Germination of hulled and unhulled timothy seed, W. H. Bishop 



[iJelaivare Sta. B})!. ls9.5.,p. 340). — Gerniinator aud plat tests were made 

 of timothy seed to ascertain the eftect of the removal of the hulls from 

 the grain. In the germination apparatus the original sample gave 63 

 per cent vitality, while the hulled seed gave 56 aud the unhulled 72 

 per cent. Four samples of each were tested. In the plat trials no 

 difterence coukl be detected either in the germination or subsequent 

 crop. The slight depreciation in the germination of the hulled seed is 

 thought to be due to injury to the seed during threshing. 



Copper sulphate and germination, W. H. Evans ( U. S. Dept. A[/r., 

 Division of Vegetable rhysiology and Pathology Bui. 10., pp. 24). — A sum- 

 mary is given of numerous reports on the effect of solutions of copper 

 sulphate on various kinds of seed treated for the prevention of fungus 

 diseases. A detailed report is also given of experiments conducted by 

 the author in which is shown the eftect of different strengths of copper 

 sulphate solution on the germination of oats. Soaking seed for more 

 than 15 minutes in solutions of greater strength than 1 ])er cent was 

 found to retard and destroy germination to a considerable degree. 

 Experiments tended to show that previous soaking of seeds for a short 

 time in water prior to treating them with the fungicide would prevent 

 much of the injury arising from the use of even the stronger solutions-
