Climatic, edaphic and altitudinal factors affecting yield and toxicity of Lathyrus sativus grown at five locations in Ethiopia.

Summary of "Climatic, edaphic and altitudinal factors affecting yield and toxicity of Lathyrus sativus grown at five locations in Ethiopia."

A two years (2005-2006) data analysis based on agronomic, qualitative, climatic and edaphic factors was carried out using ten grass pea (Lathyrus sativus L.) genotypes grown at five eco-divergent locations (Alem Tena, Debre Zeit, Denbi, Akaki, Chefe Donsa) in Ethiopia. Crop yield showed considerable variability among locations, years and genotypes. Path coefficient analysis indicated that rainfall and days to maturity have a large positive influence on yield. High level of micronutrients Mn(2+) and S(2-) negatively affected yield. Path analysis revealed that Zn(2+)/P, days to maturity, yield and K(+) were dominant variables affecting the response variable beta-ODAP (beta-N-oxalyl-L-alpha,beta-diaminopropionic acid), the neuro-excitatory amino acid in grass pea seeds considered as the cause of neurolathyrism. Linear correlation analysis between beta-ODAP and the 35 factors considered showed that beta-ODAP level was positively correlated (r > 0.70) with K(+) and sunshine hours (ssh) and negatively correlated (r < 0.70) with soil pH, days to maturity and yield. The strongest correlation of ssh with beta-ODAP level was found during the phase of crop maturity. Our results suggest that beta-ODAP biosynthesis and its response to environmental stress are maximized during the post-anthesis stage.

Medical and Biotech [MESH] Definitions

A multifactorial disease of CATTLE resulting from complex interactions between environmental factors, host factors, and pathogens. The environmental factors act as stressors adversely affecting the IMMUNE SYSTEM and other host defenses and enhancing transmission of infecting agents.

A genus of leguminous herbs or shrubs whose roots yield GLYCYRRHETINIC ACID and its derivatives, CARBENOXOLONE for example. Licorice toxicity is manifested as hypokalemia, low blood potassium. Licorice is used as flavoring and aromatic in pharmaceuticals and as candy.

A plant genus in the family FABACEAE known for LATHYRISM poisoning.

An autosomal recessive disorder affecting DIHYDROPYRIMIDINE DEHYDROGENASE and causing familial pyrimidinemia. It is characterized by thymine-uraciluria in homozygous deficient patients. Even a partial deficiency in the enzyme leaves individuals at risk for developing severe 5-FLUOROURACIL-associated toxicity.

Diseases characterized by inflammation involving multiple muscles. This may occur as an acute or chronic condition associated with medication toxicity (DRUG TOXICITY); CONNECTIVE TISSUE DISEASES; infections; malignant NEOPLASMS; and other disorders. The term polymyositis is frequently used to refer to a specific clinical entity characterized by subacute or slowly progressing symmetrical weakness primarily affecting the proximal limb and trunk muscles. The illness may occur at any age, but is most frequent in the fourth to sixth decade of life. Weakness of pharyngeal and laryngeal muscles, interstitial lung disease, and inflammation of the myocardium may also occur. Muscle biopsy reveals widespread destruction of segments of muscle fibers and an inflammatory cellular response. (Adams et al., Principles of Neurology, 6th ed, pp1404-9)
