摘要
用０．０００５、０．００１、０．００３、０．００５、０．００７ｍｏｌ·Ｌ－１浓度的ＮａＮ３诱发油用向日葵突变。结果表明，油葵Ｍ１的发芽率、出苗率和幼苗高度均随ＮａＮ３浓度的提高而降低。ＮａＮ３诱发向日葵的适宜浓度为近于或略高于０．００７ｍｏｌ·Ｌ－１，高于诱发禾本科作物突变的适宜浓度。
Seeds of sunflower were treated by NaN3 with 0. 0005mol. L-1, 0. 001mol·L-1,0. 003mol·L-1,0. 005mol·L-1 and 0. 007mol. L-1. The results indicated that rate ofgermination, rate of emergence and seedling height were reduced with the increase of concentrations of NaN3. The concentration of 0. 007mol·L-1 or slightly over 0. 007mol·L-1 of NaN3 were suggested to be suitable for obtaining mutant of sunflower, which exceeded that in grasses.
