| | Résumé : | To account for observed patterns of emergence in the warm temperate grasslands of Japan the seed germination of several dozen species was tested following various types of thermal pre-treatment. An enormous variety of responses was observed among the species, especially in the capacity for immediate germination and the responses to moist storage with chilling. The extent of chilling requirement for the breakage of primary dormancy was largely correlated with the timing of seed dispersal, spring-summer dispersers tending to have a larger chilling requirement. On the other hand, the seedling emergence phenology of the species was closely related to the temperature dependency of the germination of non-dormant seeds. | | Type de document : | Tiré à part | | Permalien de la notice : | https://infodoc.agroparistech.fr/index.php?lvl=notice_display&id=148040 |
