Effects of seed water content and storage temperature on the germination parameters of white spruce, black spruce and lodgepole pine seed

Storage time affects the germination and proteomic profile of seeds of Cariniana legalis (Mart.) O. Kuntze (Lecythidaceae), an endangered tree species native to the Brazilian Atlantic Forest

“…The observed reductions in moisture content and seed germination percentage during storage in this study could be associated with the low tolerance to seed desiccation in this species (Sousa et al 2016). Low desiccation tolerance has also been reported in other species (Beardmore et al 2008;Marques et al 2014;Dias et al 2016;Sena et al 2016). The proteomic analysis revealed differences in the abundances of proteins in several classes among the different times of storage, and we discuss our results in the context of the functional classifications of these differentially abundant proteins.…”

“…Moreover, seed longevity is affected by storage conditions, including temperature and humidity (Sathish et al 2015). During seed storage, the temperature and seed moisture content are two important factors that affect seed viability and germination (Beardmore et al 2008). Greater deterioration occurs in seeds with a higher moisture content, thus affecting the longevity and seed survival, and moisture contents of 6-8% represent the optimum condition to maintain maximum longevity and vigor (Jyoti and Malik 2013).…”

Thermodynamics of Seed and Plant Growth

“…The main characteristic of seed is low water content, which could vary depending on plant species, environment and seed condition (Beardmore et al, 2008;Siddiqui et al, 2008). Seed water consists of two components, bound and bulk water (Krishnan et al, 2004c).…”

“…From the point of glass stability, water and temperature play significant roles in determining the storage longevity of orthodox seeds. Some models have demonstrated that the effects of water and temperature on seed aging are interdependent (Beardmore et al, 2008), indicating desiccation as the main contributor to loss of seed viability. On the other hand, Walters et al (2001;2010) considered that seed ageing, as the main result of free radical production, is the most important factor for viability loss.…”

“…The time curve of water absorption has a sigmoid shape (Beardmore et al, 2008;Siddiqui et al, 2008). The rapid entrance of water by the laws of diffusion and osmosis, present during phase I of imbibition ( Fig.…”
