Illuminating Long-lived Cycas Cotyledons Reduces Sink Demands on Megagametophytes during Initial Seedling Growth

open access: yesHortScience
Cycas megagametophyte resources are translocated to developing seedlings through the persistent green cotyledons. The source activities of cotyledons and megagametophytes following germination are not adequately understood. The decline in megagametophyte

Long-term analysis of clear-sky new particle formation events and nonevents in Hyytiälä [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
New particle formation (NPF) events have been observed all around the world and are known to be a major source of atmospheric aerosol particles. Here we combine 20 years of observations in a boreal forest at the SMEAR II station (Station for Measuring ...
