“…The auxin was presumed to act directly on the abscission zone. The greater speeding from a given concentration, applied proximally rather than distally, they attributed to "transport di fferences" [(11), p. 55 0] , although as mentioned in the previous section the only direct test in bean petioles showed no detectable transport either of native hormone or of added IAA (82).…”

“…Shoji & Addicott obtained no detectable diffusible auxin from the base of short sections cut from the stalk of fully grown bean leaves even when synthetic IAA was added to the opposite end (82). The absence of detect able transport of their added IAA is probably largely due to the unusually low concentration added-lOO foLg per liter.…”

The research of many men during the last twenty years has gone toward elucidating the internal factors which control the longevity of two importan t types of plant organs-leaves and fruits. This work, which one would expect to have general interest for developmental biologists, has not been as familiar to them as it might be because most of the papers which could be considered to treat longevity have emphasized the "abscission" side of the research. The emphasis on abscission is quite understandable: there are important economic aspects of leaf abscission and of fruit abscission (e.g., inducing leaf abscission in cotton plants for the mechanical picker, and preventing fruit abscission in some of the tree crops like apples and figs) . Consequently, many of the papers have been published in agricultural research journals , where the practical aspects of the research were emphasized.This review will consider the gradual development of our current under standing as to the internal factors in the plant which control the longevity of leaves and fruits. The extensive literature on external agents which will a rtific ally induce abscission will not be discussed, since it has recently been authoritatively reviewed by Addicott & Lynch (2), and since it is not par ticularly informative concerning the internal controlling factors, despite its value in field practice. Special emphasis will be placed on relating a given piece of research to previous research, both because of general scientific obligation, and because abscission researchers have been unusually lax in doing so. In particular, the early German authors (44,45,46,67) have, in the reviewer's opinion, not been given adequate credit by English-speaking authors. [No "holier-than-thou" attitude is suggested: the author has erroneously attributed to Myers credit that should have gone to Laibach and Mai (99), and undoubtedly will have overlooked some proper references in this review. But the aim and the obligation is to be as fair as human failings allow.]Among the papers published since the last review that are not herein considered in detail are those of Hall et at. (26,27,51,52, 53) and Haccius & Nies (23,24,25). Also omitted is consideration of the effects of position with respect to gravity, fully treated by Terpstra (86) and Vendrig (93, 94) . Of papers published before the last review, DostaJ's 1951 paper on correlative effects on leaf abscission in woody plants should be noted (14) .

“…In the past, abscission studies with bean have commonly been done with NAA, since Shoji and Addicott (11) showed that IAA is readily destroyed in the bean petiole. The relevance of these NAA experiments has been criticized by Addicott (2) in the context that synthetic NAA may have antiauxin activity, thus serving to lower the effectiveness of endogenous auxin rather than acting as an auxin.…”
