- 摘要:
- 以‘潍县萝卜’为试材,于三叶期喷施不同浓度的烯效唑(S3307)、脱落酸(ABA)、青鲜素(MH)和矮壮素(CCC),调查萝卜的现蕾率和抽薹率,并测定萝卜叶片C/N的变化。结果表明:S3307、ABA、MH和CCC喷施处理萝卜幼苗表现为不同程度的矮化、健壮,抽薹率分别比对照降低421%、141%、906%、237%,其中MH处理严重抑制生长。烯效唑600 mg/L处理使萝卜叶片内C/N下降802%,有效地降低了植株的现蕾率、抽薹率(分别下降673%、598%),在春季萝卜反季节生产中使用能有效延缓现蕾抽薹的进程。
- Abstract:
- Taking radish ‘Weixian’ as experimental material,different concentrations of Uniconazole(S3307),Abscisic Acid(ABA),Maleic hydrazide(MH) and Chlorcholinchlorid (CCC) four kinds of plant growth regulators were sprayed on seedlings at trefoil stage to explore the inhibition effects of plant growth regulators on bolting of anti-season radish cultivation.In this experiment, the budding rate,the bolting rate and changes of C/N ratio were investigated.The results showed that compared with the control, four kinds of plant growth regulators, four days of spraying time and a total of four times,made seedlings dwarf and strong in various concentrations.The treatment of S3307,ABA,MH and CCC led to radish bolting rate descending 421%,141%,906%,237% respectively, in which the treatment of MH severely inhibited plant growth.The treatment of Uniconazole 600 mg/L decreased the radish leaf C/N ratio to 802%,effectively reduced the budding rate and the bolting rate (decreased by 673%,598%) of plants, it was suitable for spring anti-season radish cultivation and relieve the budding process.
