SILVICULTURE, PROTECTION, AND EXTENSION 



Many years ago Hartig planted acorns of 

 Notes on the Querciis peduncitlata of different sizes and 

 Germination of studied the process of germination and early 

 Querciis Serrata growth of the seedlings. He concluded from his 

 experiments that the larger seed not only gave a 

 higher percentage of germination but, more important, that the seed- 

 lings were more vigorous and made a more rapid early growth. In 

 cases where the seedlings were adequately close those from the larger 

 seed ultimately overtopped the others and suppressed them. Rodger 

 has recently studied the germination and early growth of Quercus 

 serrata in India. In the autumn of 1916 a quantity of the seed of the 

 above species was collected and 200 of the larger and an equal number 

 of the smaller were sown in adjacent beds in good garden soil. A year 

 later all the seedlings in the two beds were rempved, counted, and 

 measured with the following results : 



Contrary to the conclusions of Hartig these experiments appear to 

 show that the size of the seed has little or no effect on germination and 

 early growth, and consequently upon the crop that may be expected 

 from the sowings. 



The writer realizing that the data obtained from his experiments are 

 too meagre for definite conclusions, suggests that similar data be col- 

 lected for various Indian species. Specific data on the effect of size 

 on the quality of seed are needed for American species. The necessary 

 data can be easily secured and the point should be definitely settled so 

 far as our economic species is concerned.
