possible that the lack of pollen may partly account for the damage 

 done by mould. 



2. The effect of pollination in gardens where the hops do not 

 usually grow out well. 



3. The influence of temperature and moisture on the libera- 

 tion of pollen and the spread of mould. Generally speaking, damp,, 

 cold weather favours mould and also checks the liberation of 

 pollen. 



4. The possible relation between the percentage of seed and 

 the total crop. Fertilisation seems to stimulate the growing out of 

 *he hop, and its absence has the reverse effect. 



5. The comparison of the brewing value of seedless and seed 

 hops. The determination of the total resins seems to be the best 

 way of arriving at an opinion on this point. 



6. Comparative infection experiments with mould on seed and 

 seedless hops. 



7. The influence of pollen from different males on the 

 development of particular varieties. 



8. The effect of various washes on hops when in burr. Possibly 

 fertilisation may be interfered with or even prevented when hops 

 are sprayed at this stage. 



9. The influence of seed formation on the " thickness " of the 

 sample as taken from the pocket. 



10. The effect of fertilisation on the compactness or " density " 

 of the hop. 



1 1 . The effect of premature pollination on the development of 

 the hop. 



12. The selection of seedling and foreign male plants to suit 

 the time of flowering of the various Kentish varieties. 



As far as possible these lines of enquiry will be followed ur> 

 during the coming year.
