THE use of the combine and the accompanying tendency to let the oat crop stand in the field after maturity has resulted in a peculiar type of lodging called stem-break. Stem-break is an "old age" form of lodging occurring after the plant is dead ripe. The use of a lodging resistance factor, cLr, as a measure of lodging resistance in the green plant was developed in a previous paper This paper on stem-break in senescence makes a natural sequence. Fortunately, resistance to this form of lodging is readily measured by letting the guard rows stand after harvest until the culms start to crinkle or break. Hence the problem is not so much one of measurement and prediction as one of determining the factors involved. The purpose of this paper is to determine some of the factors involved in stem-break in senescence and to find out if varieties resistant to lodging as measured by the cL,. factor tend to resist stem-break.
