Effect of Composted Organic Matter on Boron Uptake by Plants
B is one of the seven essential micronutrients Boron uptake by plants is controlled by the B level in soil solution required for the normal growth of most plants. rather than the total B content in soil. The affinity of organic matter for However, the range of B concentrations in the soil soluB can affect B uptake by plants because of changing B concentration in tion causing neither deficiency ...
متن کاملBoron Distribution and the Effect of Lime on Boron Uptake by Pansy, Petunia and Gerbera Plants
Reports of boron (B) deficiency have become more prevalent in pansy (Viola ×wittrockiana), petunia (Petunia ×hybrida), and gerbera (Gerbera jamesonii) plug production. When symptoms are observed in production the presence and severity of symptoms have no obvious pattern; symptomatic plants can be located adjacent to asymptomatic plants in the same plug flat. The availability of B in the soil de...
متن کاملIn Vitro Analysis of Boron - 10 Uptake and Neutron Beam Design for Boron Neutron
Boron Neutron Capture Synovectomy (BNCS) has been proposed as a novel application of the o 1 B(n,a) 7Li reaction for the treatment of Rheumatoid Arthritis (RA). RA is an autoimmune disease of the joints characterized by an inflammation of the synovium, the membrane lining the joint capsule. If drug regimes fail, treatment options are surgical synovectomy or radiation synovectomy. BNCS has advan...
متن کاملUptake and Distribution of Boron in Coconut and Paurotis Palms
Natural distribution patterns of boron (B) among leaves within a canopy, among leaflets within a leaf, and within single leaflets were determined for coconut palm (Cocos nucifera L.) and within leaves for paurotis palm [Acoelorrhaphe wrightii (Griseb. & H. Wendl.) Becc.]. Leaf B concentrations did not vary significantly among leaves within the canopy or among leaflets within a single leaf for c...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
