Overview

Excerpt from Proceedings of the Second Annual Meeting of the Western Canadian Society of Agronomy: Held in Winnipeg Dec; 27, 28, 29, 1921 The question we are asking ourselves is whether or not the bell jar gives a fair test. As some of you may not have seen the bell jar method, which, by the way, was introduced in Calgary by Mr. Fryer, we have prepared a small chart. You will see that the apparatus is quite simple, consisting of two disks of blotting paper (one of which is provided with a blotting paper wick), a cup, and a bell jar. The cup is nearly filled with water and covered with a blotter provided with a wick - the latter, of course, being in the water. The second disk is placed on top of the first, and on this the timothy seed is sprinkled, the whole being covered with the bell jar. In this method the timothy receives much more moisture than when planted in the soil or between blotters unconnected with moisture pan. A film of water can be seen on the surface of the upper blotter, whereas when the timothy is planted in soil in a small cardboard box, which has holes punctured in the bottom, and which stands on blotters, there can be no chance of excess moisture accumulating. Which method will give us the best idea of the true germination value of the seed under natural conditions is the problem which yet remains to be solved. As far as we can see, the only way is to grow the seed in the open. The great difficulty is to be sure that there is no grass seed already in the soil of the plot. This brings up the difficulty of soil sterilization, and it is this point which we would like discussed at this meeting, and we can assure you that any suggestions will be very very thankfully received. Once this obstacle is overcome there is no doubt that the field tests of grasses will give very valuable information as to the actual value of laboratory tests, and so decide which test can be adopted as the standard method for each variety of grass.
