Effect of 2,4-Dichlorophenoxyacetic acid Application on Activity and Composition of Mitochondria from Soybeans

Some effects of 2,4-dichlorophenoxyacetic acid on soluble nucleotides & nucleic acid of soybean seedlings

“…PROTEIN & NUCLEIC ACID: The general morphological and growth responses to 2,4-D (5 X 10-4 M in the experiments reported) were essentially those often reported, and are described in a previous paper (16). Elongation of root and shoot of treated intact plants was almost completely inhibited, apparently due to inhibition of both cell division and cell elongation (34).…”

Effects of Calcium, Indoleacetic Acid & Distance From Stem Apex on Potassium & Rubidium Absorption by Excised Segments of Etiolated Pea Epicotyl

“…The tissue samples were wet ashed by adding concentrated nitric acid and gently heating to dryness twice or more; the samples were 'Received revised manuscript Oct. 16 then countedI using a thin-winidow Geiger tube. Under the conditions of these experiments Rb86 appears to serve as a suitable label for K and the estimates of K uptake are based on this technique.…”

“…Another possible relationship involved is the dtevelopment in growing cells of mitochondria which appear to require both Ca (5) and auxin (7,16). Under appropriate conditions the increase in respiration induced by auxin may apparently be related to an increased Rb influx rate (11).…”

Effects of X irradiation on corn seed

“…When enzymatic activities were measured from tissue at different ages (table VI), the same type of changes in activity was observed as that caused by seed X irradiation (table V). (8,11,15,16).…”
