Seed size and chilling affect germination of Larix decidua Mill, seeds

摘要

We tested whether seed size and cold chilling impact on seed germination for seven populations of the conifer species Larix decidua. For all seven populations, seed germinability was positively related to seed mass: larger seeds germinated to a higherpercentage. In addition, cold chilling also had a positive affect on germination for all seven populations. Our data suggest that the selection of the larger seeds in the population and cold chilling are likely to be of benefit for seedling production of this species.
