Effect of warm and cold stratification, and ethanol treatment on germination of Corylopsis seeds

open access: yesHorticultural Science, 2016
Seed germination experiments with Corylopsis coreana, C. sinensis var. calvescens, and Corylopsis gotoana were conducted. Corylopsis coreana seeds were treated at 5o, 7.5o, 10o, 12.5o and 20oC to study the upper temperature limit to break dormancy. Seeds

Optimum reaction conditions for the synthesis of macromonomers via the high-temperature polymerization of acrylates

open access: yes, 2009
Macromonomers are valuable synthetic building blocks: They can be copolymerized with low molecular weight monomers to generate brush-like structures or serve as conjugation substrates in pericylic, metathesis, and thiolene reactions.
