Dried samples were weighed with a Cahn electrobalance
, then ashed for 5 h at 500 [degrees]C.

method were 17% lower than values interpolated from data in this work (Fig.
Dry mass was measured using a Cahn electrobalance
([plus or minus] 0.
001 g and the gonadal tissue weighed (dry weight) on a Kahn electrobalance
Viable seeds from the same plant were pooled and seed mass per 25 seeds was measured on a Cahn electrobalance
Pulling the rhombic frame to an elongated shape reduced the surface tension of the DPPC film, and the surface tension force was measured by a platinum Wilhelmy plate connected to an electrobalance
Samples were then transferred to a Cahn RG electrobalance
enclosed in a glass vacuum system, maintained at the immersion temperature [+ or -]0.
Head-wings-thoraxes and abdomens were dried to constant weight at 60[degrees]C, weighed on an electrobalance
and, in some cases, also analyzed for total nitrogen by flash combustion on a Carlo Erba NA 1500.
After overnight desiccation, filter weights were determined using an electrobalance
(Model C-30; Thermo Cahn, Madison, WI).
Masses for each population in each environment were then determined using a Cahn electrobalance
Floral parts were separated, dried in a drying oven, and later weighed on a Cahn electrobalance
accurate to 0.
After sampling, we weighed the filters for total suspended particulate (TSP) analysis with an electrobalance
(model Cahn 21; Cahn Instrument Inc.
