Table 1. The continuum proposed to account for varying degrees of recalcitrance (Farrant et al., 1988).
Types of Recalcitrance
Fair amount of water loss tolerated
Moderate account of water loss tolerated
Little water loss tolerated
Germination slow in absence of additional water
Moderate germination rate in absence of additional water
Fast germination in absence of additional water
Lower temperature tolerated
Most species are temperature sensitive
Most species temperature sensitive
Ex.: Quercus, Araucária, Podocarpus
Tropical distribution Ex.: Theobroma, Hevea
Inhabit tropical forests and wetlands.
Ex.: Avicennia marina, Syzygum sp.
