Herbage Abstracts56— More nutritionally demanding than other Brachiaria species.

Collected at 1, m asl in a 1, mm annual rainfall region of Kenya. The dose of Gy radiation of seeds and regrowth phase 2 gave the best interaction. This reduction was from Breeding objectives for Brachiaria species in Colombia are for increased resistance to spittlebugs, leaf-cutting ants, and other biotic constraints, better edaphic adaptation, especially to infertile soils and improved nutritive value.

Keywords Azadirachta brizantya Brachiaria brizantha cv. Well accepted by grazing stock.

Widely planted in tropical America. Effect of gamma radiation on germination and physiological aspect of wheat Triticum Aestivum L. The water culture method of growing plants without soil. Tolerance to Mn varies brizqntha accessions. Collected in Nukuru, Kenya at 1, m asl.

Seed may be dormant for up to 6 months after harvest. The levels of Si in the plant tissue reduced as a function of the NaCl concentration in the solution Figure 1b.


In Eastern Venezuela, used in mixtures with B.

Effect of defoliation on grass growth. Marandu and Arachis pintoi cv. Best adapted to the humid and sub-humid tropics with 1,—3, mm AAR, but will also grow in the more arid regions of the tropics with rainfall somewhat below 1, mm. With the increasing Si in the solution, an increase was seen in SDW to Effects of salt stress and silicon nutrition on cholorophyll content, yield and yield components in fennel Foeniculum vulgare Mill. With the acceleration of senescence and the phenological cycle, photoassimilates and leaf nutrients were mobilised for seed production and lignification of supporting tissue such as stalks TAIZ; ZEIGER,which had a negative effect on the growth variables.

The species is predominantly polyploid and apomictic. It is also planted as a pasture under brizanyha crops and as a ground cover for erosion control.

Scientific name

Can tolerate frequent defoliation under grazing or cutting. Very responsive to fertiliser N, and may require repeated moderate applications. Oficial Methods of Analysis.

Biology, agronomy, and improvment. In the second cut, there was a quadratic effect due to the Si. The graphics were constructed using the SigmaPlot How to cite this article. Resistance to the spittlebug Deois flavopicta is probably from antinexosis, antibiosis and tolerance.

Silicon as an attenuator of salt stress in Brachiaria brizantha ‘MG5’

Good spread from seed in sown pastures. Growth pattern of creeping signalgrass Brachiaria humidicola Rendle Schweick in pasture fertilized with different nutrient sources. Grows on a wide range of soils with pH 4—8, textures ranging from light to heavy but free-draining and fertility from high to low, including those of acidic soils with high soluble Al concentrations. Identify the radiation protection principle. In plants under stress, the highest value for MM was obtained with 0 mmol L -1 Si.

With the increase in NaCl concentrations in the medium, there was a reduction in the increases of ADF, the minimum value being obtained with User Username Password Remember me. Alleviation of detrimental effects of NaCl by silicon nutrition in salt-sensitive and salt-tolerant genotypes of sugarcane Saccharum officinarum L.
