Variación en la producción de alcaloides en inflorescencias de Senecio Grisebachii por deficiencia de nutrientes Alkaloid production changes due to nutrient deficiencies in Senecio Grisebachii inflorescences
Autor: Margarita A Yaber Grass, Marina Ciancia, Silvia R Leicach
Publikováno v: Ciencia del Suelo, Vol 27, Iss 1, Pp 31-39 (2009)
Senecio grisebachii Baker es una maleza que invade pasturas naturales y cultivos en el sur de Brasil, Uruguay, y provincias mesopotámicas y Buenos Aires en la Argentina y es considerada tóxica debido a la presencia de alcaloides pirrolizidínicos (

Changes inSenecio grisebachiipyrrolizidine alkaloids abundances and profiles as response to soil quality
Autor: Silvia R. Leicach, Margarita Yaber Grass
Publikováno v: Journal of Plant Interactions. 7:175-182
Senecio grisebachii Baker is an invasive weed considered to be toxic due to the presence of pyrrolizidine alkaloids (PA) in its tissues. The PA production by S. grisebachii aerial parts was evaluated in samples grown in two Argentinean Rolling Pampa

Publikováno v: Journal of Plant Interactions. 5:205-210
Water deficit, a common constraint in forestry, is the main cause of plant stress during plantation. The survival and growth of seedlings is also compromised by herbivory during establishment. The potential of nursery preconditioning to enhance survi

Changes in Lupinus albus and Lupinus angustifolius Alkaloid Profiles in Response to Mechanical Damage
Autor: Silvia R. Leicach, Hugo Daniel Chludil, María del Pilar Vilariño, María Luz Franco
Publikováno v: Journal of Agricultural and Food Chemistry. 57:6107-6113
The aim of this work was to evaluate chemical responses to biomass removal mimicking large herbivore action in Lupinus albus and Lupinus angustifolius aerial parts. GC and GC-MS were used to determine total alkaloid content (TAC) and alkaloid relativ

The confused flour beetle, Tribolium confusum Jaquelin Du Val, 1868, is a common pest insect known for attacking and infesting stored flour and grain. Biodegradable and ecologically natural products such as essential oils are emerging candidates for

Post-damage alkaloid concentration in sweet and bitter lupin varieties and its effect on subsequent herbivory
Autor: Silvia R. Leicach, M. del Pilar Vilariño, G. Mareggiani, Damián A. Ravetta, M. Y. Grass
Publikováno v: Journal of Applied Entomology. 129:233-238
While most lupin species possess quinolizidine alkaloids, sweet (low alkaloid) varieties are more palatable but at the same time more susceptible to herbivory. Nevertheless, as they are not totally devoid of alkaloids, it may be possible that their a
