Studies on synchronising seed germination in red sanders (Pterocarpus santalinus)

Pterocarpus santalinus is valued for its heavy dark claret-red heartwood which possesses indomitable challenges in seed propagation. This study was conducted to improve seed germination in red sanders. Seeds and fruits were collected from the elite trees of Vellore district Tamil Nadu to elicit information on the pod seed germination and its improvement methods. Freshly collected and harvested seeds had poor germination (33) with germination period ranging between 14 to 53 days. The poor and staggered germinability of red sander was due to the presence of phenolic compounds and hormonal imbalance in pod and seed respectively. Significant increase in germination percentage with reduced germination period was observed when seeds were soaked for 48 hours and changing the water every 12 hours followed by soaking in 500 ppm of GA‚ for 12 hours. These combination of soaking the red sander seeds in water followed by GA‚ can be employed for early synchronised higher germination.

Abstract

Pterocarpus santalinus is valued for its heavy dark claret-red heartwood which possesses indomitable challenges in seed propagation. This study was conducted to improve seed germination in red sanders. Seeds and fruits were collected from the elite trees of Vellore district Tamil Nadu to elicit information on the pod seed germination and its improvement methods. Freshly collected and harvested seeds had poor germination (33) with germination period ranging between 14 to 53 days. The poor and staggered germinability of red sander was due to the presence of phenolic compounds and hormonal imbalance in pod and seed respectively. Significant increase in germination percentage with reduced germination period was observed when seeds were soaked for 48 hours and changing the water every 12 hours followed by soaking in 500 ppm of GA‚ for 12 hours. These combination of soaking the red sander seeds in water followed by GA‚ can be employed for early synchronised higher germination.
