Harvest started 93 days after sowing, and lasted for 17 days, taking the appearance of abscission zone
in the fruit peduncle as a point of harvest.
When flower appears on cotton plant several hormonal changes occur leading to increased concentration of abscisic acid up to 100 folds, as abscisic acid has role in desiccation tolerance in seed, this higher concentration of abscisic acid in flower indirectly increase concentration of ethylene and form abscission zone
on peduncle and flowers start to drop.
In no way is the "abscission area' of cannabis stalked trichomes comparable to the abscission zone
at the base of the foliage of deciduous trees, or at the base of fruits that abscise at maturity.
2006) as well as vegetative leaves due to increased cellulase activity in the abscission zone
in these organs (GUAN et al.

also forms at the base of the peduncle and may lead to premature fruit shedding.
Guinn (1998) proposes that the plant hormones ethylene and indole-3-acetic acid (IAA) promote and inhibit, respectively, the development of the abscission zone
where the boll peduncle attaches to the fruiting branch, resulting in either boll abscission or retention.
The juncture between leaf stem and tree branch slowly seals itself off, forming a corky layer called the abscission zone
Instead, he has found characters such as the presence of an abscission zone
on the petiole (Fig.
Auxin (Miles 1989, Aloni 1991, Hori 1992) and cytokinins (Elzen 1983) are found in large quantities in insect galls, although their origin is not clean Auxin flux from the leaf blade eliminates the formation of the abscission zone
in the petiole during the abscission process, and cytokinins also delay senescence and prevent abscission (e.
The ultrastructural data indicates that floral abscission too requires high protein synthesis and secretory activity of material towards cell walls of the abscission zone
cells (van Doom & Stead, 1997).
