研究了兼性林地二年生阿拉伯蒿（Arabis laevigata var. laevigata）种群种子传播的物候和模式（方向和距离）。在一些植物中，种子在6月成熟后不久就开始扩散，持续了大约2.5年。到1986年9月22日，种群中1986年制种植物上50%的种子已经传播，到1987年3月2日，大约92%的种子已经传播。单株种子传播时间为14 ~ 586 d（平均+/- SE = 202 +/- 12.8 d）。大部分种子都落了下来
Phenology and pattern (direction and distance from mother plant) of seed dispersal were monitored in a population of the facultative woodland biennial Arabis laevigata var. laevigata. Dispersal began soon after seeds matured in June and lasted >2.5 years in some plants. Fifty percent of the seeds on 1986 seed-producing plants in the population had been dispersed by 22 September 1986 and about 92% by 2 March 1987. Length of time an individual plant dispersed seeds ranged from 14 to 586 days (mean +/- SE = 202 +/- 12.8 days). The majority of seeds fell
