Sammanfattning

The meiotic development in pollen mother cells of Larix decidua, L. leptolepis and L. sibirica growing at different localities In Sweden was studied. The percentage of completely damaged buds as well as the pollen sterility was estimated. The reaching of diplotene took place earlier in L, sibirica than in L. decidua and L. leptolepis. The second phase of high frost sensitivity (diakinesis - telophase II, except for the interphase) in the PMC appeared in the sequence L. sibirica - L. leptolepis - L, decidua. Differences within a species from locality to locality regarding the initiation of further development from diplotene could be attributed to differences in temperature conditions at the different growth localities. The same was true for the induction of completely damaged buds
