Outline of Final Research Achievements

We conducted transplant experiment in Arabidopsis kamchatica and detected home-site advantage by origin. Leaf trichome and life-history worked as adaptive traits. We obtained seeds in transplant gardens and conducted re-transplant experiment. Environment, which parent generation experienced, affected fitness of offspring generation. However, the trend of home-site advantage by parent environment was not consistent, claiming more studies for transgenerational adaptive effects.
