Napus genotype and the structure of F& hybrids. The effet of the hybrid structure was considerable : at the meiosis of AAC triploid hybnrids, resulting from crosses between B. Napus and B. Rapa, recombination rates were from 1. 8 to 3. 4 fold higher than in AACC tetrploid hybrids, ...
The concentration of seedlings at the base of trees was primarily dependent on a short distance dispersal following a rapid and complete opening of the cones after the fire and, secondly, on the quality of the microsites.Jacques FilionHubert Morincanadian journal of forest research...
