“…Application of IAA to stems of bean seedlings causes a mobilization of sugars, chiefly glucose, and soluble nitrogenous compounds to the treated region from other parts of the plants (31,24). More recently, BRUNSTETTER and coworkers (10) have studied the change of nine different kinds of minerals in bean stems treated with IAA. Significant increases in all but Ca were observed.…”

In a previous paper of this series (19), data have been presented to show that pollination in orchid flowers brings about considerable changes in their water balance. The present paper deals with the change in respiratory activity, catalase activity, and chemical constituents as consequences of pollination and auxin treatment. The general methods used in sampling and treatment of flowers are essentially the same as that earlier described (19). A general conclusion, based on all experimental facts presented in both papers, is also given here.Respiration WHITE (35) noted an increase of respiratory rate and also of respiratory quotient after pollination in a number of plant species. A critical examination of her data, however, would seem to show that the respiratory quotient was unusually low for the non-pollinated plants, indicating that some constant errors might have been involved. Moreover, in most of the plants she used, fertilization is known to follow pollination more or less closely. It is therefore not safe to attribute the observed effects, if valid, to pollination alone. Further work is needed on the effect of pollination on respiration.In the work reported here respiration was measured as the amount of 02 taken up per unit of time per unit of dry weight. A Warburg respirometer of the constant volume type was employed. All experiments were run at 250 + 0.20 C.Preliminary study showed that when tissue sections were floated on phosphate buffer solution at a pH of 5.8 the liquid tended to enter the intercellular spaces and gave the tissues a translucent appearance. Therefore, the use of the buffer solution was omitted and the tissues were put directly into the flasks without any added liquid. Two tenths of a milliliter of 20% KOH on filter paper was used in the center well. After equilibration, readings were taken at 15-or 30-minute intervals until several constant values had been obtained. An average reading of four to six intervals was usually taken to represent the respiration value.The respiratory quotient was obtained by using the same sample in the same flask, instead of using two separate flasks. Readings were first taken without KOH in the center well; KOH was then added and readings were I Present address:

“…shown to accumulate at regions where lAA was applied (Mitchell and Martin, 1937;Stuart, 1939;Brunsetter et al, 1948). These experiments, however, took place over several days, and it is possible that the primary effect of lAA was to induce a region of rapid growth to which nutrients were attracted to form new cell materials.…”

“…This observation may suggest that the distribution of P32 is associated with the distribution of the growth regulators. In 1948, Brunstetter et al (13) demonstrated that when bean plants were treated with 3-indoleacetic acid, the P content in the treated stem increased about 5 times over that of the control after 148 hours. Our result showed that the accumulation of P32 in IAA treated stems was the same as compared to the control stems.…”

Accumulated evidence has indicated that the physiological effect of 2,4-dichlorophenoxyacetic acid (2,4-D) in plants may function through its effect on processes of respiration (1,2,3,4,5) as well as on photosynthesis (6). Since the precise mechanism by which plant cells respond to 2,4-D has yet to be elucidated, and the participation of phosphorus in biological oxidation-reduction reactions had been found in both higher animals and microorganisms, an investigation was initiated to study the comparative effects of 2,4-D and other plant growth regulators on phosphorus metabolism in order to clarify, in part, the herbicidal effect of 2,4-D.The immediate objectives of the work reported here are as follows: the comparative effects of 2,4-D and other plant growth regulators on (1) the phosphorus uptake, (2)
