Trait diversity in recalcitrant seeds

Published 19 April, 2024

Recalcitrant-seeded species form a crucial component within tropical forests, predominantly comprising trees, among them many commercially valuable members of significant plant families like Fagaceae (oaks), Arecaceae (palms), and Dipterocarpaceae (dipterocarps). The defining trait of such seeds is desiccation sensitivity (DS), which precludes their preservation under conventional seed banking conditions (dry and cold) and limits their ability to survive in situ in the way that orthodox (desiccation tolerant) seeds might persist in the soil seed bank. The presence of the DS trait implies that these species likely evolved a spectrum of pre- and post-harvest survival strategies to ensure successful dispersal, germination and seedling production, thus enabling their survival in their natural habitats.

Recalcitrant seeds of (A) Syzygium cumini (Myrtaceae), (B) Trichilia emetica (Meiliaceae); (C) Caryota urens (Arecaceae) and (D) Ravenea rivularis (Arecaceae).
