【摘要】 用不同浓度三十烷醇(TA乳粉)植物生长调节剂浸泡海带苗,观察其对海带生长的影响。结果表明:以0.8 mg/L浸泡海带苗的增产效果最佳,增产幅度达20.5%,其次为1.0 mg/L和1.5 mg/L,分别增产16.3%和13.1%;对生长速度、藻体色泽、藻体宽度、抗病能力等方面也有明显影响。更多还原

【Abstract】 Using plant growth regulator triacontanol(TA) as raw material,five experimental groups were established for the control study of the effects on the growth of kelp seedlings’ algae soaked in different concentrations of TA.The study showed that kelp seedlings soaked in TA with the concentration of 0.8 mg/L yielded the best result,the production was increased by 20.5%,followed by kelp seedlings soaked in TA with the concentration of 1.0 mg/L and 1.5 mg/L,with the production being increased by 16.3% and 13.1% respectively.It also showed significant effect of TA on the kelp seedlings’ growth rate,algae color,width and disease resistance.更多还原
