    1% v/v PA. Sublethal rates of glufosinate and PA were used so as not to kill plants and to monitor glufosinate absorption, translocation, and metabolism in live plants. Immediately after spraying, one leaf of each plant (common milkweed, 2 nd leaf pair, sicklepod, outward most leaflet of the first leaf, common lambsquarters, 2 nd leaf pair. salt absorption and the different theories related to salt absorption by plants, mechanism of active salt absorption, finally the function and deficiency of the major elements to plants. b4.

    Translocation • Occurs in Phloem glutamic acid, glutamine • Types of sugars • sucrose main transport sugar: non-reducing sugar • some species: raffinose, stachyose transported • sugar alcohols: sorbitol, mannitol. Nitrogen compounds • Transport from the root • Amino acids. Mineral Salts Absorption in Plants details the contemporary knowledge regarding the mineral salt absorption mechanisms of plants. The title first covers the history of mineral salt absorption in plants, and then proceeds to tackling the experimental materials and methods. Next, the selection discusses the mechanisms of ion transport.

Abstract. Graduation date: Studies were conducted to determine the influence of formulation and molecular configuration of some chlorinated-phenoxyalkylcarboxylic acid herbicides on their absorption, translocation and metabolism in bigleaf.

Some Factors Affecting Absorption and Translocation of Zinc in Citrus Plants. Wallihan, L. Heymann-Herschberg Plant Physiology Jul31 (4) ; DOI: /ppCited by: Some Factors Affecting Absorption and Translocation of. Abstract approved (Major professor) Studies were conducted to determine the influence of formulation and molecular configuration of some chlorinated-phenoxyalkylcarboxylic acid herbicides on their absorption, translocation and metabolism in bigleaf maple, Acer macrophyllum, Pursh.

Some factors affecting absorption and translocation of phenoxyalkylcarboxylic acids in plants / carbamate] were carried out using glasshouse and field-grown bracken plants.

Translocation of. KOONTZ AND BIDDULPH-ABSORPTION AND TRANSLOCATION4 series, in duplicate, at mAI phosphorus gave the following average translocation percentages: H3P*04, ; NaH2P*04, ; Na2HP*04, ; Na3P*04, No injury from H3P*04 was evident at this lower concentration.

It seems unlikely that the rather large variability in individual plants can be attributed to chance dif. The aim of this study was to evaluate the absorption, translocation and metabolism of 14 C‐aminocyclopyrachlor in young plants of Ipomoea purpurea and Ipomoea triloba.

Assessments were performed at 3, 6, 12, 24, 48 and 72 h after treatment (HAT) for the study of absorption and translocation. This review is restricted to an examination of the literature on the environmental and chemical factors that affect foliar absorption and translocation of 2,4-dichlorophenoxyacetic acid (2,4-D.

Plants were wet-ashed in 2 ml 6 N perchloric acid A.R. grade and ml nitric acid (A.R. grade specific gravity ). Phosphorus was estimated in the clear solution using the method of Allen (). Determination of radioactivity in root segments Individual root segments were placed on aluminium planchettes and dried under an infrared lamp.

Theories of Translocation for Plant. Plants absorb minerals from the soil and translocate them to other parts of the body. Minerals are absorbed in the form of soil solution contained in the pore spaces between the soil particles and the root soil solution contains the mineral salts in the dissolved state.

The factors affecting the absorption and translocation of simazine by young barley plants in short-term experiments in water culture have been investigated.

Chromatographic examination of the xylem sap indicated no extensive breakdown of the herbicide in the transpiration stream. Earlier it was thought that the absorption of minerals takes place in plants along with the absorption of water.

In fact, the process of mineral absorption and water absorption are two separate processes. In order to absorb any minerals from the soil, it should be dissolved in the water. Plants absorb most of the minerals through the roots.

Some factors affecting absorption and translocation of zinc in citrus plants. Absorption of fluazifop-butyl and translocation of the radiolabel from 14 C fluazifop-butyl were similar in plants of both biotypes. Leaves of both resistant and susceptible species rapidly hydrolyzed fluazifop-butyl to fluazifop acid.

However, a more rapid rate of metabolism of fluazifop acid was shown in the resistant plants to unknown. Some Factors Affecting Absorption and Translocation of Zinc in Citrus Plants. 1, 2. Wallihan and L. Heymann-Herschberg 3 Specht AW.

MINERAL COMPOSITION OF CHLOROTIC ORANGE LEAVES AND SOME OBSERVATIONS ON THE RELATION OF SAMPLE PREPARATION TECHNIQUE TO THE INTERPRETATION OF RESULTS. Physiological factors 1. Gastric motility. It has large effect. Some disorders like diabetic neuropathy causes gastric stasis and decrease the drug absorption.

Due to drug treatment some time motility is increased or decreased. The excessively rapid movement of GIT impairs absorption. Water Absorption System in Plants: Pathways; Mechanism and other Details.

Plants have the potentiality to absorb water through their entire surface right from root, stem, leaves, flowers, etc. However, as water is available mostly in the soil, only the underground root.

Ashton, F. M.: Effect of gibberellic acid on absorption, translocation, and degradation of 2,4-D in red kidney beans. Weeds 7, (). CrossRef Google Scholar. Transpiration, the loss of water vapor from plants, is a physical process that is under control of both external physical and physiological radiation provides the energy source for transpiration.

In general, the rate of transpiration is proportional to the gradient in water vapor concentration between sources of water within the plant and the bulk atmosphere and the total. When 65Znis introduced into the rooting media of plants, translocation of the radioactive tracer to other parts of the plant usually occurs within a few hours.

Thorne () reviewed some of the earlier work on the effects of phosphorus, iron, nitrogen, and light on the translocation of zinc in plants. Plants with PDS applications showed an increase in absorption from the four- to eight- to twelve-leaf stages and reached a plateau at the leaf stage.

Translocation of 14C-glyphosate to roots was greater at all growth stages with PDS treatments than with POST treatments. Herbicide placement did not affect.Day BE. The Absorption and Translocation Of 2,4-Dichlorophenoxyacetic Acid by Bean Plants.
