| 释义 | dormancy noun[ U ] uk /ˈdɔː.mən.si/ us /ˈdɔːr.mən.si/ the state of being dormant(= not active or growing but able to become active later): 休眠状态 Warm temperatures bring the seeds out of dormancy.温暖的温度唤醒了休眠的种子。 Passive and not working adynamic anywhere breather breathing space bum bum around idle laze leave someone beidiom lie around moribund navel non-physical recharge siesta sit on your handsidiom sit round slob slob around (something) slop around (something) Examples of dormancydormancy Finally, in red rice, both primary dormancy breaking and secondary dormancy inducibility follow decay kinetics during afterripening. Effects of dispersers, gaps, and predators on dormancy and seedling emergence in a tropical herb. Thus, in the absence of dormancy, delayed and slower rates of germination are evidence of reduced seed vigour and quality. Seedling emergence is restricted to spring because a number of environmental signals are required to break dormancy and/or to induce germination. Due to the fact that multiple environmental signals regulate dormancy, seedling emergence in these species is timed very accurately in spring. A longer period of storage in moist soil (approximately 15 d) was required to produce a decrease in the dormancy level of the seed population. The timing of seed transfer from storage to incubation was based on how rapidly seeds lost dormancy. These findings highlight that conditions of seed storage can alter seed dormancy, and hence, influence their response to stimulants such as smoke water. Conversely, an increase in the dormancy level of the seed population was observed after periods of storage in dry soil. They were removed and the remaining (dormant) seeds were used in the experiments and are referred to as seeds with primary dormancy. Therefore, it seems that germination conditions such as high and fluctuating temperatures and moisture strengthen the dormancy of deeply dormant seeds. Conditional dormancy is induced in late spring/summer, and then during the second late autumn/winter period after dispersal seeds again become non-dormant. However, it is not known whether uptake of water also occurs through the chalazal region after breaking of physical dormancy. Seed-coat characteristics are a key in the development of physical dormancy, as they affect water uptake and gas exchange. For secondary dormancy studies, viability of ungerminated embryos was assessed visually. These examples are from corpora and from sources on the web.
