| 中文摘要: |
| 以3种不同熟期的马铃薯为材料，研究了赤霉素（GA3）对马铃薯生长与开花的影响，旨在为马铃薯杂交
育种、花期调控提供参考依据。结果表明院GA3能促进马铃薯植株的生长，使叶片叶绿素下降，能促进开花性弱的早熟
材料开花，提前并延长开花性强的中晚熟材料的花期。 |
| 英文摘要: |
| In order to explore the effects of application of seed-coating agents on hybrid rice in seedling, the hybrid
rice seeds of Shenliangyou5814 were coated with 2.5% imidacloprid-prochloraz, 3% hymexazole-prochloraz, Cruiser and
Celest, respectively, and the germination rate, the percentage establishment of seedling, the seedling quality and the control
effect of rice thrips were investigated. The results showed Cruiser and 3% hymexazole-prochloraz promoted the germination
rate, but the percentage establishment of seedling showed no significant difference among the seeds coated with the four
seed-coating agents. The plant height, leaf area and total root number showed no difference between the seeds coated with
the four seed-coating agents and the control seeds, but the plant height dealed with Cruiser was higher than that dealed
with 3% hymexazole-prochloraz, the leaf area dealed with Cruiser was larger than that dealed with 2.5% imidaclopridprochloraz,
the total root number dealed with Cruiser were larger than that dealed with 3% hymexazole-prochloraa and
2.5% imidacloprid-prochloraa, and the seedling dry weight dealed with Cruiser was higher than that dealed with 2.5%
imidacloprid-prochloraz. The comprehensive seedling quality of rice seeds dealed with Cruiser was the best. The four
seed-coating agents showed control effect to rice thrips. Among them, Cruiser and 2.5% imidacloprid-prochloraz were more
effective. |
