epinasty

the increased growth of the upper surface of a structure, such as a leaf, resulting in its being downcurved.

In addition, it causes epinasty, characterized by the downward bending of the leaf, decreasing the surface for light absorption, leading to disorders in the synthesis of proteins and collapse of tissue (Giafagna, 1987).

This reaction is found within the chain of symptoms caused by hypoxia in the rhizosphere, which directly affects the roots and indirectly affects the stem, finally causing the cessation of growth, epinasty and wilting of the leaves, with stomatal closure (inhibiting photosynthesis and respiration) as well as senescence and abscission (Tadeo and Gomez-Cadenas, 2008).

However, after 8 weeks of culture, necrosity, leaf epinasty, leaf abscission and hiperhidricity were observed in both, Granola and Arbolona negra cultures both in semi-solid and liquid culture.

Higher levels of ethylene ( greater than 25 ug L-1) can be damaging for plants, leading to epinasty, shorter roots and premature senescence (Holguin and Glick, 2001).

Some of the main symptoms of senescence caused by ethylene and described in cut flowers are: abscission of floral buds, flowers, and leaves, epinasty, early wilting and yellowing open petals (WILLS et al., 1998).

The petioles response to ethylene is called epinasty and should not be confused with the phototropism attributed to auxin.

Chapter 11: The control of growth and development

THE PLANT HORMONE ethylene controls a wide array of plant processes including fruit ripening, fading of flowers, organ shedding (abscission), gravitropism, petiole epinasty, abiotic stress responses, and responses to pathogens (Abeles et al., 1992; Bleecker and Kende, 2000).
