为了提高水青冈种子的发芽率，本研究以水青冈种子为材料，研究了不同浸种处理和浸种时间对种子发芽率的影响。单独或与向发芽基质中添加赤霉酸组合。除测试对照种子外，还测定了7个浸泡期。室温下用自来水浸种24 h，15、30、45、60、75和90 d。在生长室中的封闭培养皿中进行发芽试验。将发芽数据拟合为逻辑斯蒂函数，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。30天或更长时间的浸泡期增强了种子发芽：最终发芽值范围为95%至99%，减少了达到50%最终发芽的时间，从而减少了发芽试验的持续时间。添加赤霉酸浸泡后的基板提高发芽只有对照种子和那些浸泡24它或15天。种子浸泡30或45天，然后向基质中加入或不加入赤霉酸溶液。是提高刺山柑种子发芽率的有效方法。
In order to improve caper seed germination, this two-year study (2005-2006) was designed to determine the effects of seed soaking treatments and soaking times. individually or in combination with the addition of gibberellic acid to the germination substrate. Besides testing the control seeds, 7 soaking periods were assayed. soaking seeds in tap water at room temperature for 24 h, 15, 30, 45, 60, 75 and 90 days. Germination tests were performed in closed Petri dishes in a growth chamber. Germination data were fitted to the logistic function and calculations were made for the maximum germination percentage, the time to reach 50% of final germination and the mean relative cumulative rate. A soaking period of 30 days or longer enhanced seed germination: final germination values ranged from 95 to 99%, reducing the time to reach 50% of final germination and consequently the duration of germination tests. Addition of gibberellic acid to the substrate after soaking improved germination only for control seeds and those soaked for 24 It or 15 days. Seed soaking for 30 or 45 days, followed or not by the addition of a gibberellic acid Solution to the substrate. is an efficient method to enhance caper seed germination.
