中文摘要: |
采用不同浓度(50、75、100、125、150 mg/L)的多效唑对向日葵进行叶面喷施,研究多效唑对向
日葵生长及产量品质的影响。结果表明,多效唑各浓度处理能不同程度地抑制向日葵株高、增加向日葵茎粗、
缩短向日葵节间长和叶柄长、减小向日葵叶片叶长与叶宽、减少叶片数、增加向日葵盘径、单盘粒重、百粒
重、提高籽仁率,增产效果明显,同时能改善向日葵籽粒品质,提高籽粒粗蛋白和粗脂肪含量等。综合向日葵
生长、产量品质性状考虑,多效唑75 mg/L 处理在试验中表现最佳。 |
英文摘要: |
In order to study the effects of paclobutrazol on the growth,yield and quality of sunflower,different
concentrations of paclobutrazol(50,75,100,125,150 mg/L)were sprayed on the leaves of sunflower. The results
showed that paclobutrazol treatment had different degrees of inhibition on sunflower plant height,increased the sunflower
stem diameter,shortened the sunflower internode length and petiole,reduced the sunflower leaf length and width,
decreased the leaf number,increased the sunflower plate diameter,single plate grain weight and hundred grain weight,
increased the rate of seed kernels,increased yield,at the same time could improve the quality of sunflower seeds,
improve the grain crude protein and crude fat content and so on. The results indicated that sunflower sprayed by 75 mg/L
of paclobutrazol performed best. |
