1. Lanolin emulsions containing various growth-regulating chemicals were sprayed on attached bean leaves and the plants were subsequently placed in darkness, together with controls. Quantitative analysis of the starch and dextrin content of the leaves showed that application of sprays containing indoleacetic, naphthaleneacetic, indolebutyric, indolepropionic, and naphthoxyacetic acids resulted in marked increase in the rate of starch digestion. Phenylacetic acid resulted in only a slight… Expand
Mineral Composition of Bean Stems Treated with 3-Indoleacetic Acid
1. Lanolin paste alone or lanolin paste containing 2% 3-indoleacetic acid was applied to the surface of middle portions of the first internodes of young bean plants (Phaseolus vulgaris) in a ringExpand
Effect of 2,4-Dichlorophenoxyacetic Acid on the Readily Available Carbohydrate Constitutents in Annual Morning-Glory
TLDR
Carohydrate reserves were rapidly depleted in the flower buds, and also in the roots, of the sprayed plants, a response of significance in connection with the use of 2,4-dichlorophenoxyacetic acid in the control of weeds. Expand
Effects of Growth-Regulating Substances on Shoot Development of Roses During Common Storage
1. Experiments conducted with rose bushes during common storage in two seasons, 1939-1940 and 1940-1941, indicate that growth-regulating substances will inhibit the vegetative buds so that the plantsExpand
Interrelation of Organic Materials in the Growth Substance Response
TLDR
The most obvious cytological change in response to the growth substances in both the bean and tomato was the great increase in size of the nucleolus, and no changes occurred in the nucleoli of plants cultured in a sugar medium in the absence of growth substances. Expand
Relation of Temperature to the Selective Herbicidal Effects of 2,4- Dichlorophenoxyacetic Acid
TLDR
Field experiments have demonstrated that dormant Plantago lanceolata in frozen ground, having some living leaves, when treated with the acid or its sodium salt is killed when the plants are placed under temperature conditions favorable for growth. Expand
Effects of 2,4-Dichlorophenoxyacetic Acid on the Ripening of Detached Fruit
TLDR
Treated fruits attained a full yellow color and excellent flavor, even though they were subjected to drier air and lower temperature conditions than is usually maintained in their commercial ripening, while untreated fruits failed to ripen during this period. Expand
Some Effects of 2,4-Dichlorophenoxyacetic Acid on Starch Digestion and Reducing Activity in Bean Tissue Cultures

  • 1948
TLDR
Reducing activity of the endodermis, phloem, cambium, and xylem parenchyma was demonstrated by the use of triphenyl tetrazolium chloride in sections of bean stem cultured on nutrient agar containing 1% starch and 10 mg. Expand
Hyperauxiny in Crown Gall of Tomato
TLDR
The significance of the finding that the growth disturbance known as crown gall is associated with disturbance in auxin relations (dysauxiny) is discussed with reference to the hypothesis that auxins play roles in normal and in healthy growth of plants and to the causal complex of gall development. Expand
Movement of 2,4-Dichlorophenoxyacetic Acid Stimulus and Its Relation to the Translocation of Organic Food Materials in Plants
TLDR
The stimulus resulting from treatment with 2,4-dichlorophenoxyacetic acid was not readily translocated from leaves of bean plants whose sugar content was relatively low, such as those exposed to extended periods of darkness or to CO2-free air in light. Expand
Responses of Elodea densa to Growth-Regulating Substances
TLDR
The principal gross responses noted were axillary bud development, shoot elongation, the number of roots emerging, time and order of their appearance, their lengths, and root-hair development of Elodea. Expand

TLDR
Growth substance studies with vascular plants have probably been emphasized in the past because in these plants correlations, formation of organs, tropisms, and modifications of growth may be studied to better advantage than in algae. Expand
