“…Thus translocation was obtained by dehydrating the plants (Biddulph, Cory, and Biddulph 1959;Taylor, Moore, and Drinkwater 1961), by treatment with diethyl ether (Bukovac, Wittwer, and Tukey 1956;Biddulph, Cory, and Biddulph 1959), and in some instances by treatment with 2,3,5-triiodobenzoic acid (Kessler and Moscicki 1958;Bukovac and Wittwer 1961). Taylor, Moore, and Drinkwater (1961) were unsuccessful when they used the latter compound as a translocating agent.…”

SummaryA series of water-culture experiments was conducted with broad bean (Vicia faba L.), common stock (Mathiola incana R. Br.), subterranean clover (Trifolium Bubterraneum L.), and garden peas (PiBum Bativum L.) grown in normal-and lowcalcium nutrient solutions. Leaves of the plants were either injected or s,,!rfacetreated with an aqueous solution of 45CaCh with and without various additions to the dose. The subsequent distribution of 45Ca in the plants was determined by means of radioautographs and radioassays.In each species, where nothing was added to the dose, there was negligible movement of 45Ca from the treated leaf. With broad bean or common stock or both, the addition of small amounts of EDTA (disodium salt) or HCI or both, or of citric acid, caused marked movement of 45Ca in an acropetal direction in both the normal and calcium-deficient plants. Marked accumulation of 45Ca occurred in the epidermal hairs and anthers of common stock. There was also some evidence of retranslocation of 45Ca in this species.A series of experiments with subterranean clover confirmed the effect of EDTA in promoting mobility of 45Ca when either injected into a leaf or applied to the uninjured leaf surface. With low concentrations of EDTA, movement was mainly acropetal, but with a high concentration marked basipetal movement to the roots also occurred.When graduated amounts of non-radioactive calcium (as CaCh.6H20) or equivalent amounts of magnesium (as MgCh.6H20) were added to the dose, increasing mobility of the injected 45Ca occurred in both normal and calcium-deficient plants. With the highest levels of calcium or magnesium additions, movement of 45Ca occurred throughout the plant including the cotyledons and the whole of the root system.

“…Biddulph et al (2) demon-st~ated that foliarly applied TIBA did not enhance 45 Ca transport from leaves of reel kidney bean (Phaseolus vulgaris) plants within a 24-hour period. Taylor et al (20) found similar results on tomato (Lycoper-si~on sp.) sprayed to runoff with 100 ppmw TIBA.…”

Effect of Root‐absorbed 2,3,5‐Triiodobenzoic Acid on Nutrient Absorption and Growth by Soybeans¹

Foliar application of 2,3,5‐triiodobenzoic acid (TIBA) has been recently used on soybeans [Glycine max (L.) Merr.] to enhance yields. Root application appeared as an alternative naethod of applying TIBA to the plant. This study was initiated to provide information on effects of root‐absorbed TIBA on growth, nutrient absorption, and nutrient distribution. Plants were grown, in Hoagland solution with TIBA at eight levels from 0 to l0 ppmw. Nutrients absorbed were determined by their disappearance from samples taken periodically. Although young leaves and internodes showed no visible response at concentrations lower than 5 ppmw. typical symptoms were observed at 5 and 10 ppmw TIBA. The 10‐ppmw dosage reduced elongation of the stems. Roots were more sensitive than tops to TIBA, and morphological effects were observed as low as 0.1 ppmw. Shoot/root ratios showed that TIBA equally influenced the dry weights of these tissues. TIBA appeared to enhance the rate of P uptake from the nutrient solution. Within a 6‐day period 5 ppmw TIBA enhanced total P uptake about 25% above controls, while absorption of NO3‐N, K, Ca, Mg, Mn, and Fe was not influenced.

“…Those authors based their conclusion that 45Ca was exported on the specific radioautographic distribution pattern in the primary leaves. We were, however, unable to reproduce the radioautographic results either with generally accepted methods or even with critical methods (Biddulph et al 1959, Taylor et al 1962 as were used by Greene and Bukowac (1968).…”
