Acquisition of freezing tolerance during the seed development of Pisum sativum L. cv. Akabana was studied in relation to changes in growth, dry matter accumulation, and water content. Seeds were cooled down rapidly by direct plunging into liquid nitrogen, so that below a determined water content, tissues could vitrify with the consequent survival of seeds. The proportion of seeds that were able...

The amount of liquid water in snow characterizes the wetness of a snowpack. Its temporal evolution plays an important role for wet-snow avalanche prediction, as well as the onset of meltwater release and water availability estimations within a river basin. However, it is still a challenge and a not yet satisfyingly solved issue to measure the liquid water content (LWC) in snow with conventional...

The eddy covariance method is considered the only direct flux measurement method. Its application for fog deposition measurements is relatively new and has a high potential to allow the accurate determination of nutrient and trace element deposition due to fog droplet interception by vegetation canopies. Based on experiences gained at an agricultural site on the Swiss Plateau and a mountainous ...
