 FIELD CROPS 



PRACTICUM NO. 1 . 



Object. To Study the Seedling Characteristics of Some of the 

 More Common Plants. 



Materials. Sand, box 12" by 12" by 3", germination dishes, 

 blotting paper. 



Plant several seeds each of wheat, corn, peas, beans, in 

 moist sand in the box and set in a warm place; keep the 

 sand moist and watch the development as soon as the first 

 sprouts appear above the ground. 



Notice which bring part of the seed above the ground with 

 them. 



Method. Without injury to the young plant, clip off the 

 greater part of the two halves of some of the beans and com- 

 pare the development of plants thus treated with those which 

 are allowed to grow normally. 



Place a dozen kernels of wheat between wet blotters which 

 have been cut to fit the inside of a pie plate; invert another 

 pie plate over the first and set this germinator in a warm place 

 for a few days, taking care that the paper remains moist. 



Place several seeds in a similar germinator, which has been 

 made in a large-necked bottle. Cork the bottle and immerse
