IN the course of a study on the chemical retardation of soil reduction as a remedy for physiological disorders of the rice plant, we observed that despite this retardation by calcium nitrate and manganese dioxide the foliar symptoms persisted in one of the four soils studied.

Boron Toxicity: the Importance of Soluble Boron
2002The function of boron in plants has often been associated with cell wall bound insoluble boron. This was mainly due to the fact that B-related nutritional disorders clearly lead to a structural damage of the cell wall, and that the cell wall bound B-RGII-complex has been isolated and characterized in detail.

Inhalation toxicity studies with boron trifluoride
Toxicology and Applied Pharmacology, 1986An acute study of boron trifluoride (BF3) in rats indicated the 4-hr LC50 to be 1.21 mg/liter. In a 2-week study, all animals exposed to 180 mg/m3 died prior to the sixth exposure, rats exposed at concentrations of 66 and 24 mg/m3 showed clinical signs of respiratory irritation, body weight gain depressions, increased lung weights, and depressed liver ...

TOXIC EFFECTS OF BORON ON MALLARD REPRODUCTION
Environmental Toxicology and Chemistry, 1989Abstract Boron, a naturally occurring trace element generally considered environmentally innocuous, was documented to severely impair mallard reproduction. Boron is leached from irrigated agricultural soils and transported in drainage water that contaminates wetlands.

Toxicity of boron to the duckweed, Spirodella polyrrhiza
Chemosphere, 2002Boron is an essential nutrient for plants and the potential exists for efficient removal of this element by wetland treatment systems due to accumulation by plants. To evaluate the efficacy of using Spirodella polyrrhiza to treat boron-contaminated wastewater or to be a suitable species for removing other nutrients from boron-containing wastewater the ...

Phytohormones in plant responses to boron deficiency and toxicity
Journal of Experimental Botany, 2022AbstractBoron (B) is an essential element for plant growth. Many agricultural soils around the globe have either insufficient or excessive amounts of available B, with major implications for crop production. Understanding major limitations imposed by B nutritional disorders may allow breeding crops for improved B use efficiency as well as make them ...

It has been hypothesised that there is a narrow range of supply between boron (B) deficiency and toxicity in plants. Two solution culture experiments were conducted to study the response of sunflower (Helianthus annuus L.) cv. Hysun 31 to potentially-deficient and potentially-toxic supplies of B. The concentration of B in the youngest mature leaf blade

Boron toxicity in soil solution
Australian Journal of Soil Research, 1988The relationship between soil solution boron concentration and the dry-matter accumulation and boron concentration in sunflower (Helianthus annuus cv. Hysun 31) was investigated in a 14-day study in a controlled environment. Plants were grown in each of six soils previously equilibrated with various levels of boron applied as H3BO3. The soil, wet to 10

Abstract Radlands Crimson strawberries were grown in a glasshouse with 7 rates of applied boron. Wood shavings mulches with different boron concentrations were also applied as separate treatments. Boron toxicity symptoms were produced in leaves by boron rates of 0.32 kg ha‐1 and greater on a soil containing 1.6 ug B g‐1 of hot water extractable boron ...
