Identification and Characterization of a Potyvirus Isolated from Siratro Plants

Journal of Phytopathology, 2008
AbstractThe present work describes the identification and characterization of a potyvirus isolated from siratro (Macroptilium atropurpureum Urb.) in the north‐west region of the State of São Paulo, Brazil. The virus was transmitted by mechanical inoculation. Its host range was restricted mainly to members of the Fabaceae.

Concentrations of Nutrient Elements in Parts of Siratro as Affected by Phosphorus Supply and Plant Age

Communications in Soil Science and Plant Analysis, 1976
Abstract The distribution of some nutrient elements in various parts of Siratro plants of different age and phosphorus status was examined in order to assess which plant parts were best to sample for chemical analysis of nutrient status and to estimate the relative mobility of these elements within the shoot. With increasing physiological age of leaves,

Effects of shade on some factors influencing nutritive quality of green panic and Siratro pastures

Australian Journal of Agricultural Research, 1982
The effect of illumination at 100, 60 and 40% sunlight over 4 months on herbage quality was studied in the legume, Siratro, and the grass, green panic, grown in small plots in the field in pure and 50 : 50 mixture swards, defoliated every 4 (D4) or 8 (D8) weeks.

Nodulation and Effective Nitrogen Fixation of Macroptilium atropurpureum (Siratro) by Burkholderia Tuberum, a Nodulating and Plant Growth Promoting Beta-Proteobacterium, Are Influenced by Environmental Factors [PDF]

Plant and Soil, 2013
Background and aims: Burkholderia tuberum STM678T was isolated from a South African legume, but did not renodulate this plant. Until a reliable host is found, studies on this and other interesting beta-rhizobia cannot advance. We investigated B.

Siratro Latent Polerovirus (SLPV): A New Polerovirus From Australia With a Non-Functional Open Reading Frame 0

Australasian Plant Pathology, 2019
Macroptilium atropurpureum (siratro) samples from Queensland, Australia were collected as part of virus surveys and screened using tissue blot immunoassays for the presence of luteoviridae viruses.

The use of epidermal hairs of the legume Siratro recovered in the faeces to estimate the proportion of Siratro in the diet of ruminants

Australian Journal of Experimental Agriculture, 1986
The epidermal hairs of the tropical pasture legume Macroptilium atropurpureum cv. Siratro number 3-5x 106/g DM; the hairs pass through the digestive tract of sheep and cattle undigested. A method for counting the hairs in Siratro samples and in faeces from animals which had consumed diets containing Siratro was developed.

Phosphate concentration in siratro as a guide to its phosphate status in the field

Australian Journal of Experimental Agriculture and Animal Husbandry, 1970
Siratro (Phaseolus atropurpureus) was grown under a range of soil and climatic conditions in sub-tropical Queensland, over the years 1964 to 1967. Phosphate concentration in the tops, sampled immediately prior to flowering, was poorly correlated with either the relative yield response to applied phosphorus, or the amount of phosphorus required to lift ...

Competition between siratro and kleingrass for15N labelled mineralized nitrogen

Plant and Soil, 1986
Isotope dilution provides a method for measuring plant competition for mineral N and transfer of biologically fixed N from a legume to a grass. A plant growth medium was enriched with15N, and used to grow Siratro (Macropitilium atropurpureum D.C. Urb.) and Kleingrass 75 (Panicum coloratum L.) in 20 liter pots for 98 days in a glasshouse.

Influence of Water Stress on Flowering and Seed Production of Macroptilium atropurpureum cv. Siratro

Annals of Botany, 1987
Macroptilium atropurpureum cv. Siratro was grown in large soil beds with a constant water table below, developing a dawn leaf watêr potential of --0.25 MPa. Water stresses equivalent to -0.7 or -1.0 MPa were developed over 14 d, causing reduced stem and bud elongation, leaf expansion, and bud differentiation and survival.

Nitrogen Fixing Activity of Water Stressed Siratro¹

Agronomy Journal, 1983
AbstractSiratro [Macroptilium atropurpureum (DC.) Urb. cv. siratro] is grown in tropical and subtropical environments characterized by frequent periods of drought and is dependent on N2 fixation for its N. These investigations were conducted to relate leaf and nodule water potentials to N2 (C2H2) fixing activity and determine the capability of nodules ...
