摘要
以云烟87为材料,研究8%胺鲜酯(DA-6)(质量浓度15.0、10.0、5.0μg/L)与10.0 mmol/L氯化钙配施对烤烟育苗的影响。结果表明:与清水对照相比,播种7d和15d后配施处理的烤烟出苗率分别提高4.50%~10.40%、2.74%~8.33%,成苗率提高3.19%~8.81%;成苗期的苗高、茎基宽、最大叶叶面积分别提高了5.99%~17.66%、1.29%~5.47%、21.1%~73.6%;根、茎、叶、全苗干物质积累量分别提高了25.0%~55.0%、16.7%~33.3%、14.1%~33.8%、16.5%~36.9%,根冠比提高了9.1%~17.0%;配施处理的叶片叶绿素(叶绿素a+叶绿素b)含量增加26.0%~64.9%;配施处理硝酸还原酶活性提高了52.1%~95.9%;过氧化氢酶(CAT)活性、过氧化物酶(POD)活性、超氧化物歧化酶(SOD)活性及丙二醛(MDA)含量分别降低了41.5%~59.3%、27.9%~62.9%、30.3%~81.1%和34.0%~63.7%,表明用10μg/L DA-6+10 mmol/L氯化钙配施浸种效果最佳。
Based on Yunyan87 testing material,we examined the influence of 15.0,10.0,5.0μg/L concentrations of 8%diethyl aminoethyl hexanoate(DA-6)either singularly applied or applied in combination with calcium chloride on germination and seedling quality of flue-cured tobacco seeds.The results highlighted that:compared to the control treated with water,the emergence rate at 7th and 14th day after sowing were increased by 4.50%-10.40%and 2.74%-8.33%respectively,the seedling rate were increased by 3.19%-8.81%in the combined treatment,and in seedling period,seedling height,stem basal width,maximum leaf area were improved in the combined treatment by 5.99%-17.66%,1.29%-5.47%and 21.1%-73.6%respectively;dry matter accumulation of root,stem,leaf,full stand of seeding and root-to-leaf ratio with combined treatment showed a progressive increase by 25.0%-55.0%,16.7%-33.3%,14.1%-33.8%,16.5%-36.9%and 9.1%-17.0%,respectively,the content of leaf chlorophyll(chlorophyll a+chlorophyll b)with combined treatment was augmented by 26.0%-64.9%;the activity of nitrate reductase with combined treatment elevated by 52.1%-95.9%;catalase(CAT)activity,peroxidase(POD)activity,superoxide dismutase(SOD)enzyme activity and malondialdehyde(MDA)content with combined treatment were decreased by 41.5%-59.3%,27.9%-62.9%,30.3%-81.1%and 34.0%-63.7%,respectively.In conclusion,Yunyan87 seeds treated with 10.0µg/L DA-6 in combination with 10.0 mmol/L calcium chloride showed the best effect.
