The three proposals embodied in Dr. von Degen's Report were 

 unanimously agreed to by the Congress. 



Professor Johannsen proposed, and the Congress unanimously 

 agreed, that Messrs. Brown, Devoto and KuleschofE should be 

 appointed additional members of the Dodder Committee. He 

 intimated that it was not essential that these three gentlemen 

 should travel to meetings of the Committee, but that they might 

 act as consulting members. 



The business for the day having concluded, the Delegates 

 then travelled to St. Ives in order to inspect Sir Fred Hiam's 

 farm, where some fine wheat, especially Professor Biffen's 

 " Yeoman II " Wheat, is grown. 



Wednesday, 9th July. 



Morning Session^ 



The Congregg .assembled at 10 a.m. 



Professor Vdigt read a paper on " Germination methods," a 

 summary of which is given below. 



English Summary. 



Since our meeting at Copenhagen in 1921 remarkable work has been 

 done concerning the physiology of the germination of seeds, especially on 

 chemical and physico-chemical influences retarding or accelerating germi- 

 nation. Mr. Popoff has carried out experiments on similar lines and has 

 had good results in getting higher yield from grain by soaking it in MgCl,; 

 similar results have also been obtained by the use of the fungicides 

 Germisan and Uspulun. 



Nevertheless I am of opinion that it is not yet time to introduce these 

 matters into practical seed testing. It is necessary to study the whole 

 material for a longer time. 



The two enquiries made under the direction of the Copenhagen Station 

 have given, for the main stations, such consistent results that it does not 

 seem useful to change the methods to-day. 



On the other hand good work has been done on special questions by 

 Ziirich in collaboration with Hohenheim (Pinus Strobus), Copenhagen 

 (Pinus Strobus), Hamburg (Anthoxanthum Pu61ii, Festuca ovina, Aira 

 flexuosa, Cynosurus oristatus) and others, which are directly useful for 

 practical seed testing.

Professor Voigt submitted for discussion and adoption the 

 " General Directions for Germinating Tests " which he proposed 

 at the Copenhagen Congress in 1921.* 



After a prolonged discussion Professor Johannsen intimated 

 that aU outstanding, matters connected with these " Directions " 

 would be dealt with by the appropriate Committee of the 

 Association to be appointed on Thursday afternoon.
