查询词典 sampled

Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.
