Determination of Chlorophyll Concentration in In Vitro Peanut Leaves
(Wiley, 2025-05)The detection of chlorophyll is a convenient method for assessing gene editing efficiency when generating mutations in the phytoene desaturase (PDS) gene, which is related to chlorophyll biosynthesis. Various instruments ... -
Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids
(Wiley; Scandinavian Plant Physiology Society, 2016-08)Sweet sorghum has a photosynthetic system which is highly sensitive to cold stress and hence strongly limits its development in temperate environments; therefore, the identification of key exploitable cold tolerance traits ... -
Differential response of Trichloris ecotypes from different habitats to drought and salt stress
(Springer, 2020-08-05)Native plant genetic resources have evolved from long processes of natural selection and adaptation to specific environments, and have developed tolerance to various stresses prevailing in their natural habitats via adaptive ... -
Differential salt-stress response during germination and vegetative growth in in vitro selected somaclonal mutants of Cenchrus ciliaris L.
(2013-07)Four somaclonal mutants (S1, S4, S6 and M10) and their parental Cenchrus ciliaris L. cultivar Biloela were characterized under salinity conditions at germination and vegetative growth stages. Seeds of all somaclonal mutants ... -
Dinámica de la generación de desperdicios vegetales en mercados concentradores frutihortícolas del área metropolitana de Buenos Aires (AMBA)
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2023-06-26)En Argentina, donde 16,7 millones de personas padecen inseguridad alimentaria, se reportan pérdidas y desperdicios de más de 16 millones de toneladas al año, siendo las frutas y verduras los alimentos de mayor proporción. ... -
