“…The notation for irradiated germ lines that were irradiated uses M codes such as "MDR" and "MSR" [7], However, the seed quality of these lines was never evaluated. In general, physiological qualities such as large seed size correlate with higher seed quality [8], [9], and [10].…”

Seed longevity could be described as a measure of seed viability after being stored for a certain period under particular conditions. Viability may vary due to genetic factors. The variations can be evaluated using physical and physiological quality traits such as seed weight, viability, and vigour. The results of such an evaluation are useful for future breeding efforts to enhance existing cultivars and develop new ones. We evaluated the physical and physiological traits of sixteen genetic lines randomly selected according to seed weight variations between mutated and non-mutated populations in UNPAD maize collections. The experimental design in this study was conducted using randomized completely design, with two replications. The data were analysed using analysis of variance and if data was significant then the post-hoc tested used Scott-Knott and Duncan at 5% level. Besides, we calculated the correlation between physical and physiological quality traits of seed. The results showed that the variation was exist in UNPAD maize collections. Furthermore, correlation analysis revealed that the positive and significant correlation between seed weight and synchrony of seed germination after 4 month storage. We suggested that seed weight was important traits for breeding program in maize to select good quality in associated to seed longevity.

“…In A. angustifolia seeds, starch is the carbohydrate most commonly found (ARALDI et al, 2016;SHIBATA et al, 2016), although soluble carbohydrates may be present. This compound act as a substrate for respiration during germination and may provide protection against the effects of desiccation (BERJAK et al, 2008;BONOME et al, 2011).…”

“…Araucaria angustifolia is an endangered (Brasil, 2008;Thomas, 2013) native Brazilian conifer tree. However, seeds from local varieties of A. angustifolia showed great diversity of physical and physiological parameters, which may reflect that a relevant genetic diversity is still present (Shibata, Coelho, Araldi, Adan, & Peroni, 2016;Araldi, Coelho, & Shibata, 2018). Its mature seeds are formed by a bulky megagametophyte, the major storage tissue, and an embryo, which represents only 1.3% of the total weight of the seed (Araldi & Coelho, 2015).…”

Germination metabolism of recalcitrant seeds of Araucaria angustifolia is activated in storage, which complicates the seeds conservation and utilization. This study aimed to identify the changes in the reserve metabolites of A. angustifolia seeds throughout storage in order to understand the processes of hydrolysis caused by germination metabolism. Mature seeds were harvested in southern Brazil and stored in an ambient environment and cold chamber conditions. Biochemical analyses were performed for embryos and megagametophytes from seeds stored for 0, 15, 30, 45, and 90 days. Due to seeds being in advanced germination in storage, they were evaluated at 90 days in different early developmental categories: I – seeds with mature embryos, II – seeds with embryos showing apparent elongation along the embryonic axis, and III – seeds with root protrusion. Higher contents of carbohydrate, protein, and amino acids were observed in embryos compared to megagametophytes, and these metabolites were decreased after onset of germination, especially in the embryo tissue. Mobilization of metabolites in megagametophytes would probably increase in later stages of germination. It is suggested that such alterations are not due to deterioration of reserve components, but instead are based on seed metabolism, which remains active after harvest with hydrolysis of metabolites providing energy for germination.
