced
decrease in fertile panicles of rice plants. After the
heading stage, shading causes impairment of the net
photosynthetic rate as well as lower dry matter
accumulation and sink capacity in rice plants, and this
significantly
