本研究分析了7种处理对破硬粒和4种处理对破休眠的效果。种子在生长室中发芽，并计算最大发芽率、达到最终发芽50%的时间和平均相对累积速率。Logistic函数适用于分析刺山柑种子萌发。在发芽基质中加入GA（3）溶液进行酸蚀处理是确保种子发芽的最佳、有效和成本有效的方法。酸划痕法可以用超声波机械划痕法代替。热水松土或浸泡，但这些程序需要较长的发芽期，以达到令人满意的发芽水平。结果表明，浸泡法能有效地去除硬实，而且是试验处理中最简单的方法。
This study analyses the effects of seven treatments for removing hardseededness and four for breaking physiological dormancy in caper seeds. Seeds were germinated in a growth chamber and the maximum germination percentage, the time to reach 50% of final germination and the mean relative cumulative rate were calculated. The logistic function was suitable for analysing caper seed germination. Acid scarification followed by the addition of a GA(3) solution to the germination substrate was the best, efficient and cost effective method for ensuring satisfactory seed germination. Acid scarification can be substituted by mechanical scarification with ultrasound. hot water scarification or soaking, but these procedures require longer germination periods to reach satisfactory germination levels. The soaking method proved useful enough to remove hardseededness and it is also the most simple among the assayed treatments.
