ASSESSMENT OF THE ROLE OF FLUORESCENT ROOT AND SEED EXUDATES IN CROP PLANTS

Mostrar todas las versiones(2)

Fluorescent compounds have been reported in plant leaves, having an important biological role in the protection towards UV irradiation. It is also known that stress conditions in plants stimulate the production of some of these compounds in their aerial portion. However, less is known about their pr...
