Examplesofdormancydormancy Finally, in red rice, both primarydormancybreaking and secondarydormancyinducibility follow decay kinetics during afterripening. From theCambridge English Corpus Effects of dispersers, gaps, and predators ondormancyand seedling emergence in a tropical herb. From theCambridge English Corpus Thus, in the absence ofdormancy, delayed and slower rates of germination are evidence of reduced seed vigour and quality. From theCambridge English Corpus Seedling emergence is restricted to spring because a number of environmental signals are required to breakdormancyand/or to induce germination. From theCambridge English Corpus Due to the fact that multiple environmental signals regulatedormancy, seedling emergence in these species is timed very accurately in spring. From theCambridge English Corpus A longer period of storage in moist soil (approximately 15 d) was required to produce a decrease in thedormancylevel of the seed population. From theCambridge English Corpus The timing of seed transfer from storage to incubation was based on how rapidly seeds lostdormancy. From theCambridge English Corpus These findings highlight that conditions of seed storage can alter seeddormancy, and hence, influence their response to stimulants such as smoke water. From theCambridge English Corpus Conversely, an increase in thedormancylevel of the seed population was observed after periods of storage in dry soil. From theCambridge English Corpus They were removed and the remaining (dormant) seeds were used in the experiments and are referred to as seeds with primarydormancy. From theCambridge English Corpus Therefore, it seems that germination conditions such as high and fluctuating temperatures and moisture strengthen thedormancyof deeply dormant seeds. From theCambridge English Corpus Conditionaldormancyis induced in late spring/summer, and then during the second late autumn/winter period after dispersal seeds again become non-dormant. From theCambridge English Corpus However, it is not known whether uptake of water also occurs through the chalazal region after breaking of physicaldormancy. From theCambridge English Corpus Seed-coat characteristics are a key in the development of physicaldormancy, as they affect water uptake and gas exchange. From theCambridge English Corpus For secondarydormancystudies, viability of ungerminated embryos was assessed visually.
