“…Interactions of this type have not yet been sufficiently investigated, however, considerations exist about the role of cytokinins as a counterbalance to the inhibiting effect of ABA on the developing flowers (MORRIS and NEWELL 1987). In addition, interactions between these two types of substances on the level of protein phosphorylation are already known (KULAEVA 1990).…”

The effect of the application of abscisic acid (ABA, lO""* mol • 1"'), benzyl adenine (BA, 10^^ mol • T'), N*'-m-hydroxybenzyl-adenosine (HBA, 10""^ mol • T') and combinations of these cytokmins with ABA on the transport of '"^C-sucrose into the developing kernels of winter wheat, their number and mass, was studied. Growth substances were applied in the period 10 to 5 days before anthesis and their effects were exammed 4 and 18 days after anthesis on ears that were detached 10 days before anthesis and then cultivated on a complete nutrient solution. The stimulating effect of HBA on the transport of ''^C-sucrose, number of kernels and their mass was higher than that of BA. ABA partly decreased the stimulating effect of cytokinins and reduced up to several days after anthesis the transport of '"'C-sucrose to the developing kernels, their number and mass. The results revealed that a higher level of cytokinins in the period before anthesis could effectively interact with the inhibiting effect of ABA in that period and influence the accumulation of assimilates in the kernels.

Decapitation of the fully-elongated fourth internode of Phaseolus vulgaris plants resulted in the disappearance from the internode of soluble acid invertase (EC 3 .2.1 .26) . This loss was prevented by local applications to the internode of indol-3yl-acetic acid (IAA) and, at the point of IAA application, the specific activity of the enzyme increased by up to 3 times its initial value within 48 h of treatment . IAA applications stimulated the acropetal translocation to the internode of 14C-sucrose applied to the subtending (second) trifoliate leaf 30 h after decapitation and the start of the auxin treatment . Labelled assimilates accumulated in the IAA-treated region of the internode . Following decapitation the concentration of hexose sugars in the internode fell and that of sucrose rose substantially, but these trends were reversed by IAA treatment . However, small local accumulations of sucrose occurred at the point of auxin application where tissue concentrations of IAA were greatest (determined using [1-14C] IAA) .Considerable quantities of starch were present in the ground parenchyma of the internodes at the start of the experiment but, in the absence of IAA, this was remobilised within 48 h of decapitation . IAA prevented starch loss at and below its point of application to the internode, but not from more distal tissues. Cambial proliferation, radial growth and lignification were stimulated in and below IAA-treated regions of the internode. These observations are discussed in relation to the hormonal regulation of assimilate translocation in the phloem .
