Chionodoxa (Liliaceae). C. luciliae self sows abundantly here and seed was plentiful. Seed was collected in three succesive years. The three consistent resultswere (a) all DS seed rotted (DS is fatal), (b) seed WC for a week to remove the aril germ. much better than unwashed seed, and (c) the cycles at 40 should be extended to 4-5 m instead of the usual 3 m. Seed collected in May 1989 and WC germ. 70-40(50% in 12-16 w)-70-40-70(15%). The first 40 cycle was extended to 16 w as evident from the data, and the last 15% that germ. at 70 would probably have germ. in the preceding 40 cycle if it had been extended beyond 4 m. Unwashed seed germ. 70-40-70(7%)-40(10%), but the cycles at 40 should have been extended beyond 3 m, and the experiments need repeating. The 1989 and 1988 collections should have been given outdoOr treatment because the 1990 seed germ. 22% in March in outdoor treatment. Cotyledons developed normally only lithe seedlings Were left for 1-2 m at 40 after germination before the shift to 70.
