The Asteraceae with up to 30,000 species occurs on all continents except Antarctica and in
all major vegetation zones on earth. Our primary aim was to consider cypselae dormancy …

We studied the variability of germination, dormancy and viability loss of Hirschfeldia incana
seeds in relation to seed size. Seeds were stored at 35° C under humid [75% relative …

Statistical significance, or lack thereof, is often erroneously interpreted as a measure of the
magnitude of effects, correlations between variables or practical relevance of research …

Survival during burial is dependent upon a seed's ability to resist pathogen pressure and
physiological aging. Several studies support a positive interspecific relationship between …

Recent evidence points to relationships between intra-specific seed mass variation and
viability loss in response to ageing stress. However, little is known about how seed quality …

Asclepias humistrata (sandhill milkweed) is a forb native to the Southern Coastal Plain of the
USA, with potential use in restoration projects as a monarch butterfly larval host and as a low …

Studies on seed science are developed for a wide range of purposes, being the statistical
analysis of data essential for experimental reliability and evidence. Due to the characteristics …
