How does the presence of endosperm affect seed size and germination?

Abstract: Endospermic seeds may germinate more successfully than non-endospermic seeds. The quantity of reserves of endosperm is directly related to seed size; large seeds may present faster and higher percentages of germination than small seeds. We investigate whether capacity and time of germination differ between seeds with and without endosperm in two species of Brassicaceae (Lepidium virginicum and Brassica rapa) and two species of Fabaceae (Crotalaria pumila and Medicago sativa). We also investigate whether seed s… Show more

“…Other functional seed traits may have an effect on germination; e.g., coat structure, shape, the presence or absence of spines, presence of endosperm, dispersal structures, tubercles or the presence or absence of mucilage (Harper et al 1970, Mott 1974, Valencia-Díaz et al 2015. Bu et al (2016), examining 383 Alpine meadow species, found a combined effect of shape and volume of seeds on germination, where the volume of the seed had an effect on the germination of elongated seeds.…”

“…En las tres especies se presentó mayor supervivencia en las plántulas que provenían de siembra en condiciones tradicionales. Al finalizar el monitoreo M. squamulosa presentó la mayor supervivencia general (laboratorio 23 %, tradicional 36,7 %), seguido por M. ligustrina que solo presentó plántulas vivas de condiciones tradicionales al de las semillas, esta leve diferencia se puede relacionar con la disponibilidad de recursos y nutrientes con los que cuenta la planta, el tamaño y su ciclo de vida, lo que ocasiona variaciones en el tamaño de las semillas incluso entre individuos de la misma especie, o semillas del mismo fruto (Westoby et al 2002, Valencia-Díaz et al 2015.…”

“…En general se presentó una alta viabilidad donde M. squamulossa fue la mayor y T. grossa la más baja, esto era de esperarse ya que las plantas que presentan semillas pequeñas se caracterizan por tener una estrategia reproductiva que consiste en producir una gran cantidad de semillas pequeñas, con baja probabilidades de establecimiento (Leishman et al 2000, Moles et al 2004, pero que al ser numerosas pueden aumentar la progenie en nuevos sitios (Valencia-Díaz et al 2015).…”

“…(CARDOSO et al, 2016;MISHRA et al, 2012;UCHIA, 2000;YANG, 2018). Os experimentos com as sementes ocultaram os impactos negativos da água residual, no metabolismo vegetal, porque essas estruturas possuem seu próprio tecido de reserva, denominado endosperma (SUDA et al, 2000;VALENCIA-DÍAZ, 2015;YAN et al, 2014) Desse modo, não há dependência nutritiva, em relação ao meio, para o desenvolvimento das plântulas (NONOGAKI, 2006).…”
