13 367 Recalcitrant seed storage lifespan varies from 2-3 weeks for some tropical species to 2-3 years 368 for chilling-tolerant temperate species stored at low temperatures. Generally, the more rapidly a 369 recalcitrant seed species germinates, the shorter is its storage lifespan.5 Temperatures lower than 15 o C generally reduce recalcitrant seed longevity and this tendency can 36 also be used as a basis to define the degree of recalcitrance. However, the lack of desiccation 37 tolerance is still considered the major difference between orthodox and recalcitrant seeds.
