Abstract: In order to understand the effect of selenium on the yield of garlic and its absorption and transformation , the experiment was carried out through three different ways , namely leaf absorption , seed soaking and soil application. It was found that the ability to absorb selenium varied
among the four garlic varieties , the highest of which was ‘Yingxian’garlic , and followed by ‘Xinzhou’, ‘Yuci’and ‘Taigu’. Under the range of selenium concentration in this experiment , with the rise of selenium concentration , the yield of garlic increased and then dropped , whereas the
total content of selnium in garlic increased steadily with the decrease of the ratio of inorganic Se to organic Se.
