| | How sucessful is fire, as a magament tool to control weeds in Australia? |
| | When germination is compared with mortality several trends are revealed, for example Gorse, has a mortality rate of 54% and an increase in germination of 79%, while Rubbervine has a 71% mortality rate and an 84% decrease in germination. | | | Therefore, the combination of enhanced germination and seed mortality can be attributable to increased temperature (Lonsdale and Miller 1993) the end result is a reduction in the number of dormant seeds in the seed pool. | | | The attributes used were, the effect of fire on existing plants; changes in the soil seedbank; changes in post fire germination, and; the temperatures associated with increased germination and outright mortality of seeds. |

| | Germination (root and shoot growth) occurred within 8 weeks in the seed held at 45F, 50F, and 55F, with the best results at 50 F. Western Americans are often described as exhibiting delayed hypogeal germination. | | | The temperature required for germination and formation of the small bulb varies with the type of lily, but a temperature of 60-70F generally works well. | | | Seeds exhibiting delayed hypogeal germination, such as martagons and orientals, form a small bulb during germination, and require a period at a lower temperature to break the shoot dormancy. |

| | Royal Botanic Gardens, Kew: Millennium Seed Bank Project: Seed Dormancy |
| | Seed dormancy has evolved in plants to ensure survival from the time of seed dispersal to the time of germination and seedling establishment. | | | First, when seeds do not germinate in routine germination monitoring at the MSB, this may lead to an underestimate of the true viability of the seed collection. | | | Seeds with physical dormancy are often chipped or covering structures are removed at the MSB to allow water uptake or remove chemical inhibitors or mechanical constraint and hence allow germination. |

| | 13th Crucifer Genetics Workshop |
| | Results and conclusions: Ascospores of both A-group and B-group L. maculans germinated on water agar and leaf surfaces at temperatures from 5°C to 20°C. Nevertheless, germination started later and % germination was less at 5°C than at 10-20°C. The maximum % germination on leaf surfaces was less than that on water agar. | | | To study infection, oilseed rape leaves were inoculated with A-group and B-group ascospore suspensions when plants were at growth stage 1,3 and ascospore germination and penetration of leaf surfaces were observed. | | | The % germination of ascospores, the lengths of germ tubes, the number of germ tubes per ascospores, the position of germ tubes and the diameter of germ tubes were observed. |

| | The goal of this research was to explore the relative importance of these sources in regulating achene (seed) germination and dormancy in White Snakeroot ( Ageratina altissima (L.) King and Robinson [ Eupatorium rugosum Houtt.]). | | | For instance, one plant (from a non-cold-requiring achene) produced achenes that exhibited 100% germination at room temperature, whereas another plant (from an achene that germinated after one cold treatment) exhibited 32%, 20%, and 16% germination after 0, 1, and 2 cold treatments, respectively. | | | In one population (even though the weight of large achenes was more than double the smallest) there were no statistically significant differences in cumulative germination between different size categories. |
