  2. Cold moist stratification

Evodia (Rutaceae). E. daniellii germ best when treated with GA-3, and the seedlings were normal and healthy. All other procedures gave long extended germinations in less than 1%. The GA-3 treatment was applied to seeds that had been 3 m at 40 (85% germ. in 1-6 w at 70), seeds that had been outdoor until April (85% germ. in 9-12 d), and seeds that had been DS for 6 m at 70 (55% germ. in 1-3 w). Even much lower dosages than those described in Chapter 3 were effective. The seeds were collected in November. The seed coats are in pairs with a larger viable seed and a smaller non-viable seed that soon rots.
