It has been shown that the adverse effects of salinity can vary between different varieties of the same plant species. This study was conducted to determine the tolerability of three newly released lines of maize to saline conditions when primed with ethylene diamine tetraacetic acid (EDTA) and salicylic acid (SA) each at 1.0 M concentration; seeds primed with distilled water were used as control. Concentrations of 0, 50, 100, 150 and 300 mM NaCl were tested. The experiment followed a 3x3x5 factorial arrangement of treatments with three replications. The results revealed significant interaction between maize lines and salinity where the germination percentage of line SWAN-LSR-Y was much more affected than the other lines at the salinity level of 50 mM, and its speed of germination was more affected than the others when passing from 150 to 300 mM NaCl. The seedling lengths (radicle and plumule) and seed vigor index were influenced by significant interaction between the primer and salinity, where EDTA enhanced better seedling growth than the other primers when the salinity did not exceed 150 mM. OMR-LSR-SY maize line did not show tolerability at this concentration. Similarly, EDTA and SA treated maize lines showed lower accumulation of reactive oxygen species such as superoxide anion radical (O2-), hydrogen peroxide (H2O2), as well as a decrease in the malondialdehyde (MDA) contents, most importantly in SWAN-LSR-Y and BR9928-OMR-SR-Y maize lines. Catalase (CAT) and superoxide dismutase (SOD) activities were enhanced in SWAN-LSR- Y and BR9928-OMR-SR-Y upon application of EDTA.

“…The germination proportion of C. hololeuca seeds defecated by the captive marmosets were compared to that of non‐ingested seeds by a t ‐test in the r package Stats . We also compared the germination rate between treatments (ingested × non‐ingested seeds) using the Germination Rate Index (GRI) proposed by Maguire (1962) and revised by Pire and Vargas‐Simón (2019). The GRI values of each treatment were further compared by a t ‐test in the r package Stats .…”

1. Dispersal limitation severely impairs the trajectory of restoration, mainly due to the lack of seed vectors bringing seeds from nearby habitats; a role played by many frugivorous vertebrates that can be absent or reduced in restored or degraded sites. 2. Here we propose a new technique named Induced Seed Dispersal, that amplifies the role that many generalist frugivores have in seed dispersal. It consists in the offering of seeds embedded in the pulp of commercial fruits or whole native fleshy fruits in feeders to generalist frugivores, which ingest the seeds and defecate them elsewhere. We set feeders in a restored site and monitored the visiting pattern of these frugivores with cameras-traps. We also set seed traps to retrieve seeds dispersed by frugivores and offered around 1,500 seeds of Cecropia hololeuca (Urticaceae) per week for 1 year. 3. We recorded at least 24 generalist frugivore species of terrestrial mammals, bats and birds, which ingested/removed the seeds/fruits from the feeders. Seeds of C. hololeuca dispersed by marmosets were retrieved in the seed traps and germinated. We estimated a potential seed rain of more than 600 C. hololeuca seeds ha −1 mo −1. 4. Synthesis and applications. Our study demonstrates that this new technique can make use of generalist frugivores to assist restoration or regeneration into sites where seed dispersal is compromised by the lack of dispersers or limited seed arrival. Inducing seed dispersal by generalist frugivores is a low-cost and easymanaged technique that can be applied year-round in restoration and forest enrichments at all scales.

“…El diseño experimental de la germinación fue completamente aleatorio de seis tratamientos y cinco repeticiones por tratamiento de seis semillas como unidad experimental. Se calcularon: porcentaje de germinación (PG) y tasa de germinación (TG); el primero se obtuvo con la relación porcentual de semillas germinadas luego de 37 días; para el cálculo de la TG se sumaron los cocientes de los porcentajes de germinación y su respectivo día de evaluación con base en la fórmula de Maguire (1962), ajustada por Pire y Vargas-Simón (2019). Se realizó un análisis de varianza luego de comprobar los supuestos de normalidad y homocedasticidad; y prueba de medias de Tukey utilizando el programa Statistix 8.0 (2005).…”

Annona reticulata es una especie nativa del Neotrópico, poco domesticada, común en huertos familiares y su fruto es de sabor agradable. Como una estrategia de conservación del germoplasma, y considerando que determinados tratamientos pregerminativos pueden favorecer su capacidad de germinación, se plantearon dos objetivos: la caracterización morfológica de frutos y semillas, y el estudio de la respuesta a varios tratamientos pregerminativos. Las muestras provienen de Tabasco, México. Se midieron frutos y semillas. Las semillas se sometieron a seis tratamientos pregerminativos: Testigo (T1), escarificación mecánica (T2), remojo en ácido giberélico (AG3 100 mg L-1 por 3 h) (T3), remojo en AG3 (100 mg L-1 por 6 h) (T4), remojo en AG3 a 200 mg L-1 por 3 h (T5), y escarificación mecánica + remojo en AG3 (100 mg L-1 por 24 h) (T6). Se determinó el porcentaje total de germinación (PG) y la tasa de germinación (TG) en un ensayo completamente al azar con cinco repeticiones. El peso promedio del fruto fue de 422,2 g, con 113,8 semillas, de los cuales el 69,22 % estuvo representado por el peso de la pulpa. La germinación criptocotilar epígea inició el día 17 y alcanzó su máximo (76,6 %) el día 31. La escarificación mecánica (T2) promovió los mayores valores de PG y TG, mientras que el uso del AG3 afectó la germinación y produjo los menores valores a medida que se incrementaron las concentraciones y tiempos de remojo del producto.
