这种植物可由种子繁殖。
这些寿命极短的植物大量繁殖；也就是说，它们在母株周围持续提供着“种子雨”。
These very short-lived plants reproduce prolifically; that is to say they provide a constant rain of seed in the neighborhood of parent plants.
如果种子落在了合适的栖息地，它们就会生长得很好并进行繁殖。
If the seeds land in a suitable habitat, they do well and reproduce.
显然，仅依靠种子生存或传播的植物物种更容易受到植物繁殖力下降的影响。
Plant species dependent solely on seeds for survival or dispersal are obviously more vulnerable to any decrease in plant fecundity that occurs.
为了繁殖，植物必须将种子传播到其他地区。
In order for plants to reproduce, they have to spread their seeds to other areas.
为了繁殖，植物必须将种子传播到其他地区。
In order for plants to reproduce, they have to spread their seeds to other areas.
