Book excerpt: Excerpt from Abscission of Flowers and Fruits in the Solanaceae, With Special Reference to Nicotiana: A Thesis Submitted in Partial Satisfaction of the Requirements for the Degree of Doctor of Philosophy at the University of California Although it is a matter of common observation that many plants are capable of detaching portions of the body, the underlying cause and the actual mechanism which bring about such separation are only slightly understood. The process has often been described as' One Of self-pruning by which the plant rids itself of useless portions of its body. Since abscission is sometimes confused with exfoliation, it seems desirable here to distinguish definitely between these two phenomena. It can be said that, in general, exfoliation is preceded by drying and death of the part to be cast off and that actual separa tion of the organ is accomplished by a mechanical break through dry, dead tissues. Abscission, on the other hand, is usually not preceded by drying and death of the organ concerned and its detachment is accomplished by a separation along the plane of the middle lamellae of active living cells. Abscission may be either axial or lateral. Axial abscission includes the abscission of portions of stems, shoots, entire flowers or fruits. Lateral abscission includes the abscission of leaves, petioles, sepals, petals or styles. Considerable attention has been given by investi gators to the abscission of flowers because of the theoretical detriment to crops caused by the fall of the flower before the fruit is formed.

The process has often been described asv ke of self-pruning by which the plant rids itself of useless portions of its body. Since abscission is somctimes confused with exfoliation, it seems desirable here to distinguish definitely between thme two phenomena. It can BC said that, in general, exfoliation is preccded by drying and death of the part to be cast off and that actual separa- tion of the organ is accomplished by a mechanical break through dry, dead tissues. Abscission, on the other hand, is usually not preceded by drying and death of the organ concerned and its detachment is accomplished by a separation along thc plane of the middle lamellae of active living cells. Abscission may he either axial or lateral. Axial abscission includes the abscission of portions of stems, shook, entire flowem or fruits. Lateral abscission includes the abskssion of lcavcs, petioks, sepals, pctah or styles..
