lings from the substratum and reread the fluorescence at the time of the final count. (11) Trifolium, Medicago, Melilotus, and Vicia faba; temperature requirements. A temperature of 18° C. is desirable for Trifolium spp., Medicago spp., Melilotus spp., and Vicia faba. (12) Garden beans (Phaseolus vulgaris); use of calcium nitrate. If hypocotyl collar rot is observed on seedlings, the sample involved may be re tested using a 0.3 to 0.6 percent solution of calcium nitrate to moisten the germination medium. (13) Fourwing Saltbush (Atriplex canescens); preparation of seed for test. De-wing seeds and soak for 2 hours in 3 liters of water after which rinse with approximately 3 liters of distilled water. Remove excess water, air dry for 7 days at room temperature, then test for germination as indicated in Table 2. (c) Table 2; germination requirements for indicated kinds.
