Water Content and Cost of Stratified Seed Related

Much of the weight of stratified seed consists of water absorbed during stratification. The Eastern Tree Seed Laboratory has determined the moisture content of 28 loblolly and 31 slash pine seed lots after standard 30-day wet-moss stratification. At the 5 percent level of confidence, the average moisture content, as determined by the ovendry weight method, was 29.34 t 0.71 and 38.58 t 1.86 percent for loblolly pine and slash pine, respectively. Moisture content percentages were 26.50 to 33.85 for loblolly and 33.13 to 53.46 for slash. Comparison of stratified slash pine seed lots with low (below 70 percent) and high (above 70 percent) germination showed that the moisture content of seed with low germinability was higher. A statistical analysis of the data showed one standard deviation from the mean to be 1.86 for loblolly and 5.07 for slash.
