METHODS OF HASTENING GERMINATION 



By S. B. Show

In the spring of 1913 the Feather River Experiment Station made a 

 number of tests with hastening germination. The technique of the work 

 was faulty, in that the germination period was only 90 days, only 100 

 seed were used in each test, and incomplete records were kept. This 

 study was later dropped because fall sowing has solved the problem of 

 slow germination of sugar pine. It may occasionally happen, however, 

 that, on account of early snow, fall sowing is impossible, and in such 

 cases the results of the tests at least indicate the methods of treatment 

 which promise success. Similar tests were made at Pilgrim Creek, in 

 191 1, but the results have never been made available. 



The following tables summarize the results of the tests carried on by 

 the Feather River Station. These are not regarded as conclusive, and 

 are given here merely as suggestive of the tendency. They do indicate, 

 however, that soaking in solutions of sulphuric acid gives the best re- 

 sults for sugar pine.
