up to a certain point. The seeds ■will 

 develop and give a noimal sprout, if 

 given time enough and a higher tem- 

 perature. In this respect they differ 

 from lettuce seeds, for instance. Let- 

 tuce, too, shows a transitional period 

 before complete loss of vitality, but 

 the sprouts that i)ush out are abnormal 

 and cannot be considered able to pro- 

 duce a plant. 



These iirobloms need experimental 

 work, and in time may work out more 

 satisfactorily. They might be partially 

 solved by better harvesting methods, 

 but jirobably the most could be done by 

 correct storage. 



Closely allied to the dormancy proli- 

 lem is that of localized dormancy — tlic 

 dormancy of certain parts of the seed. 

 This is probably not a true dormancy, 

 but rather a complete inhibition of the 

 normal development of one or more of 

 the parts of the seed; for instance, 

 the inhibition of growth in the radical 

 or tap root often found in corn. Such 

 a sprout, if left in the gorminator, will 

 often send out lateral roots, often 

 strong-looking lateral roots, but will 

 never send out the radical. Whether 

 this inhibition has an internal or ex- 

 ternal cause has not been determined. 

 The question then is, will these lateral 

 roots have a strong enough development 

 to make a good plant? The cliaiu-es are 

 it will make a i)lant of some kind and 

 possibly a ]>lant which might do well 

 under favorable conditions, but one 

 which would have little chance under 

 adverse i-onditions. Many of these 

 cases are probably pathological. Safe- 

 guarding, then, in a commercial labora- 

 tory, would be to count these sprouts 

 sparingly, if at all; for we must aim to 

 have seeds that will give a good stand, 

 not only in the early stages of devel- 

 opment, but also in the mature stages 

 as well, and not die or dwarf when par- 

 tially grown. 



Variations in Sprouting. 



At this point it miglit be well to 

 mention the growing importance of the 

 identification of plant diseases in the 

 seed and seedling stages. There is a 

 great deal a seed analyst can do in a 

 commercial laboratory in addition to 

 straight germination. It is something 

 the analyst will have to prepare to 

 meet in the near future. 



This opens up the important question 

 of bad sprouts. Here we have the 

 cause of some of the variations in ger- 

 mination tests which one gets in check- 

 ing up with different laboratories. Good 

 seeds are not considered, of course, as 

 they will not have a variation in 

 sprouts. It only applies to seeds on the 

 border line. "When seeds begin to lose 

 their vitality the intermediate stages 

 of deterioration are ])resent. The 

 sprouts will not be normal; neither will 

 they be altogether bad. The official 

 analysts say at this point: "Do not use 

 seeds on the border line," which is all 

 right on carry-over stock. If the seeds 

 are bad and a cleaning does not help 

 their condition, those seeds cannot be 

 sold. Wlien such seeds have been re- 

 ceived on an order or contract, how- 

 ever, we must guard against taking in 

 stock that has l)egun to deteriorate, 

 and it is in such cases where tlie varia- 

 tion in personal judgment becomes im- 

 portant. It is a question of germina- 

 tion versus viability. 



The causes of abnormal sprouts are 

 both internal and external. The internal
