Ber (Ziziphus mauritiana) produces orthodox seeds capable of surviving desiccation down to low moisture (<5%) and sub-zero temperature storage without loss of viability; mango, jackfruit, and litchi are recalcitrant.

• Ber: Classical orthodox fruit seed with a stony endocarp that withstands severe drying and long-term cold storage.
• Jackfruit: Recalcitrant seed that dies if dried below critical moisture (~30%).
• Litchi: Highly recalcitrant tropical seed with rapid loss of viability upon desiccation.
• Mango: Recalcitrant seed stone that cannot tolerate drying or chilling below 10°C.
