Abstract
A TOPOGRAPHICAL chemical test for germination was devised by Lakon1 using sodium biselenite, which, on account of its toxicity, he rejected in favour of the tetrazolium salts2. Later, he evolved a technique for maize3 with 2,3,5-triphenyl tetrazolium chloride, which was used in Germany during the War4. As information about other cereals was inadequate, a preliminary assessment of this compound as a germination indicator has now been made.
