A study was carried out to test whether a single count of radicle emergence (RE test) would correlate with the storage potential seed lots cucurbit ( C. maxima × moschata ) rootstock cultivars. The RE performed by counting percentage between 26 and 100 hours germination. Seed longevity determined at 75% relative humidity 35°C over days, survival curves constructed based on normal germination pe...

BACKGROUND AND AIMS Olearia flocktoniae is an endangered shrub that was passively translocated from its natural ecosystem, where it has since gone extinct. This study aimed to determine sensitivities vital to populations persisting in human-created areas. METHODS Population colonization, longevity and extinction were investigated over 20 years using 133 populations. Seed-bank longevity was de...

Seed coating (‘seed treatment’) is the leading delivery method of neonicotinoid insecticides in major crops such as soybean, wheat, cotton and maize. However, this prophylactic use neonicotinoids widely discussed from standpoint environmental costs. Growing soybean plants neonicotinoid-coated seeds field, we demonstrate that aphids (Aphis glycines) survived treatment, excreted honeydew containi...
