Introduction to Secondary Dormancy

has little or no primary dormancy, but exhibits great variation in secondary dormancy.

Secondary dormancy was induced during the rainy season and alleviated during the dry season, following a conditional dormancy/dormancy cycle.

Seed TIPs also contribute to the regulation of depth of primary dormancy and differences in the induction of secondary dormancy during dormancy cycling.

Not only primary dormancy, but also secondary dormancy in response to high temperature was increased by the loss-of-function.

Extended warm conditioning, on the other hand, elicited a return to dormancy, or secondary dormancy, in nondormant cysts.

This study examined maternal effects in Polygonum aviculare on release of seed primary dormancy, responses to alternating temperatures, induction into secondary dormancy, and field emergence patterns as influenced by changes in the sowing date and photoperiod experienced by the mother plant.

Secondary dormancy can be induced in imbibed seeds when they encounter prolonged unfavourable conditions.

However, a portion of the seeds can be induced into a light‐requiring state (secondary dormancy) for germination and also exhibit dormancy cycling.

The results demonstrated that during storage the seeds developed a possible secondary dormancy, which was overcome with a time of twelve months of storage.

Other mechanisms of temporal habitat choice include (1) the controls on seed dormancy and germination, (2) the evolution of secondary dormancy in plants of unpredictable habitats, (3) the germination of certain desert species only when enough rain for the completion of the life cycle has fallen, and (4) the timing of fruit ripening to coincide with the arrival of their dispersers.

In the absence of a suitable host, seeds will go back into a state of secondary dormancy.

Furthermore, this species has been described to have a secondary dormancy that is dependent on the environment.

Oppositely, high temperature and unfit humidity induced secondary dormancy via inhibitors released by bracteoles.

Exposure of the seeds to ranges of temperatures at 15/25 °C and 20/30 °C resulted in secondary dormancy.

) after dispersal in the autumn and the induction of secondary dormancy the first summer following seed dispersal limit the regeneration of mixed broadleaved Korean pine forests in Northeast China.

Highlight The ERECTA family of receptor-kinases regulates seed germination under salinity, through mucilage-mediated sensing of conditions at the seed surface, and interaction with secondary dormancy mechanisms.

Hypoxic floodwaters did not reinforced dormancy yet hindered secondary dormancy induction by warm temperatures.
