EFFECTS OF AMPUTATION OF PRIMARY SEMINAL ROOTS ON SEEDLING GRASSES SEEDLINGS used in establishing spaced-planted grass nurseries are usually started in greenhouse flats. One method of starting these seedlings is to germinate seed in dishes and then transfer the seedlings to flats containing small paper plant bands. The primary seminal roots of grasses may sometimes reach a length of 40 to 50 mm. in 4 to 5 days after germination. The roots usually become tangled and the individual plants have to be separated. In addition to this difficulty, transplanting this unoriented, adhering root into a hole usually not more than 5/16 inch in diameter without excessive mutilation is time consuming. Considerable time could be saved if these roots could be removed before transplanting. Previous workhas indicated that the seedlings of many grass species depend on the primary seminal roots
