The above table shows that soaking the seeds for periods exceeding 

 24 hours in general diminishes the rate of germination.

Pisum. The soaking of seeds of Pisum sativum previous to sowing has 

 a marked effect upon the subsequent course and vigour of development. 

 The number of plants produced is not affected by soaking the seeds for 

 periods of less than 24 hours. The retarding effect, however, upon the 

 subsequent growth shows itself in the case of the roots of plants produced 

 from seeds soaked even for the short period of 8 hours. After 48 hours 

 soaking of the seed it is very marked. The size of the shoots is not 

 greatly affected unless the period of soaking has exceeded 24 hours.
