Abstract: Saraca asoca and Caesalpinia pulcherrima of the subfamily Caesalpiniaceae bear away by dry dehiscent pods. In spite of their similarity in mechanical dispersal, seeds of S. asoca are desiccation sensitive while that of C. pulcherrima are desiccation tolerant. For complete development, S. asoca seeds take 120 Days After Anthesis (DAA) whereas C. pulcherrima requires only 75 DAA. Mature seeds of S. asoca with 100% germination have high Moisture Content (MC) of 52.6%. On maturation drying, the MC of C. pulcherrima seeds become 9.5 with 83% germination. Seeds of S. asoca germinate from 60 DAA onwards but that of C. pulcherrima germinate only after seed maturation drying of 75 DAA. Presence of oligosaccharide like raffinose along with sucrose in C. pulcherrima also hints an orthodox seed lineage against the recalcitrant nature of S. asoca seeds. Aspects like maturation drying, germination, desiccation response, leachate conductivity and sugar composition were studied for finding facts of species specific distinct seed lineage.
