Popis:	1. Sterility of wheat plants caused by chilling injury could be distinguished more easily and exactly from sterility of any other descriptions, when overall tests are made, 4 to 5 days after flowering, as to such factors as shortness in internodes at spike necks, reopened glumes, abnormality of pollen, in addition to the primary factor, i. e., size and form of ovaries. 2. The sterile injury could be prevented to some extent by means of timely seeding, adop tion of low-temperature resistant varieties, and cultural practice for growing of healthy plants, but it is regarded as the most safe measure among othrs to culture 6-rowed barley in place of wheat crop, because 6-rowed barley is fairly great resistant to the chilling or frost injury.
