Herbicide resistance is an evolutionary process that may involve changes in physiological and ecological traits related to plant fitness. This type of occurs littleseed canarygrass ( Phalaris minor ). study was aimed determine the effect ACCase-inhibiting herbicides on fitness seed accessions canarygrass. Seed characteristics are important because they outcome competition between susceptible (S) resistant (R) biotypes. Experiments were performed whether differences S R embryo size, dormancy,...
Background: Herbicide application to control weeds can promote a rapid selection of resistant phenotypes in small geographic areas. Also, areas with spatial heterogeneous management, resistance may evolve independently, promoting local adaptation weeds. In the Mexican region known as “El Bajio,” 100,000 ha are cultivated wheat, and weed Phalaris minor , ACCase-inhibiting herbicides is present common.Question: We aim identify population structure two genes four different P. biotypes from...
Herbicide resistance has the potential to impose fitness costs in plants. In Mexico, Phalaris minor Retz. evolved acetyl‐coa carboxylase (ACCase) inhibiting herbicides. However, it is unknown whether these changes may involve other ecological for resistant individuals under non‐selective conditions. The aim of this study was determine evolution reduced ability P. compete resources at seedling stage. De Wit's replacement series experiments (susceptible:resistant 100:0, 50:50, 0:100) were...
This study was conducted to evaluate the influence of fruit maturity and postharvest storage on physiological qualities chili seeds during development. Two types were used (ancho guajillo). Fruits harvested at 40, 60, 80, 100, 120 140 days after anthesis (daa) stored for 0, 7 14 harvest (dah). The moisture content guajillo throughout development decreased from 86 17%, while ancho maintained 47% 80 dda. It confirmed that precocious (40 daa) not beneficial quality seeds, even when it...
Background. Physical dormancy in seeds of the genus Lupinus restricts their ecological or agricultural use. Hypothesis. This can be broken when are subjected to physical and chemical pretreatments that increase germination, mobilize reserves decrease ABA. Studied species. Seeds exaltatus (Le), L. campestris (Lc) montanus (Lm) from Puebla, México. Methods. The following seven treatments, including a control, were applied: PG1 = 98 % H2SO4 for 15 min, PG2 wet sand at 80 °C 5 PG3 35 8 h 16 25...
La resina de Liquidambar styraciflua (Altingiaceae) fue colectada en temporada sequía y lluvia durante 2013, las comunidades Santa Lucía, Tianguistengo, Xochimilco Xalapa el estado Hidalgo, México. El aceite esencial la se obtuvo por hidrodestilación. mejor rendimiento con 9.3 %, época sequía. analizaron cromatografía capa fina gases acoplada a espectrometría masas, respectivamente. análisis mostró mayor número compuestos Se calculó relación frentes ambas temporadas, algunos valores...
Las variaciones climáticas y la presión constante ejercida por el ser humano sobre los recursos naturales aumento continuo de población mundial, han hecho que actores las actividades agrícolas enfrenten desafíos en búsqueda alternativas para asegurar productividad cultivos.
La fertilización en vivero es una práctica cultural con potencial para mejorar la calidad de planta, pero necesario definir niveles adecuados cada especie. Este estudio evaluó el efecto planta Pithecellobium dulce, durante etapa vivero. Los aplicados fueron nueve; consistieron regímenes los que se combinó un fertilizante liberación controlada (FLC) 18-6-12, tres dosis (4 g L-1, 6 L-1 y 8 sustrato) hidrosoluble (FHS) 20-20-20, concentraciones nitrógeno 0 mg 75 150 L-1. El determinó analizando...
Las prácticas culturales de vivero tienen como objetivo mejorar la calidad las plantas e incrementar supervivencia reforestaciones; sin embargo, para cada especie debe examinarse el efecto diversas definir su factibilidad implementación. Este estudio analiza poda aérea en morfológica Caesalpinea coriaria determinar potencial práctica cultural. En condiciones invernadero, se evaluaron tres niveles poda: 0 %, 25 % y 50 %. El podas examinó seis meses por medio atributos índices morfológicos...

 En México el frijol (Phaseolus vulgaris L.) es una semilla leguminosa de elevado consumo (11 kg per cápita anualmente), por lo que su cultivo amplio en diferentes regiones. este estudió se determinó la presencia aflatoxinas ocho variedades común y cinco mejorado; además del contenido proteína humedad. todas las evaluadas humedad mostró grandes variaciones (6 a 16%), encontrándose 16% estudiadas fuera normatividad (<12%). El mayor detectó mejoradas (26.1%) más bajo...
Understanding the responses that some plants exhibit to acclimatize and thrive in different light environments can serve as a guideline optimize their production or establishment. Morpho-physiological changes Crescentia alata Enterolobium cyclocarpum were examined response varying levels: 25%, 35%, 55% 70% of photosynthetic photon flux density (PPFD) total solar radiation. One-month-old seedlings subjected treatments; subsequently, effects on morphology, capacity, nutrient status,...
