It was found that there was an increase in the number of seeds 
with an increase in the size of the cones, medium cones having 
27 per cent more seeds than the smaller ones, and the large cones

51 per cent more than the small cones. Another interesting thing 
was that there were more undeveloped seeds than developed, except 
in the case of the small cones, where there was a slight decrease. 
In the large cones 47.1 per cent of the seeds were fully developed,
