Abstract
以6個玉米自交系及其相互雜交（正交）所獲得的15個F1單交種為材料，在4種銨離子[NH4(上标 +)](5、25、50、100m)濃度下，於溫室砂耕中進行試驗。經16天的處理後，所獲得之數據經變方分析結果顯示銨離子濃度間、基因型間與銨離子濃度×基因型之交感作用對幼苗地上部乾物重、根部乾物重與整株總乾物重均有極顯著之影響。
Fifteen F1 cross combinations and their parental inbred lines of maize (Zea mays L.) were analyzed in this study. Four replicates, 3 plants of each genotypes, were tested at the concentrations (5, 25, 50, 100 mM) of ammonium (NH4(superscript +)) to evaluate the tolerance of maize inbreds and hybrids to ammonium-nitrogen (NH4(superscript +)-N) maize seedlings were grown in sand culture and supplemented with different concentrations of ammonium in green house, seedlings were harvested at 16 days after application of ammonium-nitrogen (NH4(superscript +)-N) to determine the shoot, root and total dry mass.
