The East Indian sandalwood (Santalum album L), one among the valued timber species in the global market due to its sweet-scented heartwood, is facing a drastic decline of its natural populations over the past three decades. The major constraint in the regeneration of sandal is the slow, staggered, and poor germination of the seeds. The germination may continue even up to one year. The present investigation focused on the impact of biopriming on the germination and seedling performance in sandal. Fresh mature seeds of sandal were procured from the Nachivayal Reserve Forest, Marayur Sandal Division. The seeds were subjected to 16 biopriming treatments using Pseudomonas fluorescens at 4 concentrations (25, 50, 75 and 100%) and 4 durations (2, 4, 6, and 8 days). The results revealed that the biopriming at 100% for 8 days recorded the highest germination percentage (88%) within 21 days with lowest energy period (15 days) and highest germination energy (62.98%). Biopriming at 50% concentration for 8 days was the next best treatment which improved the germination of sandal seeds and the lowest germination percentage was recorded in control seeds (46%). With regard to the seedling growth, the biopriming treatment contributed a significant increase in growth attributes of the seedlings. We recommend the biopriming with Pseudomonas fluorescens at 100% for 8 days as a potential technique to enhance seed germination and seedling growth in sandal.

东印度檀香（Santalum专辑L），由于其香气浓郁的心材而成为全球市场上珍贵的木材之一，在过去的三十年中，其自然人口急剧减少。凉鞋再生的主要限制因素是种子缓慢，交错和发芽差。发芽可能会持续长达一年。本研究侧重于生物引发对凉鞋萌发和幼苗生长的影响。新鲜的凉鞋成熟种子是从Marayur凉鞋分部的Nachivayal保护林采购的。使用荧光假单胞菌对种子进行16次生物引发处理4种浓度（25％，50％，75％和100％）和4种持续时间（2、4、6和8天）。结果显示，在21天的100％生物引发中，发芽率最高（88％），在21天之内具有最低的能量期（15天）和最高的发芽能（62.98％）。次佳的处理方法是在浓度为50％的条件下进行8天的生物引发处理，从而改善凉鞋种子的发芽率，而对照种子的发芽率最低（46％）。关于幼苗的生长，生物引发处理显着增加了幼苗的生长特性。我们建议以100％的荧光假单胞菌进行生物引发8天，作为增强凉鞋种子发芽和幼苗生长的潜在技术。
