| 摘 要： | 通过对两个郁金香品种Judith Leyster(凯旋型)和Big Smile(达尔文杂种型)分级栽植后花径、种球繁殖系数等几项指标的调查统计分析,结果表明,2个品种质量增幅随种球等级增大呈先上升后下降趋势,Judith Leyster繁殖系数大,种球直径大于3.272 cm可以开花,在2.508 cm以上繁殖后可获得1级种球;BigSmile产量高,种球直径大于2.5 cm可以开花,在2.216 cm以上种植后可获得1级种球,2个品种1级、2级和3级种球可作为繁殖商品球的材料,4级和5级种球可作为大量繁殖子球用。

| Abstract: | Two varieties of tulip bulb,Judith Leyster(Triumph tulip) and Big Smile(Darwin hybrid tulip),were planted on gradation and compared indexes including the flower diameter,propagation coefficient,and rate of yield in the experiment.The result revealed that with the enlarging of bulb grade,mass increment of the two varieties was firstly fast and then small;Comparing to the two cultivars,the bu1b yie1d of Big Smile was higher than that of Judith Leyster,but the propagation coefficients was low.For Judith Leyste... |
