Effects of Low Light after Heading on the Yield of Direct Seeding Rice and Its Physiological Response Mechanism

Plants, 2023
As a photophilous plant, rice is susceptible to low-light stress during its growth. The Sichuan Basin is a typical low-light rice-producing area. In this study, eight rice varieties with different shade tolerances were studied from 2021 to 2022.

Shade Avoidance [PDF]

The Arabidopsis Book, 2012
The presence of neighboring vegetation modifies the light environment experienced by plants, generating signals that are perceived by phytochromes and cryptochromes. These signals cause large changes in plant body form and function, including enhanced growth of the hypocotyl and petioles, a more erect position of the leaves and early flowering in ...
