| 摘 要： | 利用不同质量浓度的矮壮素喷洒一年生香椿实生苗。结果表明：①矮壮素500g／m^3、1000g／m^3、2000g／m^3质量浓度对一年生香椿实生苗木质化具有极显著促进作用，且单位面积Ⅰ、Ⅱ级苗木株数随浓度增大而增加，矮壮素250g／m^3质量浓度对香椿木质化的促进作用不明显。②乙烯利的4个质量浓度对一年生香椿实生苗木质化均具有极显著促进作用，在250g／m^3、500g/m^3、1000g／m^3质量浓度等级中，单位面积Ⅰ、Ⅱ级苗木株数随浓度增大而增加，在2000g／m^3质量浓度时，单位面积Ⅰ、Ⅱ级苗株数反而减少。

| Abstract: | The effects of two plant growth regulators,cycocel(CCC) and ethrel,on the lignificatin of the one-year-old seedlings of Toona sinensis were studied.The result showed that: 1) application of cycocel(CCC)at 500,1000,2000ppm significantly enhanced the lignification of the seedlings,while the concentration of 250ppm had no obvious effect,and with the increase of the concentration,the number of the grade-I and grade-II seedlings per unit area increased;2)application of ethrel at 4 different concentrations all si... |
