“…In searching the literature, we have found that, regardless of the treatment or process, caiiose depostion and ethylene evolution always occtir together, when both iiave been studied. For example, callose deposition and ethylene evoliition both.occur in the early stages of ieaf abscission (Brown and Addicott 1950, Osborne 1973, Beyer 1974, Poovaiah 1974 or in tobacco mosaic infected bean leaves (Nakagaki et al 1970, Stobbs et al 1977. The relationship between these two responses to various perturbations of plants would seem to be a worthwhile area of future research.…”

“…These observations, along with evidence that ethylene is produced in or near meristematic tissues (Burg and Burg, 1968;Goeschl, Pratt, and Bonner, 1967), suggest that the presence of ethylene may be related to cell division. In this connection it is relevant that Brown and Addicott in 1950 reported that no cell divisions occurred in the abscission region in bean explants exposed continuously to ethylene. This report, along with the observations of the timing of the drop in high endogenous ethylene levels (6 hr after excision) plus the anatomical evidence of the timing of the start of meristematic activity in the abscission region (6-8 hr after excision) suggest that a decrease in ethylene level triggers the onset of cell divisions in bean explants.…”

“…structural changes to the time of effectiveness of certain growth factors known to be involved in abscission. Some observations of this sort have gradually accrued (Brown and Addicott, 1950;Gawadi and Avery, 1950;Webster, 1968;Rasmussen and Bukovac, 1969). This study extends such information and elaborates the lengthy sequence of structural changes in the various tissues of the abscission region of intact plants and explants of the red kidney bean.…”

“…Many workers have shown that a low carbohydrate content in the plants promotes leaf, flower bud and fruit abscission (4,6), while addition of sucrose retards abscission (4,5,7,11,19). The fact that light intensity (23,24) and defoliation (31) promote abscission might indicate that carbohydrate deficiency plays a role.…”
