Seed dormancy concepts in orchids: Dendrobium cruentum as a model species.
Generally, orchids produce dust-like seeds in which endosperm reduction and embryo undifferentiation represent a derived state shared with species in about 11 other plant families. Orchid seeds are proposed to have a special kind of morphological or morphophysiological dormancy. We test this proposition, overcoming several design limitations of earlier studies,...Prasongsom, Sasikarn ; Thammasiri, Kanchit ; Pritchard, Hugh W.

Pericarp structure of Glebionis coronaria (L.) Cass. ex Spach (Asteraceae) cypselae controls water uptake during germination.
(L.) Cass. ex Spach is a common Mediterranean weed producing distinctive central and peripheral dormant cypselae with a hard fruit coat, which was previously hypothesized to impose physical dormancy. Analysis of water uptake in cypselae and in naked seeds showed that it preferentially takes place at the basal end of...Garland chrysanthemum, Heterocarpy, Imbibition, Pericarp constraint, Glebionis coronaria, Germination, and Dormancy

Trade‐off between seed dispersal in space and time.
Seed movement and delayed germination have long been thought to represent alternative risk‐spreading strategies, but current evidence covers limited scales and yields mixed results. Here we present the first global‐scale test of a negative correlation between dispersal and dormancy. The result demonstrates a strong and consistent pattern that species with...Chen, Si‐Chong ; Poschlod, Peter ; Antonelli, Alexandre ; Liu, Udayangani ; Dickie, John B.
