| Abstract/Contents: | Emergence of Veronica hederifolia sedlings began in mid-October and continued into spring; few appeared from June to September. Ripe seeds shed in June were dormant but when buried in soil outdoors developed a capacity for germination initially at low temperatures (constant 4 degrees C; daily alternations of 4-10 degrees and 4-15 degrees C) and later at somewhat higher temperatures, with peak germination in September-November. During winter, spring and early summer the germination capacity declined, to increase again in late summer and early autumn. Cyclic physiological changes thus occur in seeds of Veronica hederifolia present in the soil, with which the consistent seasonal periodicity of seedling emergence is associated. In dry storage the capacity for germination progressively increased, but after 12 months there was a sharp decline in germination at 4 degrees C. Few seeds germinated at 20 degrees C, but moistening with GA4/7 brought about complete germination at this temperature. |
