Abstract Biological activity of boron-containing compounds (BCCs) has been well-known. Growing interest and numerous applications for BCCs have been reported. Boron and boron-containing acids show low acute toxicity in mammals but data on halogenated boroxine (HB) - dipotassium-trioxohydroxytetrafluorotr...

Abstract: Boron is one of the most important micronutrients for plants. Plants may suffer from deficiency or with boron toxicity. Boron plays a role in significant physiological and biochemical events in plants such as synthesis of the cell wall, membrane integrity, antioxidation, transport of photosynth...

The boron (B) fertilization in soybean is important to ensure great yields. Boron correction must be applied in deficient soils repairing losses, exports and leaching. The objective of this study was to evaluate the effects of doses, methods and times of application of B in soybean B content ...
BACKGROUND: An efficient regeneration protocol is a priority for the successful application of plant biotechnology. Grape nodal explants were used to develop a micropropagation protocol for Thompson Seedless and Taify cvs. Explants were cultured on MS medium supplemented with Kinetin or benzylaminopurine...
Among the main factors that affect the productivity of crops is deficiency of nutrients. Boron (B) is an essential micronutrient for plants, and sunflower is one of the most sensitive plants to deficiency of the element. Its inadequate supply can impair sunflower plants’ metabolism and...
Boron (B) retranslocation may confer greater tolerance to B deficiency or toxicity, resulting in plants and fruits with better nutritional quality. Most plants do not demonstrate phloem mobility for B; however, some plants have natural mobility and others express it under stress conditions, su...
Se efectuó un estudio para estimar el riesgo ambiental sostenible relativo ante concentraciones totales de arsénico y boro en aguas superficiales de las cuencas hidrográficas Sama y Locumba, en Tacna, Perú, a través de muestreos de tipo no probabilístico por conveniencia en puntos referenciales, du...
Our aim was to describe sperm parameters in residents from Northern Chile. We evaluated in 101 volunteers (18 and 30 years old) urinary and drinking water Boron levels using Inductively Coupled Plasma Mass Spectrometry; semen parameters were measured with standardized methods. Each individual was categor...

BACKGROUND: Rootstocks play an essential role to determining orchard performance of fruit trees. Pyrus communisand Cydonia oblonga are widely used rootstocks for European pear cultivars. The lack of rootstocks adapted to different soil conditions and different grafted cultivars is widely acknowledged in ...

Vinte plantas de abacaxi "Pérola" foram cultivadas em vasos de plástico de 10 L, em casa de vegetação, com o objetivo de caracterizar os sintomas visuais de deficiência de B nas plantas e nos frutos. Os vasos continham areia de rio lavada cinco vezes com água comum e depois duas vezes com água des...
