PLATE 36 



A. — Post-treatment seed injury occurring when wheat is dried after treatment 

 with a 0.1 per cent solution. Sample No. 1 was stored dry during the 28 days pre- 

 ceding this germination test, and sample No. 2 was stored damp in a sealed jar, the 

 latter germinating at the end of that time as v/ell as the untreated control. 



B. — Germinating seedlings of Little Club wheat, showing characteristic post- 

 treatment injury when seed is treated with a 0.1 per cent solution. The upper row 

 shows the usual deformity — curved, sickle-shaped plumule and prematurely broken 

 sheath. Below are seedlings from untreated seed, showing normal germination.
